A beam trolley is a wheeled trolley that clamps over the bottom flange of a structural I-beam, H-beam or universal beam and carries a chain block, lever block or electric hoist along it. The combination — beam + trolley + hoist — is a monorail lifting system: vertical lift from the hoist, horizontal travel from the trolley along the beam. It's the missing piece between a beam clamp (static lift point) and an overhead crane (full bridge across two beams). Workshop fabrication, mining maintenance, engine bays, heavy-machinery service, food processing, pharmaceutical and agricultural workshops all use beam trolleys to move suspended loads where a fixed lift point would mean repositioning the load or repositioning the lift.
This guide walks the full decision: push vs geared vs motorised travel, flange width sizing (the single biggest selection constraint), Working Load Limit (WLL) matching, AU beam shapes (Universal Beam tapered flange vs Universal Column parallel flange), AS 1418.1 + AS 4991 compliance, close-headroom variants for low-ceiling workshops, hoist compatibility, end-stops and inspection regime. It's written for AU fabrication shops, mining maintenance, automotive workshops, mobile plant repair and the residential/garage workshop crowd — with an explicit safety warning on residential beam ratings.

What is a beam trolley?
A beam trolley (also called a girder trolley, I-beam trolley or beam-running trolley) is a four-wheeled carrier with adjustable side plates that clamps the bottom flange of an overhead beam. The wheels roll on the top surface of the bottom flange; the side plates locate against the flange edges; the hoist hangs from a lifting eye, lug or hook at the base of the trolley. Travel along the beam is by push (operator hand-force on the load), geared hand-chain (mechanical advantage via gear wheel and hand chain), or electric motor.
The trolley is half of a two-part system. The other half is the beam itself — a steel I-beam, H-beam or universal beam rated for the trolley + hoist + load combined weight. Beam selection is engineering work; trolley selection is largely a matching exercise to the beam you already have. From r/Rigging: "An I beam is the way to go, with a trolley on the beam. You can attach a motorised or manual chain hoist on to the trolley." That's the standard combo — fixed overhead beam, travelling trolley, hoist hanging from trolley.
This is NOT a golf, baby, beach or shopping trolley
One forensic note before going further: the keyword "push trolley" collides with consumer product categories that are unrelated to industrial lifting. If you are here for golf push carts, baby walking trolleys, beach carts or shopping trolleys, you are in the wrong place — see specialty retailers (Drummond Golf, Baby Bunting, Kmart) for those product classes.
This guide is industrial lifting beam trolleys only: hoist carriers, monorail systems, workshop lifting, mining maintenance, fab shop overhead handling. The four-wheeled clamping trolley that runs on the bottom flange of a structural beam and carries a chain block, lever block or electric hoist.
Push vs geared vs motorised — the three travel mechanisms
| Type | Travel mechanism | Best for | Operator effort | AIMS examples |
|---|---|---|---|---|
| Push trolley | Operator pushes the suspended load by hand; trolley wheels roll free | Light loads (up to 2–3 T), short travel, infrequent use, budget-conscious workshops | Direct hand force on load; effort scales with load weight | Beaver Push Girder Trolley (500–10,000 kg range), Beaver Girder Push Trolley Bolt 1000 kg |
| Geared trolley | Hand chain rotates gear wheel which drives the trolley wheels along the beam | Heavier loads (3 T+), longer travel, precise positioning, reduced operator fatigue | Hand-chain pull; mechanical advantage 20:1 to 40:1 depending on gearing | Beaver Close Headroom Geared Girder Trolley (1000–10,000 kg), Austlift Geared Trolley GT01, Garrick Geared Trolley |
| Motorised / electric trolley | Electric motor drives trolley wheels via gear reduction | Heavy loads, frequent travel, production cycles, long beam runs, low operator workload | Push button / pendant control; no operator effort | Pacific Porta Hoist Single Phase Trolley 500 kg PPHT050 (electric trolley matched to Pacific Porta Hoist Electric Chain Hoist) |
| Trolley + Clamp combo | Trolley integrates beam clamp function in one unit | Mobile / temporary installations, one-off lifting tasks, hire fleets | Single attachment + travel mechanism | Beaver YC Trolley & Girder Clamp 2000kg, Austlift Girder Clamp Trolley |
The selection rule is light/medium + short travel + infrequent = push; heavy + long travel + frequent = geared or electric. Most AU workshops at 1–3 T capacity find the geared trolley the practical default — control on heavier loads, less operator fatigue, more precise positioning. Push trolleys win on simplicity and price for lighter workshop applications.
Flange width — the single biggest selection constraint
Before considering capacity, brand or travel mechanism, measure the bottom flange width of your beam. The trolley side plates must adjust to clamp around that flange — and most trolleys have an upper limit on flange width they can accommodate. From Practical Machinist, the practitioner reality: "The beam has a flange of 10 inches, yet 99 percent of all the trolleys out there only go to 8 inches wide."
That's 254 mm beam flange versus 203 mm typical trolley maximum — wide-flange beams will exceed standard trolley adjustment ranges. Plan around the trolley flange capacity at the start, not after buying. The AIMS Beaver range covers the standard AU workshop flange spread:
| Trolley capacity | Flange width range | AIMS product | Typical AU beam fit |
|---|---|---|---|
| 0.5 T to 1 T | 64–152 mm | Beaver Push Girder Trolley (entry variant) | 100UB–150UB Universal Beams |
| 1 T | 64–203 mm | Beaver Girder Push Trolley Bolt 1000 kg | 150UB to 200UB |
| 2 T | 72–200 mm | Beaver YC Trolley & Girder Clamp 2000 kg | 200UB to 250UB |
| 2 T to 3 T | 88–203 mm | Beaver Push Girder Trolley (mid variant) | 200UB to 250UB |
| 3 T to 5 T | 102–305 mm | Beaver Push Girder Trolley (3T+ variant) | 250UB to 310UB |
| 5 T to 10 T | 114–305 mm | Beaver Close Headroom Geared Girder Trolley (heavy variant) | 310UB to 360UB |
| 10 T+ | Custom range | Source on request (Superlift Industrial AU custom up to 30 T) | 360UB and larger custom beams |
The adjustment is by spacer washers or threaded shafts between the two side plates. You set the spacing to match the flange width plus a small clearance — industry rule of thumb is roughly 6 mm (1/4 inch) wider than flange to allow the wheels to roll freely without binding. Too tight and the trolley jams under load; too loose and the trolley can lift off the flange under shock loading or beam camber.
WLL selection — match trolley capacity to your hoist plus load
Working Load Limit (WLL) for the trolley is the maximum static load the trolley wheels and frame are rated to carry. The trolley WLL must equal or exceed the combined weight of:
- The hoist itself (chain block / lever block / electric hoist mass)
- The lifted load (working load)
- Any rigging gear hanging from the hoist hook (slings, shackles, hooks)
From Practical Machinist: "I used a 1 ton Harbor Freight Push Beam Trolley and a 4 ton chain block." The 1 T trolley is matched to a 1 T working load; the chain block at 4 T has spare lifting capacity but the limiting factor for the system is the 1 T trolley. The chain block weight (15–30 kg for a 4 T unit) plus a 1 T load comes well within the 1 T trolley rating.
The compliance reference for AU is AS 1418.2 (serial-hoists and the beam trolleys they run on) and AS 4991:2004 (lifting devices). Beaver girder trolleys are "operationally tested to 150% of their rated capacity" as part of the AU industry standard proof load requirement. Pacific Hoists, Austlift and Garrick Herbert trolleys all carry equivalent proof-load certification.
Beam capacity vs trolley capacity — they are not the same thing
The trolley capacity is one number; the beam capacity is a different number. Both must independently be rated for the load. A 5 T trolley on a beam rated for only 1 T means the trolley is fine and the beam fails. This is the most common engineering misconception in workshop hoist installations.
From Practical Machinist "Flange Bending due to Concentrated Trolley Load": "My concern is the increased concentrated load on the bottom I-beam flange at the trolley wheels. I can't find any design reference on this." The reference exists — CMAA 74 (US Crane Manufacturers Association specification for trolley beams), AS 1418.18 (gantry / monorail design), and structural engineering practice using AS 4100 (steel structures) — but the point is that beam capacity tables in fabrication catalogues assume uniformly distributed load, not the concentrated point load that a trolley wheel applies. The point load is the trolley + hoist + lifted load divided across only the small contact patch where the trolley wheels meet the beam flange.
From Practical Machinist "I-beam ratings": "The way the trolley wheels contact the beam can also reduce the capacity significantly." Beam capacity reductions of 30–50 percent from the uniform-load table values are typical when reanalysed for trolley point loading.
A serious workshop installation needs a structural engineer to confirm the beam is rated for the proposed trolley + hoist + load combination. AS 4100 + AS 1418.18 + CMAA 74 are the design references. AS 4991 + AS 1418.2 govern the trolley + hoist side.
Universal Beam (UB) vs Universal Column (UC) — tapered flange vs parallel flange
Australian structural steel comes in two main shapes that matter for trolley selection. Universal Beams (UB) have a tapered (sloped) lower surface on the bottom flange — the flange is thicker at the web junction and thinner at the edge. Universal Columns (UC) have parallel flanges — the lower surface is flat. Older American Standard (S-shape) and British Standard Beams (BSB) also have tapered flanges; modern W-shapes and AU Universal Columns are parallel.
From Practical Machinist "Overhead crane beam question": "The flange part of the rail is not perpendicular to the web, it tapers down. Different from a true 'I' beam where [flanges are parallel]." The trolley wheel design must match the flange profile — a trolley designed for parallel-flange UC may sit unevenly on a tapered-flange UB, concentrating load on the wheel edge rather than the centre.
| Beam type | Flange profile | Typical AU sizes | Trolley fit |
|---|---|---|---|
| Universal Beam (UB) | Tapered (slopes from web to edge) | 100UB to 610UB (100–610 mm web depth) | Standard girder trolleys; wheel profile matched to tapered flange |
| Universal Column (UC) | Parallel (flat both sides) | 100UC to 310UC (100–310 mm web depth) | Some trolleys parallel-flange specific; check trolley spec |
| American Standard (S-shape) | Tapered (older, US import) | Legacy structural steel | Most AU trolleys fit S-shape; confirm flange width |
| W-shape | Parallel (modern wide-flange) | US import — common in process plants | Same as Universal Column |
| Welded plate girder | Variable — specified by designer | Custom fabrication, heavy industrial | Trolley spec confirmed by design engineer |
For an unfamiliar beam, two-minute measurement: (1) measure the bottom flange width edge-to-edge, (2) check the flange underside for taper (slide a square along it), (3) measure flange thickness at the edge and at the web. UB will show meaningful taper; UC will not.
AS 1418.1 + AS 4991 compliance
Beam trolleys sold in Australia fall under multiple overlapping standards depending on classification. The compliance matrix:
| Standard | Scope | Applies to |
|---|---|---|
| AS 1418.1:2021 | Cranes, hoists and winches: general requirements | Umbrella standard for AU lifting equipment |
| AS 1418.2 | Serial-hoists (chain blocks, lever blocks, electric chain hoists) and the beam trolleys they run on | The trolley element of a hoist-trolley assembly |
| AS 4991:2004 | Lifting devices | The trolley classified as a lifting device. Same standard as beam clamps, lifting hooks and plate clamps. |
| AS 1418.18 | Crane runways and monorails | Design standard for the beam itself |
| AS 4100 | Steel structures | Engineering design standard for the supporting beam |
| AS 2550.10 | Cranes, hoists and winches in-service safe use | Inspection regime for trolleys, hoists and runways |
| AS 3777 | Steel structures: lifting attachments | Permanent welded lifting attachments to beams |
| CPCCLDG3001 | National dogging licence (Certificate of Dogging) | AU operators directing load placement on lifting equipment including trolley-borne hoists |
AU industry standard proof-load testing is 150 percent of rated capacity — Beaver, Austlift, Garrick Herbert and Pacific Hoists trolleys all ship with proof-load test certification covering this requirement. Always retain the certification with your lifting equipment register.
Close headroom trolleys — for low-ceiling workshops
Standard girder trolleys have a vertical "headroom" dimension from the bottom of the beam to the underside of the trolley body where the hoist hook attaches. This vertical loss matters in low-ceiling workshops — every 100 mm of trolley headroom is 100 mm of lifting height you lose to the hook of the hoist.
Close headroom trolleys shorten this dimension by integrating the trolley wheels and hoist attachment into a more compact frame. The Beaver Close Headroom Geared Girder Trolley is the AIMS workshop standard — 1000 kg to 10,000 kg capacity, geared travel, compact vertical profile. Typical headroom reduction is 30–50 mm compared to a standard trolley, gaining the same in lift height.
Trade-off: close-headroom trolleys are typically 10–15 percent more expensive than standard trolleys of the same capacity, and the compact frame can restrict the size of hoist hook that fits. For most AU workshop ceilings (2.7–3.6 m), close headroom is worth specifying. For high-bay industrial buildings (5 m+ ceiling), standard trolleys are fine.
Beam clamp vs trolley — static vs travelling
If your lift doesn't need to travel along the beam — you're lifting from one fixed point to another fixed point — a beam clamp is the right tool. A beam clamp is bolted, screwed or wedge-attached to the beam flange and stays in place; the hoist hangs from the clamp's lifting eye. Lower cost, simpler installation, no travel.
A trolley earns its cost when the load needs to move horizontally along the beam — pick a load from one location, travel it along the beam, set it down at another location. Engine bay work, fabrication lines, multi-station assembly, mining maintenance where parts move along an overhead path. The full lifting cluster includes both: see the Beam Clamp Guide for the static option, this guide for the travelling option. Trolley-with-integrated-clamp products like the Beaver YC Trolley & Girder Clamp combine both functions in one unit — useful for hire fleets and mobile installations.
Hoist compatibility — eye-bolt vs hook vs lug mount
The trolley has a lifting attachment point at its base — an eye, hook, or threaded lug. The hoist suspends from this attachment. The compatibility issue is matching the hoist's top-of-hoist fitting to the trolley's attachment type.
| Trolley attachment | Compatible hoist top fitting | Notes |
|---|---|---|
| Lifting eye / D-ring | Hoist top hook | Most common combination. Hoist hook latches into the eye. |
| Threaded lug | Hoist top eye / hoist mounting plate | Bolt-through connection. Common on electric hoists and motorised trolleys. |
| Integrated hook | Hoist top eye | Trolley has its own hook hanging down; hoist eye latches in. |
| Pin mount | Hoist top yoke | Pin-and-cotter or pin-and-snap-ring. Common on heavy-duty rigging. |
From r/Rigging: practitioners regularly post compatibility questions when swapping a chain block for an electric hoist on an existing trolley. The chain block typically attaches via top hook to a trolley D-ring; the electric hoist often expects a different mount (lug, mounting plate, or pin). Don't assume drop-in compatibility — check the hoist's top-of-hoist specification against the trolley's attachment type before purchase.
End-stops and beam terminations
The single most-overlooked safety detail on monorail beam installations: end-stops. The trolley must be physically prevented from rolling off the end of the beam. AS 1418.2 mandates end-stops at both ends of the beam to arrest trolley travel.
Acceptable end-stops include:
- Welded steel angle — angle iron welded to the bottom flange at the beam end, sized to clear the trolley wheels but contact the trolley side plates.
- Bolted-on steel plate — plate bolted through the beam web with a vertical face that contacts the trolley body.
- Beam end plate — full plate welded across the beam end (typical for purpose-fabricated monorails).
- Buffer block — rubber or polyurethane buffer for production installations where the trolley may impact the end-stop frequently under power.
End-stops are not optional. A runaway trolley dropping off the end of a beam with a load attached is a major workplace incident. Check your existing installation; if there are no end-stops, fit them before the next lift.
Inspection regime — AS 2550.10
Beam trolleys are lifting equipment under AS 2550.10 and require ongoing inspection:
- Before each shift / first use — visual check by operator: wheel rotation, side-plate adjustment locked, no visible damage to wheels or frame, attachment point intact, hand chain (if geared) not knotted or twisted.
- Monthly — documented visual inspection by competent person: wheel wear (no visible flat-spotting), side plate clearance still correct, geared mechanism operating smoothly, no rust pitting or crack indications on load-bearing components.
- Annual — competent-person inspection with documented register entry: as monthly plus removal-from-beam check, dimensional measurement of wear indicators, load-bearing component inspection per AS 2550.10 schedule.
- Proof-load retest — required if the trolley has been involved in an overload incident, dropped from height, or otherwise potentially damaged. Retest to 125 percent or 150 percent of rated capacity (per manufacturer spec) by certified test facility.
Lifting equipment register entries should record date, inspector, findings, and corrective actions. Failed inspection items take the trolley out of service until repaired or replaced.
Common mistakes — 9 forum-validated traps
| Mistake | Why it fails | Fix |
|---|---|---|
| Buying trolley before checking beam flange width | Trolley may not adjust to flange width; 99% of trolleys cap at 203 mm | Measure flange first, then size trolley |
| Installing trolley on residential beam without engineering review | Roof beams sized for distributed gravity load, not concentrated trolley point load | Free-standing gantry crane or purpose-installed lifting beam instead |
| Trolley capacity equal to lifted load (no margin for hoist + rigging) | Hoist mass + rigging mass adds to trolley load; exceeds WLL | Trolley WLL = lifted load + hoist mass + rigging mass + 10–20% margin |
| Tapered-flange trolley on parallel-flange beam (or vice versa) | Wheels sit unevenly; load concentrates on wheel edge | Match trolley wheel profile to beam flange type (UB vs UC) |
| Side-plate spacing too tight | Trolley jams under load; wheels can't roll freely | ~6 mm clearance wider than flange (industry rule of thumb) |
| Side-plate spacing too loose | Trolley can lift off flange under shock loading or beam camber | ~6 mm clearance is the design ceiling |
| No end-stops at beam ends | Trolley can roll off the end with load attached | Welded angle / bolted plate / buffer block mandatory per AS 1418.2 |
| Hoist attachment type mismatch (lug/eye/hook confusion) | Hoist won't connect properly to trolley; improvised connections fail | Confirm trolley attachment matches hoist top-fitting before purchase |
| Skipping monthly inspection / no proof-load retest after incident | Wear and damage go unnoticed; AS 2550.10 compliance fails | Documented monthly visual + annual competent-person + proof-load after incident |

AIMS selection checklist — 8 pre-purchase questions
- What is the beam type and bottom flange width? Measure flange edge-to-edge. Check for taper (UB vs UC). Confirm width is within trolley adjustment range.
- Has the beam been engineered for a trolley point load? Beam capacity tables assume uniform load; trolley point load may reduce effective capacity 30–50%. Engineering review essential for serious installations.
- What is the maximum lifted load + hoist + rigging weight? Trolley WLL must exceed combined weight by 10–20% margin.
- Push, geared or electric travel? Light + short + infrequent = push. Heavy + long + precise = geared. Production + frequent = electric.
- Workshop ceiling height? Low-ceiling workshops (2.7–3.6 m) benefit from close-headroom trolleys.
- Hoist top-fitting type? Lifting eye / hook / lug / pin. Match trolley attachment to hoist top-of-hoist.
- End-stops at both beam ends? Welded angle / bolted plate / buffer block per AS 1418.2.
- Inspection register set up? Monthly visual + annual competent-person + proof-load retest after incident per AS 2550.10.

Frequently Asked Questions
What is the difference between a beam clamp and a beam trolley?
A beam clamp is a static attachment that bolts, screws or wedge-clamps onto a beam flange and stays in place; the hoist hangs from the clamp's lifting eye. A beam trolley is wheeled and travels along the bottom flange of the beam, allowing the suspended load to be moved horizontally as well as lifted vertically. Choose a clamp for single-point lifts; choose a trolley when the load needs to move along the beam. See the Beam Clamp Guide for the static option.
What is the difference between a push trolley and a geared trolley?
Push trolleys are moved manually by pushing the suspended load — the trolley wheels roll free. Best for light loads (up to 2–3 T), short travel and infrequent use. Geared trolleys use a hand chain that rotates a gear wheel to drive the trolley along the beam with mechanical advantage (20:1 to 40:1 typical). Best for heavier loads, longer travel, precise positioning and reduced operator fatigue. Geared is the workshop default for 3 T and above; push is cost-effective for lighter applications.
How do I size a beam trolley to my beam?
Measure the bottom flange width of the beam edge-to-edge. Most AU girder trolleys adjust within ranges like 64–152 mm (entry), 64–203 mm (1T standard), 88–203 mm (2–3T), 102–305 mm (3–5T) and 114–305 mm (5–10T). Plan around the trolley flange capacity at the start — 99 percent of standard trolleys cap at 203 mm (8 inches) flange. Side-plate spacing should be set roughly 6 mm wider than the flange to allow free wheel rotation without binding.
Can I install a beam trolley on my garage roof beam?
Almost never advisable without a structural engineer's review. Residential ceiling and roof beams are sized to support distributed gravity load (the roof, snow, or floor above) and are not rated for concentrated point loads from a trolley plus hoist plus lifted load hanging below. The practical alternatives are a free-standing gantry crane (mobile, no overhead structure required) or a purpose-installed lifting beam engineered for the application. r/Homebuilding direct: "That beam is designed to carry the load above, and probably [not rated for trolley point load]."
What is the WLL of a beam trolley?
Working Load Limit is the maximum static load the trolley wheels and frame are rated to carry — including the hoist mass, the rigging mass (slings, shackles, hooks) and the lifted load. AU standard practice is to size the trolley WLL at least 10–20 percent above the combined working weight. Beaver, Austlift, Garrick Herbert and Pacific Hoists all ship with proof-load test certification at 150 percent of rated WLL per AS 1418.2 / AS 4991:2004 requirements.
What is a close-headroom girder trolley?
Close-headroom trolleys integrate the wheels and hoist attachment into a more compact vertical profile, reducing the "headroom" dimension between the bottom of the beam and the underside of the trolley where the hoist hangs. The reduction is typically 30–50 mm, gaining the same in lifting height — valuable in low-ceiling workshops (2.7–3.6 m). The Beaver Close Headroom Geared Girder Trolley is the AIMS workshop standard. Cost is 10–15 percent higher than standard trolleys at the same capacity.
What is the difference between a girder trolley and a beam trolley?
The terms are interchangeable in AU industry. "Girder trolley" is the more common term in formal lifting equipment classification (used by Beaver, Austlift, Garrick Herbert in product naming). "Beam trolley" is more common in workshop and US-influenced trade vernacular. Both refer to the same product class: a wheeled trolley that clamps the bottom flange of a structural beam and carries a hoist.
How do I attach a hoist to a beam trolley?
The trolley has a lifting attachment point at its base — an eye, D-ring, threaded lug, integrated hook or pin mount. Match the trolley attachment to the hoist's top-of-hoist fitting. Most common combinations: hoist top hook + trolley D-ring (chain blocks), or hoist top eye + trolley lug (electric hoists). Don't assume drop-in compatibility — confirm the specs before purchase. r/Rigging regularly sees compatibility questions when swapping chain blocks for electric hoists on existing trolleys.
What is a Universal Beam vs Universal Column?
In AU structural steel, Universal Beams (UB) have a tapered (sloped) lower surface on the bottom flange — thicker at the web junction, thinner at the edge. Universal Columns (UC) have parallel flanges — flat both top and bottom of the flange. UB sizes are 100UB to 610UB (web depth in mm); UC sizes are 100UC to 310UC. Trolley wheel profiles are designed for one or the other — check the trolley spec against the beam type. American Standard (S-shape) beams are tapered like UB; W-shape beams are parallel like UC.
What are end-stops on a beam trolley?
End-stops are physical barriers at each end of the beam that prevent the trolley from rolling off. AS 1418.2 mandates end-stops at both ends of the beam. Acceptable forms include welded steel angle, bolted-on steel plate, beam end plate, or rubber/polyurethane buffer block (for production installations). End-stops are not optional — a runaway trolley dropping off the beam with a load attached is a major workplace incident. Check your installation; if no end-stops, fit them before the next lift.
How often should a beam trolley be inspected?
AS 2550.10 sets the inspection regime: before-shift visual check by operator; documented monthly inspection by competent person (wheel wear, side-plate adjustment, geared mechanism, no rust/crack indications); documented annual competent-person inspection with register entry; proof-load retest after any overload incident or potential damage. Maintain a lifting equipment register recording each inspection, date, inspector, findings and corrective actions.
Can a beam trolley travel around a curved beam?
Standard girder trolleys are designed for straight-beam travel. Some specialty trolleys can negotiate gentle curves (typical minimum radius 1.0–1.5 m) but require trolley spec confirmation. Tight curves or right-angle beam intersections require dedicated curved-track monorail systems or transfer mechanisms — specialty engineering, not off-the-shelf. For most AU workshops, the beam runs straight and the standard girder trolley handles the application.
What is the proof load on a beam trolley?
AU industry standard proof-load testing is 150 percent of rated Working Load Limit. Beaver girder trolleys ship with documented proof-load test certification at this level. Pacific Hoists, Austlift and Garrick Herbert carry equivalent proof-load certification. Always retain the certification with your lifting equipment register — it's part of the AS 4991 / AS 1418.2 compliance documentation.
What is CPCCLDG3001?
CPCCLDG3001 is the AU national dogging licence — the Certificate of Dogging required for workers who direct load placement and movement on lifting equipment, including trolley-borne hoists. AU workplaces operating beam trolley + hoist systems for commercial lifting require licensed doggers for load direction. Self-contained workshop use within a small business may not require formal dogging certification, but understanding the principles (load assessment, signal communication, exclusion zones) is universally good practice.
Where do I buy a beam trolley in Australia?
AIMS Industrial stocks beam and girder trolleys across Beaver (Bunzl-owned AU industrial standard), Austlift, Garrick Herbert and Pacific Hoists. See the lifting equipment collection and the dedicated Pacific Hoists range. For specialty requirements (custom 15-30 T trolleys, curved monorail systems, motorised cross-traversing), AIMS sources through supplier network — contact the team with the beam specification and load requirements.
