Pacific PCB303L Chain Block with Overload Protection, 0.5 tonne (500kg), 3m Lift

The Pacific Chain Block with Overload Protection is the overload protection version of the Pacific Chain Block, with part numbers that end in L. The catalogue lists the range from 0.5 tonne to 10 tonne and names a patented overload limiting device as an option (excluding 250kg capacity) (manufacturer-stated). There are 6 models from 0.5 tonne to 5 tonne, with a lift of 3m or 6m.

The catalogue does not say what load the overload limiting device trips at or how it is set, so no trip figure is published. It lists the same key features as the standard Pacific Chain Block: a brake lockout mechanism, European zinc-plated grade 80 load chain, a high-strength end stop with a secondary end anchor and encapsulated bearings (manufacturer-stated).

For each model the catalogue gives the rated capacity, lift, hand chain drop, chain falls, load chain size and net weight. The 3m lift models have a 2m hand chain drop and the 6m lift model a 5m drop.

The catalogue lists this range against Australian Standard AS1418.2 (manufacturer-stated). No certificate or test report is published for this product: if your site needs proof of compliance, ask for the maker's documents before you buy.

Common specifications

Key specifications

Figures are as printed in the Pacific Hoists catalogue (manufacturer-stated). Hand chain drop and lift are in metres, load chain size in millimetres.

Selecting the right option

Choose the capacity on your heaviest lift and keep the load inside the rated capacity on the table, then choose the lift for the height you need. An overload limiting device does not replace the rated capacity: plan the lift to the rated capacity, not to the point where the device acts. This listing carries the 6m lift in the 1 tonne size only (PCB316L); the other sizes are 3m. Lifting equipment must be used within its rated capacity, inspected before each use, and selected and used in line with your site lifting procedure and the applicable standards and regulations. Do not use it to lift or lower people. If you are unsure what suits your lift, speak to a qualified rigger before ordering.
