Beaver Super Buckle Jaw and Jaw with Lock Nuts 12 x 305, WLL 1 t (322412)

Beaver super buckles are rated jaw and jaw turnbuckles with lock nuts for straight, in-line tensioning with wire rope and chain assemblies. Beaver lists a working load limit (WLL) for each size and states Federal Specification FF-T-791 (Type 1, Form 1), a US specification, for this product (manufacturer-stated). Beaver states no Australian Standard for it. This listing carries five sizes with WLLs of 1, 1.59, 2.36, 3.26, 4.54 tonnes (manufacturer-stated).

Beaver describes these turnbuckles as made from Grade P high tensile steel, quenched and tempered, with a forged, hot dip galvanised finish suitable for outdoor use, in imperial sizes, and as suitable for industrial lifting purposes (manufacturer-stated). Beaver lists the size as, for example, 12 x 305 under an inches heading and does not define the figures. They match a 12 mm (1/2 in) diameter and a 305 mm (12 in) length.

Working load limit and use

Beaver states its rated rigging hardware has a working load limit (WLL) and is rated for lifting applications, and that the rated load depends on the end fittings and thread (manufacturer-stated). Do not use the WLL as a guide for a different configuration, such as a hook end, which Beaver says has reduced capacity. Lifting equipment must be used within its marked working load limit (WLL), inspected before each use, and selected and used in line with your site lifting procedure and the relevant Australian Standards. If you are unsure what suits your lift, contact AIMS or a qualified rigger before ordering.

Securing the end fittings

Beaver's manual says turnbuckle end fittings must be secured, and gives this guidance (manufacturer-stated): to resist vibration, lock using wire; locknuts are not effective and add greatly to the load in the screw thread; when tightening, apply only the torque used for a bolt of equal size.

Key specifications

Codes, sizes, working load limits, dimensions (in millimetres), weights and pack quantities are from Beaver's Materials Handling Technical Manual (Vol. 4). Beaver does not define the dimension letters. Where the Beaver website differs, the manual value is shown. Beaver sells the super buckles singly (unit of measure: each).

Selecting the right option

Choose the size by the working load limit your application needs, then check the dimensions and the end fittings against your rigging. A qualified rigger should confirm the selection for any lifting application.
