Beaver Double Hand Operated Sheave Block with Swivel Hook 63 mm, WLL 250 kg (551063)

Beaver double hand operated sheave blocks with swivel hook are double sheave rigging blocks (pulley blocks) with an integrated swivel hook and safety latch (manufacturer-stated). Beaver describes the double block as a hand operated double sheave block built for heavy-duty use, for controlled lifting and manoeuvring of loads, and states compliance with AS 2089 (manufacturer-stated). This listing carries 2 sizes, 63 to 76 mm sheave diameter, for 5 to 6 mm wire rope or 10 to 12 mm fibre rope, with WLLs of 250 kg to 250 kg (manufacturer-stated). Beaver's range also lists 89, 102, 114, 127 and 152 mm (551089, 551102, 551114, 551127, 551152).

The swivel hook attaches the block to an anchor point, and the sheave turns the rope or wire rope through the block to change the direction of the pull. Beaver does not state the sheave or hook material, the finish or the bearing type, and gives no installation or reeving instructions.

Working load limit and use

Beaver lists a working load limit (WLL) for each size (manufacturer-stated). Beaver does not publish the basis of the WLL, a proof load, the rating of the swivel hook or bearing details. The pull on the rope and the load carried by the block are not the same thing, so check the WLL against the total load the block will carry, including the pull from each rope leg. 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.

Key specifications

Codes, sizes, dimensions and working load limits are from Beaver's Materials Handling Technical Manual (Vol. 4) and the Beaver website. Beaver does not define dimensions B and E. G is the sheave diameter. Beaver sells the blocks singly (unit of measure: each).

Selecting the right option

Choose the sheave diameter and rope size to suit the rope you are using, then check the WLL against the load the block will carry. Beaver lists, for example, 5 mm wire rope or 10 mm fibre rope for the 63 mm size.
