Together with the wire rope, blocks are the connection between the load to be lifted and the lifting device. Applications Van Beest offers a wide range of blocks, from single sheave snatch blocks to multiple-sheave malleable iron blocks for use with wire or fibre rope. Blocks are suited for head loads ranging from 0.4 up to 15 tons. Other types of blocks can be offered upon special request. Range There are different types of blocks with their specific designs to suit a particular purpose. Some types are equipped with bronze bushes while other types have conical roller bearings depending on frequency of use and line speed. Snatch blocks allow the wire rope to be attached easily by opening up the block instead of threading the wire rope through the block. All types carry the following markings: • Working Load Limit; • manufacturer’s identification symbol (GP); • traceability code; • CE. Design Blocks can be either painted or electro-galvanized. Finish All blocks can be supplied with test certificates upon request. Certification The basic objective of any lifting operation is to move the load to the desired location and land it safely, efficiently and without damage to the load, the equipment used and/or the surrounding area. The following point must be observed: • Do not attempt any lifting operation unless you have been trained in the use of the equipment concerned; Blocks should be inspected before use to ensure that: • all markings are legible; • blocks are free from nicks, gouges and cracks; • the sheaves are functional and rotate easily; • a block with the correct Working Load Limit has been selected with respect to the load being moved and the wire rope being used; • the block is never side loaded but strictly used for straight or in-line pull; • the Working Load Limit applies to static loads only, shock loading must be taken into account when selecting a block; • always make sure that the hook, eye or shackle of the block is supporting the load correctly; • blocks may not be heat treated as this may affect their Working Load Limit; • never repair or reshape a block by welding, heating or bending as this may affect the Working Load Limit. It is required that the products are regularly inspected and that the inspection should take place in accordance with the safety standards given in the country of use. This is required because the products in use may be affected by wear, misuse, overloading etc. with a consequence of deformation and alteration of the material structure. Inspection should take place at least every six months and even more frequently when the blocks are used in severe operating conditions. Instructions for use
