Lifting Operations and Lifting Equipment Regulations 1998 and pulley systems and forklift trucks. The regulations apply to all workplaces and all the provisions of the 'Provision and Use of Work Equipment Regulations 1998' also apply to lifting equipment. A safe working load (SWL) should, according to the regulations be marked onto lifting equipment with the relevant SWL being dependent on the configuration of the equipment, accessories for lifting such as eye bolts, lifting magnets and lifting beams should also be marked. The load itself would be based on the maximum load that the equipment can lift safely. Lifting equipment that is designed for lifting people must also
Block and tackle blocks. Frictional losses also mean there is a practical point at which the benefit of adding a further sheave is offset by the incremental increase in friction which would require additional force to be applied in order to lift the load. Too much friction may result in the tackle not allowing the load to be released easily, or by the reduction in force needed to move the load being judged insufficient because undue friction has to be overcome as well. A block which is open or can be opened to engage with a bight, without the necessity to thread the
