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 tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a. This is an example of the Luff tackle. The decision of which to use depends on pragmatic considerations for the total ergonomics of working with a particular situation. Reeving to advantage is the most efficient use of equipment and resources. For example, if the load is to be hauled parallel to the ground, reeving to advantage enables the pulling force to be in the direction of the load movement, allowing obstacles to be managed more easily. Reeving to disadvantage adds an extra
