10% of their rated WLL limit. William Hackett L4 lever hoists are assembled, chained and tested in the UK to the height of lift specified by the end user. Careful consideration should be given to the headroom required to lift the load and the position of the operator before specifying the length of load chain and the hoist model.
Pre-use checks Before the lever hoist is issued from the designated storage location a competent person must ensure that the appropriate certification is in place for the hoist. Safe use instructions should be made available. Possession of the relevant certification does not absolve the user from his responsibility to carry out pre-use inspections.

Do not attempt lifting operations unless you understand the use of the equipment, the lifting and slinging procedures and you have been suitably trained. William Hackett L4 lever hoists are not designed for lifting people and should not be used for that purpose. Use appropriate personal protective equipment (PPE).
Storage and Control Procedures The equipment should ideally be stored in a purpose designed facility where it can be kept secure from unauthorised use. A responsible person should control the issue and receipt of all lifting appliances and accessories, and a system to manage statutory inspections should be in place. Storage would normally be on suitable racks within a container a manner that prevents accidental mechanical damage and where the load chains are clear from the ground.
When planning a lifting operation using a lever hoist or selecting a lever hoist for a lift, the light load limitation of the braking mechanism should be recognised. The William Hackett WH-L4 lever hoist is tested and certified to have a light load capability at 2% of the lever hoist rated capacity, but it is not recommended to use a lever hoist at below 10% of the rated capacity, but it is not recommended to use a lever hoist at below 10% of the rated capacity.
