Page 5: Hoist Selection
10% of their rated WLL limit. William Hackett compact 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. -
Page 6: Pre-Use Checks
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. -
Page 7: Operation
Operation Free Chain Adjustment 1. To adjust the chain, position the selector lever in the horizontal neutral position (N). a) In Neutral mode the load chain can be pulled to adjust to the required length, this can be aided by turning the handwheel in the relevant direction. -
Page 8: Safe Use Information
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 compact lever hoists are not designed for lifting people and should not be used for that purpose. -
Page 9: Storage And Control Procedures
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. -
Page 10: Practical Considerations
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 compact 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. -

Apply a light coating of grease to the load sheave 15 and side plate 11 mating surfaces then insert the load sheave into the gear side plate so that the splined side protrudes through the plate. -
Page 25: Functional Checks
Functional checks 1. In neutral with a light progressive pull on both the hook side and slack end load chain, the chain should run freely and smoothly. With a sharp pull on the load chain the hoist brake should activate. 2. -
