Hoist Selection
Selecting the correct Hackett WH-L4 lever hoist
William Hackett L4 lever hoists are manufactured in accordance with BS EN 13157:2004+A1:2009, ASME
B30.21-2014, AS1418.2-1997 and SANS 1636:2-2007.
William Hackett L4 lever hoists are assembled, chained and tested in the UK to the height of lift specified by the
end user.
The configuration of lever hoist assemblies are demonstrated on previous page and are in accordance with the
product specification, dimensions and safe working load (SWL) recorded in Table 1.
William Hackett L4 lever hoists can be used within an operating temperature range of -40°C to +55°C.
In accordance with statutory requirements (e.g. The Lifting Operations and Lifting Equipment Regulations
1998), all lifts using chain block assemblies should be planned by a competent person; require risk
assessment and the production of a task method statement; and be subject to execution by suitably trained
operatives under the supervision of a responsible person. The specification of the lever hoist assemblies
required to achieve a safe lifting operation must be determined by a competent person.
Careful consideration should be given to the mass of the load being lifted and any dynamic factors that may
be likely to affect the load on the hoist. Select the hoist capacity equal to or greater than the load. Ideally lever
hoists should not be used to lift loads below 10% of their rated WLL limit.
It is not intended that the recommendations in this manual take precedence over existing plant safety rules and
regulations or OSHA regulations. In the event that conflict exists between a rule set forth in this publication and
a similar rule already set by an individual company, the more stringent of the two should take precedence.
A thorough study of the information in this manual should provide a better understanding of safe operating
procedures and afford a greater margin of safety for people and equipment.
In accordance with statutory requirements (e.g. The Lifting Operations and Lifting Equipment Regulations
1998), all lifts using chain block assemblies should be planned by a competent person; require risk
assessment and the production of a task method statement; and be subject to execution by suitably trained
operatives under the supervision of a responsible person. The specification of the lever hoist assemblies
required to achieve a safe lifting operation must be determined by a competent person.

Hoist Attachment / Mounting
Check the correct engagement of the top and bottom hooks. The hooks should be free to articulate fully when
engaged with the load attachment points without overcrowding or point loading.
Ensure that the suspension structure has sufficient load bearing strength and capacity to support the load
being lifted.
If more than one hoist is to be used in a fleeting arrangement, load attachment equipment should be chosen
that allows for the angles of the lift.
Do not use the load chain of the lever hoist as a chain sling. The lever hoist is a lifting appliance and suitable
lifting accessories should be incorporated into the lift plan to facilitate attachment to the load.
Make sure that the load chain is free from any twists or knotting. In the case of multi-fall lever hoists ensure that
the bottom hook has not been capsized causing chain twist.

7
Pre-use Procedure
Before issue from the designated storage location the certification supplied with the lever hoist should be
confirmed as within date.
The label on the hoist should be fully legible and it should correspond with the relevant certification.
Conducting thorough and consistent checks on a lever hoist immediately prior to use will help identify problems
due to accidental damage, internal corrosion, brake contamination or inappropriate storage. Recommended
checks include:
1. If necessary the hoist should be cleaned before inspection.
2. Name Plate – details clear and visible
3. Hook latches in good working order
4. Is the Load chain worn or damaged? In particular attention should be given to the wear which occurs on the
bearing surfaces inside the links and to damage in the form of bent, notched, stretched, or corroded links
and the chain should move freely.
5. Obvious signs of hooks opening out increase in throat opening or any other form of distortion in the hooks
or suspension fittings.
6. Top and bottom hooks free to rotate with no load applied.
7. With no load applied turning the grip ring clockwise should produce a clear and positive clicking sound as
the brake ratchet activates.
8. On multiple fall hoists check that all chain sheaves are free to rotate whilst no load is applied.
9. Check all fixings are in place and in good condition, split pins or nyloc nuts.
10. Obvious signs of damage to the hoist slack end chain anchor.
11. General damage to the hoist body, this can be an indicator of neglect throughout the hoist.
12. The load chain wheel should be checked for damage or debris
13. Chain guides and strippers should be free of debris and in good condition.
14. Operating instructions should be available.
If any of these points are not satisfied the lever hoist MUST NOT be used.

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 L4 lever hoists are not designed for lifting people and should not be used for that purpose.
Use appropriate personal protective equipment (PPE).
Always inspect the lever hoist prior to use, and if any damage is apparent the hoist should be quarantined for
inspection by a competent person. Labels should clearly show the identification and other data for the hoist.
Check the correct engagement of the top and bottom hooks.
Ensure that the suspension structure has sufficient load bearing strength and capacity to support the load.
Do not use the lever hoist as a chain sling; it is a lifting appliance and suitable lifting accessories should
be incorporated into the lift plan to facilitate a safe lifting operation.
If more than one lever hoist is to be used, refer to fleeting instructions on page 9..
Establish a clearly defined zone around the area of the lifting operation.
Always stand aside from the load when operating the hoist and ensure that no one enters the lift zone
unintentionally during the lifting operation.
Ensure that the load and hand chains are not twisted, particular care should be taken when using multi-fall
hoists.
During the lift the load and hand chains should be straight and should not contact any angles or edges.
Take the load steadily and avoid shock loads.
Do not expose lever hoist assemblies, chain slings and components to chemicals or corrosive solutions
(whether immersed in such solutions or used in atmospheres in which fumes are present), particularly acidic or
strongly alkaline environments without consulting the supplier or manufacturer.
Do not leave suspended loads unattended. In an emergency cordon off the working area and establish safe
exclusion zones.
Never return a damaged lever hoist to stores; it should be reported to a competent person.

9
Fleeting Advice
The following guidance is for the safe use of manual lever hoists when being used away from the vertical
(between 0° and 45°), and when lifting and moving a load in conjunction with additional manual lever hoists
(known as fleeting or cross hauling). These lifting operations should be assessed and planned by a competent
person.
Top Hook Suspension - the suspension point must have sufficient clearance to allow the top hook to articulate
within it.
The suspension point must have a SWL equal to or greater than the load to be lifted.
Bottom Hook Attachment - the attachment point onto the load must have sufficient clearance to allow the
bottom hook to articulate within it.
Make sure that the load chain is free from any twists or knotting; and in respect of multi-fall manual lever hoists
that the bottom hook has not been capsized.
Check the area around the load and assess if the load will move between lever hoists during the lifting
operation.
Ensure that both the top hook, bottom hook, lever hoist carcass, and load chain are all in line.
When using multiple manual lever hoists to lift and move a single load, the load should not exceed the SWL of
any individual hoist being used for that lift.

10
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.
The load chain should be dried and wrapped around the hoist, not left on the floor
During transport to the worksite and whilst in store at the worksite, the equipment should be protected from
exposure to any conditions which may affect its ability to operate safely. In particular, it should be protected
from exposure to:
• water/sea water;
• temperatures higher than can be comfortably tolerated by the hand
• temperatures below freezing point
• solvents
• corrosive chemicals or fumes
• grit, sand and wind-blown dust.
Any defects should be reported to the responsible person and damaged hoists should be quarantined.
Duty holders and actual users of lifting equipment, including hoists and associated components can obtain
more detailed information and guidance on safe use and compliance with statutory requirements from the
following publications;
HSE Publication L22 (2014) Safe Use of Work Equipment.
HSE Publication L113 (2014) Safe Use of Lifting Equipment.
