4 WH-C4 CHAIN HOIST USER MANUAL
Hoist Selection
In accordance with statutory requirements (e.g. The Lifting Operations and Lifting Equipment Regulations 1998), all lifts using chain hoist 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 chain hoist assemblies required to achieve a safe lifting operation must be determined by a competent person.
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.
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 chain hoists should not be used to lift loads below 10% of their rated WLL limit.
William Hackett C4 chain 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 the load chain and the hoist model.
William Hackett C4 chain hoists are designed for industrial applications in both indoor and outdoor plus topside marine environments.
William Hackett C4 chain hoists are available in specialised versions to suit hazardous environments. The C4 Atex hoist is suitable for spark sensitive use and the SS-C4 is corrosion resistant and suitable for subsea use.
William Hackett C4 chain hoists can be used within an operating temperature range of -20°C to +120°C.
William Hackett C4 hoists are suitable for fleeting lifting.
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.
The configuration of chain hoist assemblies are demonstrated on page 4, and are in accordance with the product specification, dimensions and working load limit (WLL) recorded in Table 1 (also on page 4).
WH-C4 CHAIN HOIST USER MANUAL 5
Pre-use checks
Before the chain 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.
Conducting thorough and consistent checks on a chain hoist immediately prior to use will help identify problems due to accidental damage, internal corrosion, brake contamination or inappropriate storage. Points to check before each period of use are: · If necessary, the hoist should be cleaned
before inspection. · Name Plate details clear and visible. · Hook latches in good working order · Is the load chain worn or damaged.
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 excessively corroded links and the chain should move freely. · Obvious signs of hooks opening out increase in throat opening or any other form of distortion in the hooks or suspension fittings. · Top and bottom hooks are free to rotate with no load applied. · With no load applied turning the hand chain clockwise should produce a clear and positive clicking sound as the brake ratchet activates.
· On multiple fall hoists check that all chain sheaves are free to rotate whilst no load is applied.
· Check all fixings are in place and in good condition, split pins or nyloc nuts.
· Obvious signs of damage to the hoist slack end chain anchor.
· General damage to the hoist body, this can be an indicator of neglect throughout the hoist.
· The load chain wheel should be checked for damage or debris.
· Chain guides and strippers should be free of debris and in good condition.
If any of these points are not satisfied the hoist MUST NOT be used.

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 C4 chain hoists are not designed for lifting people and should not be used for that purpose.
William Hackett C4 chain hoists are not designed for lifting people and should not be used for that purpose.
Ensure that the load and hand chains are not twisted, particular care should be taken when using multi-fall hoists.
Use appropriate personal protective equipment (PPE).
Check the correct engagement of the top and bottom hooks. The hooks should be free to articulate within the load attachment points without overcrowding.
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, using the hand chain to apply effort. The load is lowered by pulling the hand chain in the opposite direction.
Ensure that the suspension structure has sufficient load bearing strength and capacity to support the load.
Do not use the chain 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 chain hoist is to be used, refer to Appendix 1: General Guidance for Fleeting Lifting at the end of this manual.
Establish a clearly defined zone around the area of the lifting operation.
Do not expose chain hoist assemblies 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 chain hoist to stores; it should be reported to a competent person.
Always stand aside from the load when operating the hoist and ensure that no one enters the lift zone unintentionally during the lifting operation.
WH-C4 CHAIN HOIST USER MANUAL 7
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 in 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. 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. HSE Publication INDG422 (2008) Thorough Examination of Lifting Equipment. HSE Publication L23 (2004) Manual Handling. HSE Publication L25 (2005) Personal Protective Equipment at Work.

Practical considerations
As with any item of lifting equipment, the chain hoist will be specified for a maximum working load limit. This should not be exceeded during any lifting operation. It is important, therefore, when planning a lifting operation that the load to be lifted on the chain hoist is known or has been accurately estimated with an adequate allowance for safety. The possible effects of additional loading, such as friction, should be included when the chain hoist is being selected for the lift.
The design of chain hoists is such that a brake mechanism is used to suspend the load but also requires a load to operate. When planning a lifting operation using a chain hoist or selecting a chain hoist for a lift, the light load limitation of the braking mechanism should be recognised. The William Hackett WH-C4 chain hoist is tested and certified to have a light load capability at 2% of the chain hoist rated capacity, but it is not recommended to use a chain hoist at below 10% of the rated capacity.
applied to a locked brake mechanism – something manufacturers regard as bad practice, potentially resulting in unexpected slippage as the hoist is then operated. If a load is removed from a chain hoist, the chain hoist should be operated to unlock the brake and confirm the hoist is fully functional before the chain hoist is used for another lifting operation.
A chain hoist should be loaded and unloaded using the hand chain. When a load is removed from a chain hoist other than using the hand chain (e.g. by transfer of a load to a surface crane) the brake mechanism will remain locked together. Subsequent loading of the hoist (for example, by the transferring of a load on to the hoist from a surface crane) will result in the load being

brake section then insert through load gear. 6. Install the pinion gears making sure the alignment marks are correctly positioned, apply a liberal
amount of grease to the assembly then secure the gear cover using 3 nylon locking nuts. 7. Turn the hoist over so that the brake side faces upwards then reinstall the top hook, unsure the top
hook pin is fully seated. 8. Install the pawl assemblies lightly greasing the pawl shafts, ensure the pawl springs are secured
correctly, and the circlip is seated firmly in its recess. 9. Install the disc hub #21 by rotating clockwise on to the pinion shaft. 10. Tension the pawls by turning them clockwise against the pawl spring, do not over tension. 11. Fit the lower friction disc, ratchet gear and upper friction disc ensuring the ratchet tooth profile
matches that of the pawls. 12. Install the brake cover #27. 13. Hold the end of the pinion shaft with a set of pliers and wind the load limiter/handwheel down the
pinion shaft in a clockwise direction by hand until the load limiter comes to a stop. 14. Line up the castellated nut with the threaded pinion shaft and fasten by hand in a clockwise direction
until the castellated nut comes into contact with the handwheel or load limiter shim/washer as applicable. Rotate the castellated nut anti-clockwise until one of the castellated slots in the nut aligns with the drilled hole located near the end of the pinion shaft so that a new split pin can be inserted. The drilled hole should align with the first or second available castellated slot. Insert and secure split pin. Ensure the handwheel rotates freely in both a clockwise and anti-clockwise direction. 15. Insert the split pin through both the castellated slot in the nut and the drilled hole of the pinion shaft, ensuring these are aligned. The split pin used should be size 3/32 x 1. The head of the split pin should be seated inside the slot of the castellated nut, with the eye of the split pin sitting in the vertical plane. The top leg of the split pin should be folded over and positioned flat on top of the pinion shaft. The bottom leg should be shortened with a cutting tool and folded down the edge of the castellated nut. Ensure that the legs of the split pin do not interact or interfere with any other components, including the shim/washer. 16. The hoist is now ready for chain installation.
Chain Installation The Chain shall be installed with the weld facing away from the main hoist sheave in a vertical plain.

RAISING THE LOAD To raise load, pull the right side of hand chain (A, Figure 5) so that the wheel turns clockwise. To lower the load, pull left side of hand chain (B, Figure 1) so that wheel turns anti-clockwise. Important: Make sure the hoist has an adequate length of load chain to raise or lower the load in a safe manner. Do not attempt to lower the hoist beyond its limit.
4. Fix the two halves of the speed link together with two 2.4mm x 6mm stainless steel pop rivets.
Figure 1
HAND CHAIN: JOINING AND INSTALLING 1. Cut the required length of 5mm x 25mm hand
chain so that the links at either end plain in the same direction.
Note: The indicated `speed links’ must only be used on hand chain which fully complies with the dimensional detail indicated within this script. The hand chain runs over a specific calibrated pocket wheel and the chain is also calibrated to suit this particular pocket wheel.
LOAD AND WEAR LIMITS
Alloy Steel Chain Carefully inspect the entire load chain. Measure five consecutive links with calipers to measure the length. Check every metre and especially where excessive wear is indicated. Any load chain that shows noticeable deformation or heat influence must be replaced with a new one. Never extend the load chain by welding a second piece to the original.
2. Make sure the chain is not twisted and bring the two ends together.
3. Join the two ends of hooking speed links over each side making sure that the chamfered edge of the speed link is to the outside.
