1.2 Installation
1.2.1 Support
•
Make sure the supporting structure is designed to withstand the loads and forces imposed by the
hoist/trolley.
•
Make sure trolley stops are installed at the limits of trolley travel. Trolley stops shall not be used as a
continuing means of stopping the trolley, if a trolley is used.
1.2.2 Start-up Check Points
Before operating the new unit, carry out the following start-up procedures:
•
Read the attached WARNING tag or other legends affixed to the unit that includes cautionary
language AGAINST:
1. Lifting more than rated load;
2. Operating hoist with twisted, kinked, or damaged chain;
3. Operating damaged or malfunctioning hoist;
4. Lifting people or loads over people;
5. Operating hoist with other than manual power;
6. Removing or obscuring warning information.
•
With a brush, oil the chain generously along the entire length.
•
Make sure that the load chain is not twisted or kinked. If so, untwist the load chain before using.
•
Grease the swivel joints of the hooks.
• Make sure the trolley wheels have proper spacing in relation to the beam flange, if a trolley is used.
•
Without a load, carry out several lifting and lowering operations using the entire length of the load
chain.
•
With a load, carry out several lifting and lowering operations observing the operation of the load
chain and sprocket. The load chain should feed smoothly into and away from the sprocket.
•
Check to see that all functional operating mechanisms including the mechanical brake are operating
correctly.
1.3 Operating Procedures
The hoist lifts and lowers the rated load in a controlled manner when a manual force is applied to the hand
chain. The hoist is equipped with a brake, which sustains and controls the rated load when the hoist is being
operated in either direction.
The manual chain hoists are for lifting and lowering. The use of the hoists for pulling or side pulling is not
allowed because the chain guides and positioning of other parts are not designed for this type of operation.
