Testing and Operational Checks
On completion of installation, but before the hoist is put into regular service, the following
procedure should be followed:
1. Check that the hoist is properly installed to either a fixed position or trolley, whichever
applies.
2. If hoist is installed on a trolley, ensure that:
•
The trolley is properly installed on the beam.
•
The stops for the trolley are correctly positioned and securely installed on the beam.
3. Isolate the power supply.
4. Check that all mechanical and electrical joints and connections are tight and secure.
5. Check that all nuts
,
bolts, and split pins (cotter pins) are securely fastened.
6. Confirm proper operation:
•
Before operating, read and become familiar with this manual.
•
Before operating, be sure there are no interferences with the full range of the hoist
(and trolleys) operation.
7. Switch on the power supply.
8. Run lightly, without load, throughout the full operation of the hoist. Check that the hoist runs
smoothly.
9. Check the operation of the hoist brake
and
run under light-load and full-load conditions.
