20 COMMISSIONING
Before taking the hoist back into operation, the inspections and adjustments listed in “Installation and
Commissioning Manual for Hoist” must first be carried out.
A list of necessary inspections are described as follows. See “Installation and Commissioning for Hoist” for more
detailed information.
Inspections without load
Verify that the connections of all electrical equipment to the panels are secure and wiring connections are tight
Inspect the push button controller and verify the correction directions of the hoist
Check the operation and condition of the emergency stop button
Listen for normal operating sounds
Check the operation of the hoisting limit switch, and adjust accordingly
Inspect the wire rope for any defects
Check the operation of the traveling limit switches of both the trolley and the bridge, and adjust accordingly
Check that the trolley buffer hits the center of the end stop. Check also that the trolley buffers are able to make
contact with the runway end stops or the buffers of another trolley
Inspect the hook and sheaves for proper rotation / operation
Check the operation of the overload protection (CID in use): lift a known load and verify that the load is
measured with +/- 5% accuracy
Inspect that the trolley is operating properly on the bridge
Verify the hoisting brake operation
If more than one hoist on the crane, check that the hoist selection is operating properly.
Setting in a new wire rope
A new wire rope shall be taken into use with a load that is approx. 10% of the nominal load. This load is lifted to the
total lifting height for 5 to 10 times. Make sure that the hook is not rotating while lifting.
Inspections with test load, 100% of the rated load of the hoist
Measure the power supply
Inspect the brake operation
Inspect the traveling machinery.
Inspections with overload, 110…125% of the rated load of the hoist
Inspect the overload protection mechanism
Inspect the brake operation
Inspect the wire rope fastenings.
Tasks after the inspection phases:
Cleaning (check that all tools and materials used during the installation and commissioning are removed from
the hoist and track)
Inform the customer on the requirements of having operators trained in safe and efficient crane operation
Handover documents.
