R&M Materials Handling, Inc. reserves the right to alter or amend the above information without notice.
The current should be in balance in all phases and may not exceed the ratings for the motor. Check the
current at both hoisting speeds.
7.2.2 Inspection of running temperature.
If the thermal protection halts hoisting prematurely, identify the reason for overheating before continuing
the commissioning tests.
7.2.3 Inspection of travelling machinery.
• Check that the acceleration and braking motions operate smoothly.
• Run the trolley at least 3…5 times over the whole length of the girder. Remove the paint coming loose
from the runway of the trolley.
7.3 Inspections with overload, 110…125% of the rated load of the hoist.
7.3.1 Inspection of overload protection
• Check that the overload protection mechanism operates with an overload.
The overload protection must prevent hoisting motion when the load exceeds the trigger load for the
overload protection mechanism that is stated in the test drive. If the hoist is provided with a condition-
monitoring unit, refer to the separate operating instructions for commissioning the condition-monitoring
unit.
7.3.2 Inspection of brake operation.
• Lower the load in slow speed and stop. Ensure that the brake is able to stop the motion adequately.
7.3.3 Inspection of rope
• Ensure that the rope has not slipped in the rope anchorage by comparing the measures with the
stated measures in the table. (see section Rope anchorage)
7.4 After the inspections.
7.4.1 Cleaning
• Check that all tools and materials used during installation are removed from the hoist and track.
7.4.2 User training
• Ensure that the hoist operator and supervision personnel are aware of the need for user training.
#
The authorized service organization of the hoist manufacturer can arrange user training by
separate agreement.
7.4.3 Hand-over documents
• Check the documents delivered with the hoist. Ensure that entries in the documents are properly
recorded and that the reference data in the documentation matches that on the type rating plates.
#
Compile a commissioning log for the hoist and keep it with the other documentation for the hoist.
