• Listen to the operating sounds during lifting or traveling movements. Pay attention to
unusual noises such as squealing.
• Check that the chain hoist runs smoothly and without any strong vibration.
NOTE
If any defects or abnormalities are detected during the commissioning, they must be
investigated and corrected. Investigate and correct the defects and abnormalities
according to the instructions that are relevant to the component in question.
7.
Check the slipping clutch operation
• Check that the slipping clutch mechanism works correctly. When the torque caused by
load (1) exceeds the designed lifting limit, the clutch discs (2) should begin to slip,
preventing the lifting movement.
8.
Check the brake operation
Check that the hoisting brake operates correctly in both upward and downward directions.
The braking distance is normal when it is two chain links or less.
5.3.4
Testing the hoist with test load
Before starting to use the product, check that it is used as intended in all possible applications.
Check that the product is operated with only the maximum permissible load. Check the
operation of the safety devices, for example, by lifting an overload. If the product is not used
correctly, check the behavior of the product.
1.
Perform the load tests
• Test the product with dynamic and static load tests. Perform the dynamic tests with 110%
of the rated capacity. Perform the static tests with 125% of the rated capacity.
NOTE
The test load must be securely fastened and properly balanced.
NOTE
Make sure that the hook does not turn around while lifting.
2.
Measure the power supply
• Check that the voltage is over the required minimum value (normally -5 %) under 100%
load.
3.
Check the brake operation
