Verify the condition and operation of hoisting limit switches.
Operate the hoist in the up direction and slowly drive to the Up Limit
Switch Activation point. Check that it works.
Run the hook block down at a short distance and drive at high speed
and check if the Slow Down Up Limit activates to override the high-
speed command to slow down the speed before the Up Limit
activates.
Operate the hoist in the down direction and drive to the Down Limit
Switch Activation point.
Test the Hook Limit by hand actuation.
Adjust or replace parts as required.

Verify Up Limit Distance.
Verify the Up Limit Distance to the frame of the trolley. It is important
to adjust the C dimension according to the specification, to minimize
rope and sheave wear.

Verify Down Limit Distance.
When the hook block is in the Down Limit Switch Activation point,
verify that there is a minimum number of wraps of rope on the drum
according to the standards (the absolute minimum is two full turns of a
rope).

Inspect the condition and operation of the overload protector.
Mechanical switch and load sensor overload device:
Test the free movements of mechanical parts.
Test the mechanical overload limit switch by mechanically activating
the switch and checking for a click.
Clean and lubricate lever mechanism.
Verify that the set screw is locked in its place.
When required to confirm calibration, place a test weight of a nominal
load plus 10%. Adjust mechanical overload to stop hoisting at 110% of
capacity.
Replace damaged parts.
Power measurement overload device:
Conduct a test operation of the power measurement overload device
according to the local regulations if necessary.

Verify the operation of the condition monitoring unit.
Test the condition monitoring unit by lifting a known load and verify
that the unit reads the load within 5% accuracy. If not reading
properly, a new calibration of the unit required.
Check for possible error codes and warnings.

Crane runway rail
Inspect the crane runway rail.
• Check the bridge squareness
• Check that both end trucks are working simultaneously in the starting
and the stopping phases
• Monitor for possible sounds of grinding or any unsmooth travel of the
bridge along the runway
• Visually check the straightness
• Check rail fastenings randomly for possible loose connections
• Check the rail for any signs of wear.
