The following should be monitored closely after commissioning. The cable stretches when first begin using.
Check that the counterweight for the fall brake is moving
freely up and down. Also, check the wear on plain bearings,
nylon washers and clamp rings for the counterweight,
replace if necessary.
Check position of the counterweight height wise, the
slack rope switch must be located in the middle +-5 mm
of the grove, if not adjust position with the thimble or turnbuckle.
The thimble or turnbuckle is located directly behind the crane cabin manual control panel.
