Crane and Carrier Drive Machinery:
1.
Inspect drive tires for wear and slippage and adjust all spring mounts uniformly at each drive wheel. Tires
should be adjusted with only sufficient pressure to prevent slipping. If wheel pressure is excessive the
crane will not operate properly, and if extreme, the drive motor can be stalled.
2.
Inspect trolley wheels for wear and if equipment' is equipped with lubrication fittings, add any necessary
lubricant.
***NOTE: Avoid over-greasing which can damage bearing seals.
3.
Inspect and test interlocks for proper clearances and freedom of operation.
4.
Inspect current collectors for shoe wear and alignment and adjust if necessary.
5.
Inspect for loose electrical connections or damaged wiring.
6.
Check oil level in gear cases and add a good grade of medium grade machine oil if required.
7.
If equipment is equipped with travel brakes, test operation and adjust if necessary.
Miscellaneous Accessory Equipment:
1.
Inspect all interlocks and crossovers for alignment, clearance and freedom of operation.
2.
If interlocks are motor-operated, check oil level and add a good grade of medium machine oil.
3.
Test the stroke of motor-operated interlocks and adjust if necessary.
4.
Inspect for loose electrical connections and damaged lead wires.
5.
Inspect all end stops and tighten bolts if required.
6.
Inspect all track switches, baffles and track device baffles or stops and straighten and adjust if damaged or
