crane unsafe to operate), the crane should be shut
down immediately and the supervisor notified. The
following is a list of what should be included in the
report:
Condition of hoisting cable and hook block

Condition of brakes (hoist, trolley, and bridge).
Alignment of bridge (screeching or squealing wheels
indicate bridge is out of line).
Broken, cracked, or chipped rails on trolley or
runway.
Condition of limit switches.
Condition of electrical and mechanical control
(electrical or mechanical defects which cause faulty
operation such as un-commanded stopping or starting
of any crane motions, warning devices, lights, or
auxiliary functions).
Condition of gears (grinding or squealing may
indicate foreign materials in gear teeth or a lack of
lubrication.
Frequent relay tripping of power circuits.
Mechanical parts loosened by vibration (loose rivets,
covers, bolts, etc.).
