Condition of the Remote Controlled Crane
It is recommended that a written report be sent to your supervisor whenever you detect any condition that makes
the crane unsafe. Many plants supply printed forms for this purpose. The PRC crane operator shall fill out these
forms and turn them in at the end of each shift. Certain faults which the PRC crane operator may detect will be so
critical that the crane must be shut down at once and not operated until the fault is corrected. Typical check list
items may include some or all of the following:
• Condition of hoisting cable, drum and hook blocks (broken strands, clipped sheave wheels, etc.)
• Condition of brakes (hoist, trolley and bridge)
• Oil or brake fluid leaks on the runway area
• Alignment of bridge (screeching or squealing wheels indicate that bridge is out of line)
• Condition of bridge structure (broken welds, cracks and distortion)
• Broken, cracked or chipped rails on bridge or runway
• Condition and security of trolley and bridge rail end-stops (missing or damaged from impact)
• Condition of all limit switches
• Conditions of controls (electrical or mechanical defects that may lead to faulty operation)
• Condition of electric motors (carbon dust around inspection covers indicates worn brushes)
• Condition of gears (grinding or squealing may mean a lack of lubrication or foreign materials in gear
teeth)
• Frequent overload relay tripping of power circuits
• Mechanical parts loosened by vibration (loose rivets, covers, etc.)
• Wheel condition (flange wear, cracks, holes or visible signs of bearing damage)
• Bumpy riding (worn wheels)
• Worn collector shoes or bars
• Burned out, broken or inoperable warning or signal lights
• Unintended stopping or starting of any crane motion, warning device, light or auxiliary function
• Condition of walkways and ladders (missing or loose handrails, ladder rungs, etc.)
Portable Remote Controlled Crane operators shall not attempt to make any repairs by themselves.
The fault condition(s) shall be reported to a supervisor to enable repairs to be carried out by suitably
qualified personnel.
