Inspections and Training

All applicable code violations will be noted.

BRIDGE AND TROLLEY DRIVE

• Check wheel flanges and tread wear.
• Check wheel bearings for damage, lubrication.
• Check couplings, pillow blocks, shafts, gear cases and wheel gearing for wear, damage and lubrication.
• Check braking for brake wheel wear, proper adjustment, lining wear, hydraulic reservoirs, hoses, etc.

HOIST DRIVE

• Check hoist drum, bearings, sheaves, and wire ropes for wear, damage and lubrication.
• Check hoist gear case for gear wear, load brake or load clutch adjustment, coupling damage and proper lubrication.

BRIDGE

• Check bridge end truck for fatigue, damage, proper bumper.
• Check girder to end truck connection for loose and stretched bolts, cracked welds and fatigue.
• Check bridge girder camber, trolley rail alignment and wear, beam flange wear, footwalk and drive supports for damage and fatigue.
• Check hand rails, footwalk, access ladders for proper construction, fatigue and damage. 
• Check main line and cross conductor support toe arms for damage and alignment.
• A general check of runway structure rail alignment and wear, elevation problems and structural damage.

TROLLEY FRAME

• Will be checked using the same format as the bridge.

NOTE: Electrical components will be inspected in conjunction with the National Electrical Codes (N.E.C.)

BRIDGE, TROLLEY & HOIST

• Check NEMA enclosures and conduit for proper clearances, installation, and damage.
• Check wiring for proper sizing, insulation damage, outdated wires, loose or corroded terminal connections and proper markings.
• Check reversing, speed, and relay timers for contact tip wear and damage, terminal connections, and proper sequence and timer adjustment.
• Check fusing and motor overload protection for proper sizing, damage, etc.
• Check mainline and cross conductor systems for wear, damage and connections.
• Check motors for stator and windings wear and damage.
• Check control stations, master switches for damage, proper sequences, markings, contact tips, etc.
• Check limit switches for contact tip wear and arcing, proper actuating, etc.

BRIDGE & TROLLEY

• Check drive mechanism for tracking or skewing problems, binding on rails.
• Check control for proper speed sequences, reverse plugging (when applicable).
• Check braking for proper stopping distance.

HOIST

• Test mechanical, eddy current and controlled braking for proper function.
• Check holding brakes for drifting and proper adjustment.
• Check limit switch devices of proper actuating.
• Check control sequences for proper speed control.
• Check hoist wire ropes for proper seating and reeving on sheave and rope drums.
• Check upper and lower sheaves for free movement.
