Safety inspection of common Overhead Crane parts

Safety inspection of common Overhead Crane parts

(1) hooks.

Check the hook mark and anti-off device is in line with the requirements, whether the hook, stripping and other defects; hook section wear, increase the degree of opening, reverse deformation, whether excessive; hanging neck and surface fatigue Deformation, cracks and related pin, sleeve wear situation.

(2) wire rope.

Check the wire rope specifications, type and pulley reel match to meet the design requirements. Wire rope fixed end of the pressure plate, rope card, block and other wire rope fixtures meet the requirements. Wire rope wear, broken wire, kink, flattened, bending, broken, corrosion, etc. are exceeded.

(3) Brakes.

Brake discs, brake discs, brake pads, brake pads, brake pads, brake pads, brake pads, brake pads, brake pads, brake pads, brake pads, brake pads, brake pads, brake pads, ; Brake clearance adjustment, braking capacity can meet the requirements.

(4) reel.

The thickness of the reel and the number of wire rope winding can match; guide rope, row rope work is consistent with the situation; Claim;

(5) pulley.

Whether the pulley is equipped with anti-rope groove device; pulley rope groove, rim whether there is crack, broken edge, wear and other conditions, pulley rotation is flexible.

(6) reducer.

When the reducer is running with or without severe metal friction sound, vibration, shell radiation and other abnormal sound; shaft seal is tight, fixed bolts are loose and other conditions; reducer lubricating oil selection, oil level, vertical reducer lubrication Oil pump operation, open gear transmission lubrication, etc. meet the requirements.

(7) wheels.

The tread of the wheel, whether there is fatigue crack on the axle, wheel tread wheel wear is excessive. Whether the phenomenon of gnawing in the operation. What is the cause of the gnawing track?

(8) Coupling.

Coupling parts with or without defects, connecting loosening, running the impact of the phenomenon. Coupling, pin, shaft pin hole, buffer rubber ring wear is excessive. Whether the coupling is concentric with the two components being connected.
