132HC Mast Section How to check universal parts of lifting machinery
(1) Hook
Check the mark of the hook and whether the device meets the requirements, and whether the hook has cracks, cracking and other defects; The wear and tear of the hook section, the increase of the opening degree, the torsion deformation, whether it exceeds the standard; There is no fatigue deformation, crack and wear of the pin and sleeve on the neck and surface of the hook.
(2) Steel rope
Check whether the wire rope specifications, models and pulley rolls match the design requirements. Whether the steel wire rope fixing device such as the pressure plate, rope card and the forging block meets the requirements. Is the wear, breaking, twisting, crushing, bending, breaking, corrosion, etc. of the wire rope exceeded the standard.
(3) Brake device
Brake setting, brake type meet the design requirements, brake rod, spring without fatigue deformation, cracks and other defects; Whether the pin shaft, heart shaft, brake wheel, brake friction sheet wear excessive, whether hydraulic brake oil leakage; Brake clearance adjustment, braking ability can meet the requirements.
(4) Slow down machine
Whether there is any abnormal sound such as sharp metal friction sound, vibration, shell radiation when the speed reducer is running; Whether the shaft end is well sealed, whether the fixing bolt is loose or defective; Selecting lubricating oil of reducer, oil surface height, running oil pump of vertical reducer, driving lubrication of open gear meet the requirements.
(5) Connectors
The coupling parts have no defect, loose connection and impact. Is the wear of coupling, pin, pin hole and buffer rubber ring excessive? Whether the coupling is concentric with the two connected parts.
(6) Roller
There are no fatigue cracks or breakages in the cylindrical body and edge. Whether the rope grooves and tube walls wear excessive; Can the height of the rims match the number of winding layers of the wire rope? Whether the working condition of the tether and loader meets the requirements;
