No matter how large the mechanical equipment is, it is composed of various components. Therefore, when purchasing lifting machinery, users must not ignore the quality inspection of each component to purchase reliable equipment. SINOKOCRANES summarizes the key components that require focused inspection.
For brake safety devices, it is necessary to check the working condition of components including brakes, pull rods, springs, pin shafts, mandrels, brake wheels and brake friction plates. In addition, inspect the hydraulic system, braking performance and braking clearance to ensure all indicators are in good condition. Qualified performance of the above parts means the components meet quality standards.
When inspecting sling components for defects, check accessories such as hooks, hook anti-drop devices, pin shafts, steel wire ropes, pressure plates, rope clamps and wedge blocks, and verify whether they match the pulleys and drums.
For reducers and couplings, focus on the performance of the reducer and the safety and reliability of all coupling components, including pin holes, pin shafts, buffer rubber rings and reducer fixing bolts. The components are qualified if all relevant requirements are met.
In addition, SINOKOCRANES reminds that key inspections shall also cover the oil level, oil quality, lubrication condition and sealing condition of the reducer, as well as the concentric connection state of the coupling.
Furthermore, for drums, pulleys and wheels, inspect the quality and performance of key parts including drum body, drum flange, rope groove, drum wall, rope guide, pulley, anti-rope-off device, pulley groove, pulley flange, wheel tread and wheel shaft to confirm no quality defects and compliance with performance requirements.
The above is a brief introduction to the quality inspection of various crane components compiled by SINOKOCRANES. Please follow our official website for more relevant information.
