Crane Equipment Inspection
Introduction
In recent years, as countries increase their investment in infrastructure construction, China's exports of excavators, cranes and other engineering equipment have also increased year by year. Overseas buyers attach great importance to the quality of mechanical equipment, so the demand for inspection of engineering equipment has also increased significantly.

Key points to pay attention to in crane equipment inspection:
1. Foundation and track inspection: Check whether the gantry crane track foundation has settlement, fracture and cracking; Check the contact between the track and the track foundation to ensure that there is no hanging phenomenon; Check whether the track joints meet the requirements, generally 1-2mm, 4-6mm in cold areas; Check whether the longitudinal slope of the track meets the design requirements, generally required to be 1‰, and not more than 10mm throughout the whole process; Check whether the track gauge is over-deviation, requiring the deviation of the trolley track gauge to not exceed ±15mm.
2. Inspection of the steel structure: Check the tightness of the connection bolts of the gantry crane leg flange; Check the connection plane combination of the leg flange; Check whether the pin of the leg connection tie rod is normal, Check the tightness of the connection bolts between the lower cross beam and the leg and the connection bolts between the lower cross beams; Check the connection of the main beam connection, including the tightness of the pin or connection bolts, the deformation of the connection joint, and the condition of the welding welds at the connection joint.
3. Inspection of the trolley running part: Check the wear and cracking of the running wheels, whether there is severe deformation, whether there is severe wear or no wheel rim, whether the speed reducer lubricating oil is sufficient and the quality of the lubricating oil; check whether the reducer housing is cracked and whether there is oil leakage; check the brake clearance of the brake, the wear of the brake pads, and the wear of the brake wheel.
4. Inspection of the main lifting mechanism: Check the wear and cracking of the running wheels, whether there is severe deformation, and check the operation of the trolley running mechanism.
5. Inspection of other important components: including the performance and status of key components such as brakes, reducers, motors, couplings, etc.
Through detailed inspections in the above aspects, the safety and reliability of the crane equipment can be ensured to avoid accidents and failures during use.
Weproving Inspection not only provides 100% new mechanical engineering equipment inspection, but also provides inspection for second-hand excavators, cranes and other equipment needs.
