Electric wire rope hoist in the daily routine maintenance inspection, monthly inspection, inspection, and who do not meet the requirements should immediately repair wire rope hoist, adjust or replace parts. Maintenance should do the following requirements: a wire rope hoist, repair and replacement of parts should be original material, the same performance; 2, when welded structures need repair, the use of materials, welding and weld quality should comply with the quality of the original structure standard; 3, electric hoist in working condition, will not carry out maintenance and repair work. Although China's domestic wire rope hoist wire rope hoist technology has been very good, but compared with foreign technology, we are still some gaps still seems very inadequate compared with some foreign technology, which is mainly manifested in the working-level structure design and matching motor three aspects: 1, the working level: CDl type electric hoist division level does not work and does not meet the actual use conditions supply wire rope hoist, causing unreasonable use in most cases. Divided by the level of new work rules cd1 wire rope hoist, working-level CDl type electric hoist for M3, while working-level range of foreign wire rope hoist adaptable for M3-M6. 2, structural design: structural design CDl wire rope hoist although more TV-type wire rope hoist has been greatly improved, but its appearance is poor, the circular structure is not easy to install, transport and shape limitations of a serious impediment to the base type changes. And foreign wire rope hoist, designed for multi-square structure, both beautiful and easy to install, transport, but also to be well adapted to the modular design, easy to mix and transform the base type, greatly broadened the scope of use of wire rope hoist. 3, matching motor: CDl type electric hoist supporting the conical rotor motor, single-speed for 4-pole, double-speed of 1/10 of picture-machine, and foreign wire rope hoist motor with 2-pole motor, two-speed dual-winding and change pole, so simple structure, small size, light weight, help to reduce manufacturing costs. In addition, CDl type electric hoist supporting the motor compared with foreign gourd insulation levels and degree of protection in terms of noise and the gap is still large. cd1 wire rope hoist | Liaoning wire rope hoist | Qingyuan Xinyu Xinyu lifting by Crane Co. provided.
