The stable operation of thermal power plants relies on regular equipment maintenance and repair, and among the numerous repair tools, the chain hoist has become a key equipment for improving repair efficiency due to its unique advantages. It can not only achieve vertical lifting of heavy objects, but also be used in conjunction with other tools to meet complex maintenance needs.

In the scenario of generator maintenance, the disassembly and assembly of the generator stator and rotor is an important step. The stator has a large volume and heavy weight, and traditional lifting methods are difficult to accurately control. The hand pulled hoist, with its flexible installation method, can adjust its fixed position according to the on-site space, and achieve vertical lifting and translation of the stator through manual operation, avoiding damage to the precision components inside the generator due to unstable lifting. At the same time, during the lifting process of the chain hoist, its tightening and fixing effect can ensure that the stator remains stable during disassembly and assembly, creating a safe working environment for the staff.

In addition, the combination of chain hoists with steel wire ropes and shackles further expands their application range. During the maintenance of the heat exchanger, it is necessary to remove the heavy heat exchange tube core from the shell. The staff first securely connect the chain block to the core using a release buckle, and then use the traction effect of the steel wire rope, combined with the vertical lifting function of the chain block, to smoothly pull out the core. This combination not only enhances the safety and stability of lifting, but also significantly shortens the maintenance time. The disassembly and assembly of the tube core, which originally required several hours, can be completed in a shorter time through the synergistic effect of the assistant hoist and other tools, effectively accelerating the equipment maintenance speed of the thermal power plant and ensuring that the unit can resume operation as soon as possible.
