A hydropower station is a core energy facility that converts water energy into electrical energy. It creates a water level difference through water blocking structures, drives the turbine to rotate, and then converts mechanical energy into electrical energy through a generator. Its stable operation relies on regular maintenance and repair. Among numerous maintenance tools, chain hoists have become essential equipment due to their strong adaptability and are widely used in the maintenance of the three core equipment.

In the maintenance of water turbines, chain hoists can be regarded as the "main equipment". Wheel and blades that are subject to long-term water flow impact are prone to wear and cracks. When disassembling, the connecting parts should be loosened first, and then the lifting point of the wheel should be fixed with a chain hoist hook to smoothly detach from the installation position. When replacing blades, its lightweight structure can accurately lift components in narrow spaces such as snail shells, avoiding collision damage.

The maintenance of generators also relies on a chain hoist. The disassembly and assembly of heavy components such as stator windings and rotors rely on their load-bearing capacity to complete lifting, and the fine-tuning function can also ensure accurate installation and positioning of the components. In addition, the maintenance of components such as the relay and bearing seat of the speed control system can be met by a 5-ton chain hoist, which can cover any position of the machine pit when used in conjunction with the lifting beam.
