[0002] The structure and characteristics of the wire rope electric hoist: It adopts a mechatronic design. By replacing different molds, it can press wire ropes of different specifications. It is easy and safe to operate; it is convenient to inspect, install and maintain the motor.

[0003] The lifting drive device of the wire rope electric hoist usually consists of a three-in-one drive device consisting of a brake + motor + parallel shaft reducer. Since the electric hoist is a heavy-duty equipment and its reducer is a heavy-duty reducer, the lubricant needs to use VGA680 with a higher viscosity. Due to the high viscosity of the lubricant and the large flow resistance, and the high speed of the motor, the first stage (high-speed stage) of the reducer is less efficient during operation, which in turn reduces the efficiency of the entire three-in-one drive device.
