Electric hoist is a kind of lifting equipment. In the process of long-term use, various problems will inevitably occur in various parts. Let me explain to you some easily damaged parts of the electric hoist. We hope that more attention should be paid to the maintenance of these parts in the future use.

  • Rope guide. The rope guide is used to prevent the rope entangled on the drum, and the steel rope will create friction with it. After a long time, the rope guide will be more easily damaged.
  • Upper and lower limit device. The limiter is a device that cuts off the power when the hook is raised to a certain position. It can prevent certain accidents from happening, but in the process of long-term use, collisions inevitably occur. The limiter is also one of the easily damaged parts.
  • Reducer. During the operation of the electric hoist, when it suddenly encounters an emergency and needs to decelerate to a stop, various actions of the equipment may damage the gearbox.
  • Brake. When the brake system is used for a long time, it may slip.
  • Gear. During the operation of the electric hoist, the gears may wear out after a long period of frictional engagement.
  • Wire rope or chain. As one of the main load-bearing parts, the wire rope or chain will inevitably produce friction during the lifting of heavy objects. Therefore, after a long time of use, the wire rope or lifting chain will suffer from scratches, cracks and deformation due to wear.
  • Hook. The hook is the part of the electric hoist to link the lifting object. Behaviors such as overweight or sudden acceleration will increase the opening of the hook. If it does so for a long time, it will reach the scrap standard. As long as there is no timely inspection and maintenance, there is a danger of heavy objects falling.
  • Motor. It is the heart of the electric hoist. It drives the operation of the whole hoist through rotation. Once the voltage is unstable or the weight of the hoisted object exceeds the rated lifting capacity of the electric hoist, it will cause loss and affect the service life of the electric hoist.

The above points are the components that are prone to failure in the use of electric hoist. The damage of each component will have a certain impact on the electric hoist. Therefore, in order to ensure the service life of the electric hoist and the safety of the operator, everyone should pay attention to the inspection before use, the operation during use, and the storage after use when using the electric hoist. All must comply with the rules for the use and maintenance of the electric hoist.
