Factors affecting the service life of wire rope electric hoist

The lifting organization of the wire rope electric hoist is a running motor, and its operating principle and service life are directly related to the service life of the motor. The working principle of the wire rope electric hoist is: first start the hoisting motor to lift the weight to a suitable height, then start the motor to transport the weight to the designated position, and the trolley walks on the lower edge of a single I-beam. When walking, the wheels on both sides of the trolley are driven by electric motors. Because the traveling speed is relatively small, the traveling vehicle is not equipped with braking organization. In order to prevent heavy objects from falling, electromagnetic brakes are installed on the lifting organization when the trolley is walking. The braking principle is similar to that of a friction clutch. When releasing, use an electromagnet to attract the outer disc and release the inner and outer discs.

The service life of the wire rope electric hoist is not only directly related to the installation, disassembly, protection and maintenance, but also has an important relationship with the motor. The quality of the motor directly affects the service life of the wire rope electric hoist. Doing necessary maintenance and maintenance of the motor and allowing it to rest properly can relatively increase its service life.

Look at the material: The material can generally be seen that the housing of electric hoist made of good steel and bad steel is different. Okay, the general quality is uniform, thick, thin and fragile. Look at spray paint: there is a visual gap between good paint and secondary paint. Generally speaking, the good paint is bright, and the second paint is muddy. It is easy to distinguish with the naked eye. Look at the equipment: the equipment and quality are directly related to the equipment of the general high electric hoist, and the quality will be higher. It can be analyzed based on the information of limit, braking system, motor, electrical appliance, load limit and so on. Look at the brands and manufacturers: Brands and manufacturers are different, and the quality and price are also quite different. If you buy a wire rope hoist from a well-known manufacturer, the product quality is relatively high. If there is only a stall or a small workshop, it is conceivable that the quality cannot be guaranteed.
