Electric hoists, everyone knows that their safety is much better compared to hand-pulled hoists. This is inseparable from its structural principle, and among these, the wire rope electric hoist has its own unique characteristics. Below, let's take a look at the structural principle of the wire rope electric hoist.

Reducer: A three-stage fixed-axis helical gear transmission mechanism is adopted. The gears and gear shafts are made of heat-treated alloy steel, while the housing and cover are made of high-quality cast iron, ensuring tight assembly and good sealing. The reducer is an independent component, making installation and removal extremely convenient.

Control Box: It adopts a device that can cut off the main circuit in emergencies and comes with upper and lower travel protection and fire-limiting limiters, ensuring the safe operation of the electric hoist. The electrical components have a long lifespan and are reliable in use.

Wire Rope: GB1102-74 (6*37+1) X-type lifting wire rope is used, guaranteeing durability over time.

Conical Motor: The lifting motor uses a conical rotor braking asynchronous motor with a larger starting torque, eliminating the need for an external brake. The motor load duration rate is 25%, and it uses B or F class insulation. The motor protection rating is IP44/IP54.

Button Switch: Hand-operated, lightweight, and convenient, it comes in two types: rope-controlled and wireless remote control.

The structural principle of the wire rope electric hoist determines its advantages and has received positive feedback in the market. A deeper understanding of the wire rope electric hoist can help you better maintain and care for it, allowing the wire rope electric hoist to play a greater role in work. Improving its efficiency also increases your income.

Due to its unique characteristics, the wire rope is one of the most frequently used components in electric hoists. Compared to rigid components, wire ropes have high strength, low self-weight, good flexibility, and resistance to impact, especially standing out in terms of safety reliability.

The safety technology of wire ropes involves multiple issues such as the type, manufacturing method, structural performance, stress condition of the wire rope, as well as maintenance, inspection, and scrapping, which is a relatively specialized technical field. Every safety manager and technician should be knowledgeable about wire ropes.

Under normal conditions, the wire rope used in the wire rope electric hoist generally will not suddenly break. Even if it does get damaged, there are usually precursors, typically starting from individual or local broken wires and gradually developing to the entire rope over a period of time, unless the load exceeds its ultimate breaking force, causing sudden failure of the entire rope. This provides a possibility; as long as daily safety management and usage of the wire rope in the electric hoist are strengthened, accidents caused by the wire rope can be avoided.

However, the stress conditions of the wire rope in the electric hoist vary greatly, and the working environment is complex. Its damage is not only due to mechanical injury but also related to improper structural selection, improper maintenance and inspection, and the failure of the wire rope not being timely scrapped and updated.
