The frequency conversion electric hoist can change the power frequency when it is working, so that the speed of the motor can be controlled, and the work efficiency can be effectively improved by controlling the rotation frequency of the motor during work.The frequency conversion electric hoist is p

The control circuit of electric chain hoist is composed of circuit breaker, contactor, transformer, terminal block, control handle button, thermal relay, wire, slide wire and other electrical components. The following protection measures must be taken in the control circuit: 1. Undervoltage protec

Electric chain hoist, also known as electric chain hoist, is a relatively common type of lifting hoist, which has several types such as fixed type, running type, low headroom type, and two-speed. Generally speaking, the main components of electric chain hoists are divided into several categories. 1.

The reliability of the brake of the electric chain hoist is directly related to the safety of people and equipment, so the requirements for its reliability are particularly high. However, there are many failures of hydraulic push rod brakes currently in use, and the main failure phenomena are:

Electric chain hoist is a combination of motor, chain, hook, etc. We all know that the core of the electric hoist is the motor. If the motor of the electric hoist is in operation, the temperature is often too high or cannot be used normally. , In this case, you should check according to the followin

After the electric chain hoist is used, it needs to be cleaned up. This work is directly related to its later storage and corrosion resistance. So how should this work be carried out? Step 1: If there are rust spots on the surface of the electric hoist, a hard metal material needs to be used to remo

As a manufacturer of electric chain hoists, we have a deeper understanding of electric hoists than most people would understand. Nowadays, electric chain hoists are everywhere in the market, and as a customer, we want to choose a high-quality electric hoist. High-quality products are even more diffi

As a common light and small lifting equipment, electric chain hoist will produce varying degrees of wear after a period of use. We should focus on the use of wear-resistant work, rather than remedy after wear. So what should we do to prevent the electric chain hoist from wearing? 1. Check whether th

Electric chain hoists are divided into many types, fixed type and operating type, conventional height and ultra-low headroom. Ultra-low headroom means that the height of the chain is much higher than that of the conventional type. The effective lifting height is relatively high. How to deal with the

A single-track electric chain hoist is not for permanent use. It has a certain technical content. How to disassemble, how to replace, every step must be very careful, and in strict accordance with the regulations and plans. 1: In the process of disassembly and assembly, the division of labor and col
