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:
