Main accessories of electric chain hoist
There are many accessories that make up the electric chain hoist, including motors, reducers, running cranes, chains, hooks, covers, etc. The main parts of electric chain hoist, motor, reducer, and running trolley are introduced below.
Motor: The motor is the core of the electric hoist and the source of power for the electric hoist. The improvement of the level of motor manufacturing is the basis for the improvement of the performance of the electric hoist. With the advancement of technology, the motor is also developing for high power and large tonnage, while taking into account energy conservation and environmental protection. characteristic. The new generation of motors widely use cylindrical planar disc brakes, which can achieve 2-12 pole-changing speed regulation, and the shell is made of die-cast aluminum material, which has good heat dissipation performance and small specific gravity. The success of pole-changing speed regulation and frequency conversion speed regulation technology is greatly The overall performance of the electric hoist is improved, and the application scope of the electric hoist is further expanded.
Reducer: The reducer of the electric hoist mainly relies on gears, and the gear materials used in the new generation of products are mostly processed by carburizing, quenching, gear grinding and other processes, with good hardness, strong heat resistance, wear resistance, impact resistance, and corrosion resistance , Is one of the basic ways to improve the carrying capacity of the electric hoist and prolong the service life of the electric hoist. The housing of the reducer is made of die-cast aluminum or precision cast steel, which can realize seamless connection with the shell.
Running trolley: the new generation of electric hoist running trolley adopts side layout, mainly to increase the effective lifting height, and realize cost savings. Based on the side layout, the combined anti-roller can balance the weight and load of the lifting mechanism. The material of the running trolley is generally made of alloy steel or ball milled cast iron, and the traveling mechanism is basically horizontal wheel-oriented. This is because the film of the running trolley wheel will be filmed with the track during most of the travel, and the wear at the edge is often large, and the horizontal wheel is used. It can reduce driving resistance, thereby reducing wear and extending track life.
