Exploring Manufacturers of Electric Wire Rope Hoists and Wire Rope Hoists

The electric hoist is generally installed on the crane. It is a kind of special lifting equipment that improves work efficiency and working conditions. The composition of electric hoist is mainly divided into motors, electrical appliances, reducers, control boxes, wire ropes, cone motors, buttons to change. So there are several types of electric hoists? How to choose electric hoists from Electric Wire Rope Hoist Manufacturers? Read all below.

What is an electric hoist?

Electric hoist is a kind of special lifting equipment, called an electric hoist. It is installed on suspended I-beams, curved rails, cantilever lifting guide rails and fixed lifting points. It mainly carries out heavy lifting, loading and unloading, equipment maintenance and cargo lifting, etc. The work happens to be a crucial mechanical equipment for infrastructure developments like highway, construction, metallurgy and mining.

Wire rope hoist

In general, a wire rope hoist can lift much heavier loads than a chain hoist more accurately. Wire rope is made up of many strands of individual metal wires twisted together to form a strong cable, making it exceptionally strong and durable. The downside is that wire rope hoist systems can be more complex than a chain hoist, resulting in slightly higher maintenance and repair costs.

According to Wire Rope Hoists Manufacturers, in different working conditions, you can choose the appropriate electric hoist. This article briefly introduces the differences between wire rope hoists and electric chain hoists for reference.

Size:

When comparing hoists of the same tonnage, electric chain hoists are generally smaller than wire rope hoists. This is because their structures are different.

Electric chain hoists are driven by chains, and the chain bin is separated from the hoist, which solves the problem of the cable hoist drum being too large. Therefore, electric chain hoists are generally smaller than wire rope hoists. As the lifting height increases, the size difference becomes greater, as the wire rope is wrapped around the drum, which has a greater impact on the overall size.

Lifting height:

For cable hoists, wrapping the cable around the drum causes elastic deformation. The side of the drum is too tight, while the corresponding surface is tight. The smaller the diameter of the drum, the greater the deformation of the wire rope and the greater the pressure and tension on the corresponding surface. To ensure that these forces do not exceed the carrying capacity of the wire rope, the diameter of the wire rope hoist drum should be larger, so that the distortion of the wire rope is not extreme.

Design specifications require that the drum diameter of electric hoists be at least 20 times larger than the diameter of the wire rope. Alternatively, the links in a Venus Engineers electric chain hoist happens to be connected by hinges and the key force it bears is tension. Electric chain hoists have sprockets with 5 or 6 grooves generally to decrease the compressive conflict between the links and the contact surface between the sprocket and the links and sometimes 4 grooves for higher loads and lifting speeds. For these reasons, the pulley on the drum and hook of the Electric Wire Rope Hoist is much larger than the sprocket on the same size electric chain hoist. Therefore, the hook spacing of the electric chain hoist is smaller than that of the same specification wire rope hoist.

Last words

In other words, on a track of the same height, a Venus Engineers electric chain hoist can achieve a higher lifting height than a wire rope hoist.
