Tow wire electric hoist

Electrical Wire Rope Hoist Specifications

Overhead lifting devices have different types and shapes and functional mechanisms, but almost all of them have a very important functional member and part in common. The lift section is present in all cranes. Industrial elevators are produced and supplied in two types, the chain group and the wire rope group, their actuators are manual or electric and sometimes hydraulic, each of which has its own characteristics and uses, which are related to wire rope elevators and their use in this section. let's pay

Towing rope hoists have many varieties, each of which has a specific use, electric towing hoists are divided into two types, single-speed and two-speed, and they work with three-phase or single-phase electricity and have There are also different movement speeds, in general, the towing lifts are four-way or double-way, which means that lifts with only hook movement up and down are called double-way.

And in the case where up and down movement and lateral movement are needed on both sides, four-way or four-way elevators should be used, these types of elevators can be used in different industries, and these types of elevators are used for All kinds of industrial cranes are used.

In these lifts, steel ropes called tow wire are wrapped around a metal cylinder that must be machined exactly according to the diameter of the tow wire and have grooves, and that metal cylinder (known as wire guide), wire They guide the towing and finally lift the load with a hook that actually consists of a pulley and a hook at the end.

The law of compound pulleys allows the lifting spectrum to move even very heavy loads, although according to the same law of compound pulleys, it should be noted that with the addition of pulleys, the lifting speed decreases and increases in proportion to the capacity. This work (knowing the mechanism of pulleys and increasing and decreasing capacity and speed) is very specialized, and before implementation, you must pay attention to the cable hoist catalog and observe the technical points and standard requirements.
