The hoist is a special attachment that is used as a winch, that is, to lift and hold any weight during loading and unloading. This unit has its own characteristics and advantages.
Features and use of hoists
I must say that the presented device is installed only in a horizontal position. It can be used in closed pavilions and in open areas. Most often, such equipment can be found in production shops, warehouses and railways, where wagons are unloaded or loaded. In everyday life, telpher is used relatively rarely.
The presented equipment is also used for work in such rooms where a person cannot perform any activity, for example, in laboratories where the use of chemical or other hazardous substances that can negatively affect health is provided. The telpher is a unit that is simply indispensable in workshops with very high air temperatures.
However, you can not always use this equipment:
- you can’t move people with it;
- it is better not to use the hoist for the transport of hazardous liquids, as well as hot metal;
- do not use such an apparatus in those places where there is an increased risk of an explosion.
The advantages of the presented equipment
The telfer is a necessary equipment, which, in addition, has a large number of advantages:
- durability (the device is made of high-quality materials that are not susceptible to corrosion or rust for a long time);
- small size and weight;
- the possibility of mounting on large bridge cranes;
- simplicity and ease of use; most models have automatic control;
- control over the lifting speed and movement of the load;
- good security system;
- low cost of operation;
- variety of models;
- possibility of use in difficult conditions.
Types of equipment
The telpher is an effective equipment that can be divided into several types according to the type of drive:
- Manual. This is the simplest equipment option that does not require any energy costs. The only force that sets it in motion is human. That is, for the operation of such an apparatus several workers are needed.
- The hoist is electric. These units are the most common and effective. Their work requires electricity. They can do the rest without direct human intervention, using automation.
- Pneumatic The basis of the operation of such equipment is compressed air. Therefore, it can be used in particularly difficult conditions (in buildings with increased explosion hazard). Naturally, the presented unit should be equipped with a compressor unit that will pump air.
Device design features
Since the electric hoist is most often used in work, it is precisely its design that should be considered. Although all the models of the presented devices do not have any special differences.
So, the presented unit consists of a gearbox, an electric motor, a drum (asterisk), a hook and a brake. To control such a device, a special button remote control is used. If the traction element is a rope, then the hoist will be equipped with a drum. If it is equipped with a chain, then it is wound on an "asterisk".
Features of the choice of equipment
If you need a hoist, then you need to choose it carefully and correctly. To do this, several parameters should be considered. The size of the hoist is not practical, since in most cases they are attached to an overhead crane. You should determine the type of drive device. An electric apparatus is most often used, but in conditions of high concentration of explosive gases in a room it is better to use a pneumatic model. If you need to lift a small load, you can purchase a manual installation.
In addition, you need to decide whether you need a stationary or mobile device. Large workshops most often use a hoist crane, which can stand still or ride on rails. Naturally, during the selection, it is necessary to take into account the carrying capacity of the device and its performance.
Pay attention to additional functions, if necessary. Naturally, such models are much more expensive. Therefore, if you do not need special features, then you can save.
Naturally, such equipment should be bought only in certified stores where you can get a guarantee for your purchase. If you have already chosen a suitable model, then carefully examine it for marriage or any damage.
Now you know what a hoist is, how it is used and how to choose it.
