About Electric Hoists

Things you need to know about electric hoist

An electric hoist is an essential piece of equipment for lifting work. It can raise and lower objects vertically by a mechanical advantage, which is a motor. In general, electric hoists are divided into two types: electric wire rope hoist and electric chain hoist.

How does an electric hoist work?

Most electric hoists are designed to lift small loads, between one hundred and two hundred kilograms. Therefore, they are lifting machines with a wide variety of applications in the construction world and allow the movement of small devices within a work or industry. There are also plenty of electric hoists which are capable of loading more weight. The average load weight varies between 250 kg and 5 tons. The most common is the 2 ton electric hoist.

Most electric hoists are designed to lift small loads, between one hundred and two hundred kilograms. The equipment consists of the hoist, operated with a command and equipped with an electric motor, a pulley, and a support for the assembly. The latter can be of two types: a rotating arm with a tubular structure on a pole and a winch with a sliding rail. Therefore, they are lifting machines with a wide variety of applications in the construction world and allow, for example, the movement of small machinery within the work, the movement of bags of cement and aggregates to make concrete in a small mi Hoist installation. Depending on the type of support structure, hoists are divided into different categories. In the case of hoists with a tubular structure rotating arm on a pole, the horizontal movement is carried out using the same oscillating arm that rotates with the axis coinciding with the vertical bar. The installation procedure is simple. It is enough to mount the vertical tube that supports the hoist structure, which serves as the axis of rotation. Xer, the movement of bricks for the construction of enclosures, and so on. Said vertical tube is vertically braced utilizing two tubes of smaller diameter, which are on the ground joined to two other horizontal lines. It is also connected to the base of the vertical post and weighted in its final part.

In the upper part of the vertical tube, there are two support points, in which the horizontal beam that will support the hoist will be inserted, as well as another vertical bracing, which limits the arrows of the hoist when it is activated to lift loads.

What are pulleys and hoists?

Both are a mechanism that allows the passage of a rope through the throat of a wheel to reduce the magnitude of the force necessary to move weights and obtain a mechanical advantage.

What is a chain hoist?

The chain hoist is a mechanical device that aids in the lifting of large, heavy loads. This device makes the force that must be applied to lift something much less than the weight that must be moved. The chain hoist consists of one or more pulleys and is carried utilizing a chain gear.
