Now, as more and more people pour into cities and towns, the demand for housing is also increasing.

Houses entering the city are also being built everywhere.

In each construction site, the function of crane is indispensable.

Construction lifting machinery refers to all kinds of tower cranes, gantry cranes, construction hoists, material hoists, high work baskets and integral lifting scaffolding.

The reason why cranes are so important is that with the popularity of urbanization, people's requirements for houses are no longer shelter from the wind and rain, and even aesthetic requirements.

We can see that high-rise buildings in many cities need to rely on cranes to complete, not only high efficiency, but also can save manpower.

1. As a lifting equipment and machinery, the crane, as the name suggests, is to lift the items of the house, mainly the bricks when the house is built, and it is also the main lifting object.

The crane carries the installed bricks on the top to have workers to operate.

As an important part of lifting, the consignment of bricks is a very important part of the building.

2. In addition to brick transportation, cranes are often responsible for lifting iron products such as mechanical steel bars in the construction industry, transporting these things to the infrastructure of the building.

And then gradually carrying down the things needed for the above construction, thus ensuring the smooth progress of the whole project.

3. The task of the crane in the roof sealing and improvement of the whole house is processing, so that the internal materials can be laid after the completion of the whole structure of the building.

These materials can be lifted smoothly through the crane.

And then successfully complete the process of building the house.

There are many types of cranes.

1. According to the lifting nature: mobile crane, tower crane, mast crane.

2. According to the driving mode: one is centralized driving, that is, one motor is used to drive the long drive shaft to drive the active wheels on both sides, and the other is driven separately.

That is, the active wheels on both sides are driven by a motor.

Small and medium-sized bridge cranes mostly adopt the "three-in-one" driving mode of brake, reducer and motor. Ordinary bridge cranes with large lifting capacity often use universal couplings in order to facilitate installation and adjustment.

3. According to the structural form, the crane is mainly divided into light and small lifting equipment, bridge type (bridge type, gantry crane), jib type (self-propelled type, tower type, portal type, railway type, floating ship type, mast type crane) and cable type.
