Depending on the structure of the building, there are different ways of changing altitudes. Tower crane is basically algae because the body of the tower, the joint wants to extend or shorten the height, it can be long or remove the tower body from the top of the tower or between the tower.

Some types of cylinders are used hydraulic piston mechanism to adjust the height of the tower.

The mechanism of hydraulic piston lifting and lowering

Using a hydraulic piston mounted in a lifting cage to lift or lower the tower body burners with gear transmission, or hoist.

Extend the tower body from the top of the tower

This is considered a very dangerous way to raise the height, the process is also very time-consuming and has a great impact on the progress of the project. With this way of connecting the body of the tower, make sure to maintain the side of the frame, usually with the type of need to rotate, it is necessary to use this method.

Extend tower body by climbing the floor

Extend the tower body from the center of the tower

As the most convenient and popular way, the hoist of the tower crane can bring itself to connect the body to the center of the tower, ensuring the construction progress and safety when lifting and lowering.

Note during the lifting process

• Labor protection is required for people who perform the assembly process to avoid bad cases.
• Accurately calculate the height to lift and when lifting, it is necessary to stop all activities to avoid any problems.
• Tests must be signed and maintained regularly to ensure the quality and capacity of the plant are stable and increase the life of the tower crane.
