With the rapid development of the economy, many buildings rise flat on the ground. In high-rise buildings, you will see that the crane used to build the building is always higher than the building. So how is the crane built? Huanghe technicians from Xinxiang Crane Rental Co., Ltd. will introduce the method of building the crane in detail below.
How to build a crane:
It will be installed during the construction of the basement. At this time, it is hoisted by a general mobile crane and assembled one by one. Inside the tower, an oil pressure jack is installed for climbing up later. When the building is covered one floor at a time, when the height is about to touch the tower crane, climbing work is required. At this time, the tower crane engineer will loosen the screws that fix the tower crane, operate the jack, raise the tower crane about one meter, then fix the tower pillar to the structure of the building, then retract the jack and fix the bottom to the building structure Then, loosen the upper screw, support the jack, and then raise it by one meter. In this way, repeat the operation, extend and retract to the required height, and then secure the tower column.
When the tower crane is to be dismantled when the building is completed, a small crane is first used to lift the roof to the roof. Then, the tower crane is also lowered to the roof with the contraction of the jack, and then broken down into several sections. The crane breaks down into smaller components and takes the elevator down.
After the tower crane is dismantled, the original structure of the tower crane must be replenished.
There is another way to extend the tower column with its own jack, and then use its own boom to lift a section of the column into it, and then retract the jack. In this way, the column becomes longer.
The above is the connection of " How is the crane built? " Through the above, we know that there is a jacking hydraulic system at the lower part of the crane. With the help of the auxiliary bracket, it can be installed and lifted in the lower section.
