How is the crane on the construction site built
Principle is very simple, no matter how high the installation method is the same. 1. The installed base, this is very simple, base with a mobile crane hoisting in place, and then bind with bolt and foundation; Please note that this standard section is larger than the standard section so that the standard section is contained in its stomach. Also note: the climbing section is equipped with a hydraulic cylinder, which is used to lift the climbing festival to the top. When the climbing section is installed, the lifting arm is hoisted to the top of the climbing section. After the lifting arm is installed, the climb of the elevator is lifted up by the hydraulic cylinder, leaving the middle of the climbing section empty. Then, use the tower crane to lift a section of the standard section and move it to the platform outside your own climbing festival. When the standard festival is delivered to the belly of the climbing festival, the workers will tie the latest standard section to the following standard. When the bolts are joined, the hydraulic cylinder is activated and the climbing section (along with the lifting arm) is lifted upward, allowing the belly of the climbing festival to be empty again. Then, repeat the above steps for another standard section, which is up to the top of the section until the desired height is satisfied. When disassembling, reverse the steps above. "Tower crane" "tower crane"
When working in the basement, it will be installed, at this time, it will be a general mobile crane, a piece of combination. Inside the tower, there is a hydraulic jack, which is used as a climb. When the building is covered by a layer, the height has to reach the tower, and the climb is done. Fixed tower crane tower crane engineer will screw loosening, jack, will cranes rise about one meter, then pillar fixed on the structure of the building, and then narrowed jack and will be at the bottom of the fixed on the building structure, and loosen the upper screw, hold up a jack, rose again one meter, so repeatedly, backwards, a stretched to the desired height, then pillar is fixed.
To dismantle the tower crane, when building was completed in tower crane to a small crane onto the roof, then, is the contraction of jack will tower crane fell to the roof, and then decomposed into several segments, with a small crane, then small crane break down into smaller components, take the elevator down. When the tower is removed, the ground will be filled with the structure of the tower crane. There is another way is to own a jack will pillar elongation, reoccupy lets own boom lift a scape in, puckering up jack again, and so the scape is getting longer.
