How do tower cranes rise?
The weight and concrete foundation shall be made in advance and marked, and the ground ground endurance shall be no less than 20T per square meter. The chassis and standard sections are then assembled on this basis. The standard section of tower crane is the main part of the main part of tower crane. It is also the main role of heightening the height of tower crane". In the construction process, tower crane accompanied by the rise of buildings, naturally need to heighten. When the tower is hoisted, the upper frame is raised upwards with the jack up, so that there is a space between the tower body and the frame, and the standard section of the tower body is installed in the space. In this way, the purpose of the tower crane is realized.
Tower crane, or tower crane, commonly known as tower crane, originated in Europe in the early twentieth Century. It has been used for more than one hundred years, and plays an important role in transportation, logistics, construction and other fields. Since tower cranes look like a tower far away, the way they lift up has become a topic of interest. In fact, according to the functions of the crane can be divided into: foundation, tower, lifting, rotating, lifting, balancing arm, lifting arm, lifting trolley, tower, cab, variable part in building tower crane should first install base part. That is to determine the tower crane erection position, determine the principle to maximize the tower crane construction capacity, convenient tower crane entrance and exit and installation, disassembly. Then choose the right foundation type.
A tower crane raises weights by clicking on the reverse;Tower crane (tower crane) is called tower crane, also known as tower crane, originated in Western europe. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..
