What are the main parameters of a tower crane?
Generally speaking, the main parameters of the tower crane are:Maximum amplitude unit MMaximum lifting height, unit MMaximum lifting torque unit KN.mMaximum lifting speed unit m/minMaximum lifting unit tRotational speed unit r/minVariable speed unit m/min or o/minWalking speed per unit m/minMotor power unit w......Please refer to the product manual.
For car luffing tower cranes, the maximum lifting height is only related to the height of the tower, and when the height of the tower is determined, the maximum height of the ceiling is a certain value.In addition to the 4 major performance parameters. And the working speed (including lifting speed, rotary speed and walking speed of car, traction speed), an important parameter gauge, wheelbase, total power, motor structure weight, balance and gross weight, etc.. These important parameters often determine the tower crane selection, such as speed of operation often determines the number of selected cranes, motor power requirements of power supply load, gauge, wheelbase of the site, and the structure weight, balance weight, weight of the foundation treatment of heavy machine requirement.Tower crane (tower crane) is called tower crane, also known as tower crane. 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. The tower crane 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..
The main parameters of tower crane are:1, rated lifting torque. Lifting torque is the most comprehensive reflection of tower crane performance because the lifting torque itself is the product of the two parameters of magnitude and weight. The lifting moment is the product of the lifting and the amplitude.2, lifting range. The lifting range is also referred to as the radius of gyration or the radius of work. It refers to the horizontal distance from the center of the tower crane to the center line of the hook. The range contains two parameters of maximum amplitude and minimum amplitude.3. Rated lifting capacity. Rated lifting capacity refers to the weight of a crane under different working conditions. In general, the lifting capacity and the maximum lifting weight are marked in the main performance parameters, and the rated weights of other states are determined by their characteristic curves.4, maximum lifting height. For boom type tower cranes, the maximum lifting height according to the boom of the elevation and the tower height is different.
