The main components of tower cranes

Tower cranes can be divided into three parts: metal structural parts, body parts, control parts. The three most tower  bridge gantry crane  production costs in proportion roughly as follows: 60%, 30%, 10%.
3.1 metal structure
Crane crane metal structure is the skeleton. Its role is to bear the weight of the crane and the operation of various external loads by crane, balance arm, tower caps, turret, tower and chassis (walking tower crane also includes frame rails, door frame , outrigger beams, etc.) and other components. Cranes working bodies of the parts are installed or supported on the metallic structure, change the part of the selection and structure is reasonable and is closely related to the safety of tower cranes. The fraction of the cost performance parameters of the crane is not only, but also on the various components of the structure and is closely related to the material of choice.
3.1.1 The main structure
The main tower crane tower crane structure is to determine the cost, one of the main factors, the same argument used tower  steel crane  over different structural forms, in the same load under the action of the metal structure of the tower crane forces also are exposed different, the size of the natural materials used are different, their production costs will also be very different, but different structural forms have their own strengths, suitable for different project needs, they are widely used in the world, has a strong vitality . Only by understanding their characteristics, the force and the cost situation, in order to properly purchase and use of tower cranes.
Affect the cost of the larger main tower  overhead gantry crane  structure: tower crane superstructure, tower and chassis systems. However, due to time constraints this only describes the tower crane upper structure.
