1. Metal structure
The working mechanism of tower crane consists of lifting mechanism, luffing (trolley traction) mechanism, slewing mechanism and running mechanism. In addition,L48A1 Mast Section are hydraulic jacking mechanism for the sauce making hip ten type tower crane and crane traveling mechanism for the walking tower crane.
2. Electrical system
The electrical system of tower crane is composed of power equipment of Dianqing,
L48A1 Mast Section specification and model cable and drum of tower crane, electrical switch box, electrical control device, protection device, low-voltage electrical equipment, auxiliary electrical equipment, etc.
3. Working organization
The metal structure part of tower crane is composed of underframe, tower body, tower cap, slewing support, tower top, balance arm, lifting arm, cab, ladder and platform, jacking jacket and crossbeam.

The structural parts of tower crane are exposed, usually working in the environment of - 20 ℃ - 40 ℃, and bear the erosion of rain, snow and other adverse weather. Therefore,
L48A1 Mast Section in the design and selection of materials and welding, it is necessary to take into account the low-temperature brittle fracture resistance, corrosion resistance and ice expansion damage, so as to ensure its reliable impact toughness.
4. Accessories
The auxiliary device is composed of counterweight and ballast, foundation and track, hauling device, attachment device, internal climbing frame, rope arrangement and hauling device and maintenance device.
Among the above five parts, the first four parts are necessary for tower crane, and the counterweight, ballast, track, foundation, attached connecting rod, etc. in the auxiliary device are configured according to the type and use of tower crane.
5. Safety device
Safety device is one of the essential key equipment of tower crane, which is composed of lifting height limiter, travel limiter, amplitude limiter, overload limiter, stop and buffer,
L48A1 Mast Section
wire rope anti falling device, anemometer, emergency safety switch, safety protection audio signal, emergency alarm and display recording device.
