L68B1 Mast Section Classification and composition of tower crane parts
The metal structure of tower crane consists of crane arm, tower body, turntable, bearing base, balance arm, bottom, spire and so on. The components of the tower crane are steel wire cross (the main force-bearing parts of the lifting) , luffing trolley (the car consists of frame structure, steel wire rope, pulley, traveling wheel, guide wheel, steel wire rope supporting wheel, steel wire rope anti-release, trolley traction tensioner and rope-breaking fuse, etc.) , pulley, slewing support, Hook and brake. There are five kinds of working mechanism: lifting mechanism, luffing mechanism, trolley traction mechanism, slewing mechanism and trolley running mechanism (walking tower crane) .
Tower Crane electrical equipment includes hydraulic pump, hydraulic cylinder, control components, tubing and pipe joints, fuel tank and hydraulic oil filter and other major components. For Safety Systems and attached anchors, limit switches (limiters, overload fuses (overload and power-off devices) , buffer stops, wire rope trip preventers, anemometers, emergency safety switches, safety protection audible signals.
And generally speaking, jack-up tower crane in the process of building construction, the installation of 2 anchorage has been able to meet the needs. Attention should be paid to the selection of attachment points on buildings: the distance between the two attachment points should be appropriate, the fixed points should be set at the corner of the t-shaped wall and the outer wall, and the attachment points should not be near the root of the columns for the frame structure and the attachment points should be arranged near the floor slab to facilitate force transmission and installation.
