The components of tower crane are composed of steel wire rope (the main load-bearing parts to be lifted), luffing trolley (the trolley is composed of frame structure, steel wire rope, pulley, traveling wheel, guide wheel, steel wire rope supporting wheel, steel wire rope anti falling roller, trolley traction tensioner and broken rope protector), pulley, slewing bearing, hook and brake.




There are five working mechanisms of tower crane: hoisting mechanism, luffing mechanism, trolley traction mechanism, slewing mechanism and crane traveling mechanism (walking tower crane).




Tower crane electrical equipment includes hydraulic pump, hydraulic cylinder, control elements, oil pipe and pipe joint, oil tank and hydraulic oil filter and other main components.




For tower crane safety system and attachment anchorage, limit switch (limiter), overload protector (overload power-off device), buffer stop device, steel wire rope anti falling device, anemometer, emergency safety switch, safety protection audio signal. Generally speaking, in the process of building, the self elevating tower crane can meet the needs by setting two anchoring inks.




Attention shall be paid to the selection of the attachment points on the building: the distance between the two attachment and reinforcement points shall be appropriate; the fixed points shall be set at the corner of the T-shaped wall and the external wall; for the frame structure, the attachment points shall be arranged near the root of the column; the attachment points shall be arranged near the floor slab to facilitate the force transmission and installation.
