Product Description
The flat tower cranes are used hoisting equipment in cutting-edge construction, generally composed of 4 core systems: metal structure, working mechanisms, electrical manage machine and protection safety devices.
The metal shape serves as the load-bearing framework, inclusive of the tower body, slewing platform, jib, counter jib and base frame. Without a common tower head and pull rods, it elements a compact and lifelike stress distribution.


The working mechanisms consist of hoisting, luffing, slewing and hydraulic mountain climbing systems. The hoisting mechanism controls the lifting and decreasing of loads; the luffing mechanism adjusts working radius via trolley movement; the slewing mechanism realizes 360-degree rotation; the hydraulic hiking machine permits computerized peak increment.
The electrical manipulate device adopts variable-frequency drive, presenting secure strength and unique operation. Safety units encompass load second limiter, top limiter, radius limiter and weight limiter, efficiently making sure operational safety.
With easy structure, handy set up and excessive spatial adaptability, it is in particular appropriate for intensive development websites and high-rise constructing projects.
