It is a kind of new tower crane hoisting mechanism independently developed and manufactured on the basis of absorbing international and domestic advanced technologies. The mechanism is in L-shaped layout and employs the winding drum of major diameter and Lebus grooves and double-beam chassis with good rope arrangement and overall rigidity. It adopts Flender reducer which has superior performance. The mechanism adopts ac asynchronous motor and frequency control system with features of high efficiency, wide range of speed regulation large rope capacity stepless speed regulation, high-voltage dynamic performance, etc, it is applicable to building construction, precise hoisting, large rated hoisting weight and other construction sites.
