The most common used hoisting mechanism for tower crane

JLF series hoisting mechanism

LFV series hoisting mechanisms

JLF series mechanism and LFV series mechanism are two types of the most common used hoisting mechanism for tower crane recently. The mechanisms adopt AC asynchronous tower crane hoist 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.
