DT20 luffing crane

DT20 luffing tower crane is one of our new models of frequency control of motor speed of tower crane. Its hoisting mechanism, slewing mechanism and luffing mechanism adopt frequency control of motor speed, stable and reliable working, high efficiency and its security devices are complete that can guarantee work safe and efficient. Its maximum moment is 12 T.M, and arm length is 12 M, with a total of 4 sections. This tower crane is designed for small high-rise building construction, layout reasonable, beautiful appearance, small requirement for installation and rotary space, more convenient for small high-rise building construction requirements.
