This machine is a tower crane with horizontal arm, upward rotation and self-climbing. With a nominal load moment, the machine is largely used for the lifting operations in steel structure construction, big industrial plant building, tall building or super-tall building civil architecture and other projects. The machine stands at a net weight of *8.*5 meters and reaches a max. lifting height of **2 meters and even extends up to **0 meters in special case. The max. operation range can be *5, *0, *5 and *0 meters according to the needs and max. lifting weight is *0 tons. All the working mechanisms of this machine apply various advanced technologies, the control system applies PLC and the lifting mechanism applies double-winding motor that operates stably and reaches the position accurately. The speed can reach **0m/minute. While lifting, the speed can be varied stable from low level to high level. Its advanced property and working reliability are at leading domestic level. The driver's room provides a broad view, convenient operation and comfortable ambient. Main technical parameters 1. Nominal load moment 2. Max. lifting height: a. Fixed: *8.*5m b. Attached: **0m 3.
