The Features of QTZ50(4810)
1): The main stressed steel parts ofQTZ50 tower crane use Q345B steel, the tower body mast section 1.62m*1.62m*2.2mor 1.62m*1.62m*2.5m.
2): Light weight, air resistance issmall, convenient transportation. Rotation adopts double rotaryorganization. Lifting mechanism is driven by frequency converted motor, runningsteady
3): It adopts standard section hydrauliclifting and connecting, and can decide the crane height according to the actualheight of the building
4): High-quality surface coating that canmeet different requirements of transporting and using. It is durable underenvironments of low, high, wet as well as oceanic environment
5): The crane has full set of safetydevices, which ensure the safe and high efficiency. It has liftingheight limiter, dolly range-change limiter, moment limiter, weight limiter,slewing limiter, etc
6): The coiling frequency motor andmono-speed ratio decelerator is applied in the lifting mechanism, which enablesheavy load low speed and light load high speed
7): The range-change structure drives thedolly to change range on the horizontal arm, with good positioning performance
8): Planet gear decelerator is used inthe slewing structure, together with moment-limiting hydraulic coupler,which ensure high load capacity, steady starting and reliableoperation
