QTZ50tower crane belongs to upper-swing hydraulic climbing tower crane with horizontal-jib, winch-jib.Its main characteristics are as follows: All kinds of performance parameters and technical items are up to or better than the National Standard. The rated load moment is 580kN.m .The effective working radius is from 3m to 50m. The max.rated load capacity is 4t.The max.working radius is 50m.The freestanding hoisting height is 29m.The attaching hoisting height can be up to 120m. The tower crane has steady working, high speed and frequency. Low speed for heavy load and high speed for light load are used in lifting mechanism.Trolley mechanism has three speeds that can meet the working requirements.Slewing mechanism is equipped with normally open stopper that can make the tower crane take its place accurately for safe operation conveniently. QTZ50 tower crane is equipped with all kinds of safety devices, including weight limiter, load moment limiter,height limiter,slewing limiter,grip block and trolley brake,etc,which are all mechanical or Mechanical & Electrical Integration products,sensitive and reliable,which can adapt to bad construction environments and ensure the safety and reliability of the tower crane working.At the same time it is equipped with rest platform and guardrail,etc,labor and safey protective facilities for protecting the assembly,disassembly and inspection of the tower crane and the driver''s personal safety when moving up and down.
