Q:Type and specification of tower crane,
Big Han tower QTZ63 series mainly produces 5010, 5013 and 55105010 arm length 50 meters, arm tip bearing 1 tons, the basic height of 30 meters, standard section specifications: 16*2.5, 5013 arm long 50 meters, arm tip bearing 1.3 tons, basic
Q:What is a tower crane without a collector?
Once again, because the collector is using carbon brush and copper ring contact, the tower crane work in the sway of the impact is too large, easy to cause carbon brush and copper ring arc between burning. Combined with this reason, today's tower cranes do not use collector. The drawback is that the tower crane can not be one-way one-way rotation. So now the use of rotary limiter, set the tower one-way rotation can only turn 540 degrees, want to turn, can only turn in the opposite direction.
Q:All types of jack up cranes. How is the maximum lifting torque converted?
Tower crane lifting torque = crane maximum lifting weight * maximum operating range; for example: the maximum lifting weight is 2T*, the maximum operating range of 50 meters =1000KN.m.
Q:[tower crane] and [tower crane] what is the difference between, how to distinguish?
There are many nicknames for tower cranesTower Crane Tower Crane Tower
Q:What are the construction cranes? 50

Q:What are the safety devices in a tower crane?
(1) lift height limit position limiterFor cranes with variable boom angles, the lifting motion must be stopped immediately when the top of the lifting device rises to the 8OOmm at the lower end of the boom.For luffing cranes, lift the top of the hook to the lower end of the frame 500mm. The lifting movement must be stopped immediately.(2) lifting moment limiter and maximum lift limiter;When the lifting torque reaches 90% of its rated value, the lifting torque limiter shall be able to issue an acoustic or red light to indicate the alarm. When the lifting torque exceeds its rated value and reaches 108% of the rated value, the lifting direction and outward direction shall be stopped.If the weight and amplitude indicator are set, the numerical value should be correct, clear and eye-catching. The digital error shall not exceed 5% of the indicated value.When the lifting weight exceeds the maximum weight, maximum lifting weight limiter should emit light or sound alarm, when the load exceeds the maximum weight of 6%, should stop to enhance the direction of movement, but to allow institutions towards the down direction.(3) amplitude limiting deviceA crane shall be equipped with a minimum amplitude limiter and a device for preventing the boom from rebounding backward. The trolley must be equipped with a trolley switch and a terminal buffer.(4) rail clamping device and walking spacing deviceTrack type tower cranes must be equipped with rail clamps.
