Q:What does the lifting mechanism mean in a tower crane?
Magnification, in simple terms, refers to several ropes through the hookIf it is one in and out of two wire rope, that is two magnificationSimilarly, two into two out is four magnification
Q:Tower crane 4 how to change the rate of 2 magnification, how to change, say detailed points
There is a magnification pin on the hook group. When the magnification pin is removed, the pulley will automatically slide to the lifting trolley.
Q:Is a tower crane a fixed type crane? Still can walk? Thank you
The tower crane is the equipment that can be used in the construction site and is not to walk.
Q:How did the tower crane rise on the construction site? Fifteen
With a bar of steel, each layer has about 10 or more bars of steel. When the building rises, add a few more bars to the top floor, plus a few layers. It uses the stability principle of the triangle to keep the tower crane from tilting, and it also needs to pull some cables around to keep it balanced, just like a country pole.
Q:The earthing resistance of tower crane shall not be greater than that of the tower crane
Lightning protection grounding is less than 10, transformer grounding is less than 4, special equipment requirements is less than 1
Q:When the tower crane top height is more than meters
(two) lifting equipment installation with lifting weight 300kN and above; demolition work of climbing crane within height 200m and above.The installation and disassembly of the tower crane in accordance with the provisions of the above provisions shall be verified by the expert panel.
Q:What kind of personnel should be installed for the tower crane installation and disassembly?
2, with special construction operation qualification certificate of construction, lifting machinery, installation, demolition workers, lifting signal workers, lifting drivers, cable operators and other special operations personnel.And an electrician.
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. A walking limit device shall be installed at the same time.(5) anemometer;For cranes with a hinge height of more than 50m at the root of the boom, a anemometer shall be installed at the top.(6) lightning protection and anti electromagnetic wave induction device;For the crane whose hinge height is over 50m, the lightning arrester shall be installed according to the actual situation and the electromagnetic interference shall be taken.(7) tower crane shall install limit torque coupling in order to prevent slewing overload.
Q:What is the difference between a jack up tower crane and a fixed tower crane?
The jack up tower crane is a tower crane (that is an internal climbing tower crane) that is added and reduced by its own special device, namely, the standard section of the tower (that is, the attached tower crane) or the whole climbing tower itself.
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.
