Q:what is the load combination with crane load and seismic load according to asce?
Asd Load Combinations
Q:how to pass a crane practical test?
Study or cheat.
Q:what is crane rigging?
Crane rigging usually refers to the cable that actually is attached to a cylinder in the crane and the motor turns the cyl. and either take up cable or vice versa. The cable is reeved thru the long (arm) boom of the crane and thru pulleys and then at the end of the cable there is a hook.
Q:Under what circumstances does a tower crane require third party testing?
New installation, demolition, close, major transformation, the use of site work committee, the use of factories to the Technical Supervision Bureau
Q:Tower crane 5610 why call QTZ63 tower crane, 5613 call QTZ806015, call QTZ100
As for the calculation method, the weight of a simple arm length * arm tip can not be used, because the nominal lifting torque of the tower crane is not calculated at the maximum amplitude.However, the maximum weight can be calculated by the maximum amplitude of the maximum weight, such as 5613 tower cranes, the maximum lifting capacity of 6 tons, while the maximum variable distance of 6 tons reached 15m, 60KN * 15m=800KN.m.The above is only my personal understanding of the tower crane, but I am not a professional construction machinery, the above calculations do not know whether it is reasonable, I hope to help you.
Q:What is the purpose of the stinger on Crane Flies?
ovipositor?
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.
