Q:What special operators should be equipped for the installation and disassembly of tower cranes?
According to the requirements of the 2.0.3 specification: tower crane tower crane installation and disassembly operation should be equipped with the following: 1, hold a qualified safety assessment certificate of the project and responsible for the safety of people and machinery management personnel; 2, with construction qualification certificates for special operations of the construction hoisting machinery installation and disassembly, lifting work, special operation signal heavy drivers, riggers and other operations personnel. And an electrician.
Q:In what circumstances should a tower crane be demonstrated by an expert?
Three, lifting and installation, demolition works(1) use of unconventional lifting equipment, methods, and lifting weights of a single piece in excess of 100kN and aboveHeavy lift works.
Q:Tower crane and tower crane 5
Vertical transportation can be done with elevators, construction lifts, and Longmen racksTower cranes and tower cranes are one thing
Q:What does "automatic tower crane" mean less than 100 tons per metre?
The crane must not exceed the maximum lifting capacity when working! Otherwise, there will be danger.
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.
