Q:When the tower crane top height is more than meters
Three, lifting and installation, demolition works(1) lifting projects with unconventional lifting equipment and methods with single lifting weights of 100kN and above.
Q:What kind of personnel should be installed for the tower crane installation and disassembly?
According to GB specifications:2.0.3 the installation and disassembly of tower cranes shall be provided with the following personnel:1. The project and the safety supervisor and the mechanical management personnel who have the safety inspection certificate;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 special operators of tower cranes?
The tower has special operations personnel of heavy machinery refers to the construction site in the tower crane division signal cable, installation and disassembly, the driver, and the demolition work of gondola installation, may cause serious harm to themselves, others and the surrounding facilities operations personnel. Specific include construction lifting signal division, cable construction, lifting machinery, tower crane driver (T), construction crane, tower crane installation, demolition worker (T), and height job basket, installation, demolition workers.
Q:What are the construction cranes? 50
The most common are tower cranes, elevators, and freight lifts. The big construction enterprise also has the track type tower crane
Q:What kind of bodies are tower cranes made of?
Two. The metal structure of tower craneThe metal structure of tower crane is mainly composed of underframe, tower body, jacket, upper and lower support, suspension arm, balance arm, tower top and other main components.Metal structure is the framework of tower crane, which bears the deadweight of crane and all kinds of external loads during operation.Three. Power unit and control systemThe power unit is the power source of the crane, and the power source of the tower crane is an electric motor with an external power supply.The control system includes controls and safety devices. Control device for tower crane is composed of a linkage control console, distribution box, resistor box components, the safety device is mainly composed of height limiter, amplitude limiter, lifting weight limiter, moment limiter, slewing limiter etc..Through the control system, the movement characteristic of the crane can be changed, so as to realize the starting, speed regulation, modification, braking and stopping of each mechanism, so as to achieve various actions required by the crane operation.
Q:What is the scope of the installation and disassembly of self lifting tower cranes and the applicable range of the cost and the off-site transportation cost?
The installation and disassembly of the existing self rated tower crane, the first cost and the off-site transportation cost quota are divided by the lifting moment 1000kNm and 2000kNm of the jack up tower crane.
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 are the safety devices for the horizontal arm self lifting tower cranes?
(3) the amplitude limiting device shall be equipped with a minimum amplitude limiter and a device for preventing the boom of the boom from rebounding after the luffing of the jib. The trolley must be equipped with a trolley switch and a terminal buffer. (4) rail clamping device and walking limit device; track type tower crane must be equipped with rail clamping device. A walking limit device shall be installed at the same time. (5) a crane with wind point at the root of the boom with a height of more than 50m shall be equipped with an anemometer at the top.
Q:What is a TQ80 tower crane?
A full swing jib crane with a tower type structure, a crane that can travel along the track and is equipped with a full swing arm.
Q:What are the basic parameters of a tower crane?
The basic parameters of a tower crane include the length of the crane itself, the weight of the crane as well as the weight of the counterweight! Tower crane lifting mechanism; slewing mechanism; luffing mechanism; motor power;...
