Description of  TOWER CRANE TC5013

1) CMAX TC4808 tower crane is one of the key product of CNBM company, which have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.

2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected;

3) It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.

4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.

5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator

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 requirements for jack up and plus section of jack up tower crane?
Shall conform to:1, tower crane has not reached the standard free height or attachment, not to the standard suspension height;2. The standard section of tower crane jacking must be the size of the original production;3, tower crane jacking work must be carried out by the professional installation team;4 tower crane jacking up, the wind must be less than four.Answer the 1 floor:The height of the self elevating tower crane is built up by other cranes like building blocks.
Q:What is the torque limiter of the tower crane A: the lift is stopped when the lifting torque is exceeded. B: over gravity
The torque limiter acts as follows: (a)In lifting process, when the weight of the lifting object moves ahead of the trolley when the lever force exceeds the moment limiter, the hook rises, the motor and the trolley forward motor are stopped at the same time, and the utility model has the safety function.
Q:What should the sub contractor do before the installation of the bridge crane in the workshop?
Baidu search [tower crane tower demolition, lowering section safety technical disclosure]. If it is installed, remove the "two words" to "installation", and other contents are adjusted slightly.
Q:What is an attached tower crane?
Attached tower crane is due to the height of the building is relatively high, a steel connection in order to strengthen the stability of tower crane between tower crane and tower crane building, this form is called the attached tower crane.
Q:How many tons of tower crane QTZ80A lifting?
Lifting torque = mass * radius of gyration (amplitude). That is to say, the bigger the weight is small.
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:Can the tower crane personnel install the construction elevator?
Although it belongs to the construction of special operations, but the operation of different categories, tower crane demolition workers according to the requirements can not install the elevator!
Q:What is the inspection certificate for tower cranes?
Inspection certificate of tower crane must have two certificates:1, the manufacturer issued its own "product quality certificate"2. The product quality supervision and inspection certificate issued by the Technical Supervision Bureau
Q:How much height should tower crane work at M?
High building one meter high voltage line to keep the relevant national standard to ensure the forearm and the adjacent adjacent tower crane tower crane standard section has a safe distance of 2 meters, big boom high high tower mechanism area covering more than one meter, the end will need to receive from the nearest cab hook.
Cranes and lifts are widely exported to Russia, Vietnam, India, Iran, South East Asia, Latin America, Africa and other countries and regions. Group's production capacity is more than 2500 sets, the production and sales are more than 500 million yuan, the exports are more than 15 million yuan!
