Usage/Applications of TC4808
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 requirements for jack up and plus section of jack up tower crane?
- When lifting, a standard section is hoisted on the imported beam or introduced platform. Then open the pins or bolts connecting the standard section with the slewing support. Start the oil pump, so that the cage in the standard section of the outward sliding, until the release of a standard section position, and then imported beam or imported platform on the standard section into the connection. This completes a process.
- Q:About tower crane torque limiter with 4 limit switches, each play a role, thank you
- Lifting weight limiter: limit maximum lifting weight;Torque limiter: limit the maximum lifting torque;Height limiter: limits the maximum and minimum position of the hook lifting and lowering;Amplitude limiter: limit the lifting trolley in the boom on the outside, the inside position;Slewing limiter: limit of up to the number of rotating ring arm;
- 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:Four for crane, two for insurance, two for insurance. What does that mean?
- Refers to the air switch and the electric leakage protector in the electric tray.
- 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;
- Q:Is it difficult to test tower cranes?
- A tower crane installation scheme, 1, compilation basis, project overview, working environment, 2 workers and 3 endurance calculation and installation equipment for 4, installation procedures, methods and requirements for 5, commissioning record 6, two safety technical measures, safety technical disclosure, three installation foundation concrete test report of four, the tower crane installation and acceptance of table five, safety supervision station issued a permit for six, seven, demolition demolition project safety technical clarificaiton tower crane installation scheme project name: preparation: position (title): Approval: job (title): the construction unit: tower crane installation demolition project, the preparatory work before construction: 1. The tower crane installation position, according to the effective range of the construction requirements, site conditions and the role of tower crane, convenient installation and disassembly, the tower crane configuration in 17 axis to 18 Between the axis, away from the outer wall of 5 meters, with 11 standard section. 2, the basis of the principle, the use of concrete foundation, strictly according to random basis drawing. 3, the examination of concrete pressure report, tower foundation has been completed by design and construction, the safety group acceptance, the basic test block delivery, after the test pressure qualified, must be installed. 4. The installation site is level and the channel is repaired. 5, transport parts admission
- Q:What are the types of cranes?
- Two, crane according to the structure is divided into bridge crane and jib crane two categories. (1) traffic, metallurgy specialcrane and Longmen crane, cable crane is a crane (2) portal crane, tower crane, truck crane, crawler cranes, truck cranes, cantilever crane is a crane arm.
- Q:Is tower crane a tower crane?
- Yes, the tower crane is commonly known as the "standard" in the industry. It is called tower crane.
- 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:Under what circumstances does a tower crane require third party testing?
- New clothes, relocation or transformation should be examined by the quality and Technical Supervision Bureau
