Description of TCD4021
1) CMAX TCD4021 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 measures should be taken to make tower cranes stable?
- Phosphating coating of steel wire rope, give priority to the use of manganese or zinc manganese phosphating, and smooth steel wire rope production process comparison, just add the last bonderizing process, steel wire, wear resistance and corrosion resistance is greatly improved, the use of the wire without direct phosphating cold twisted steel wire rope.
- Q:Four for crane, two for insurance, two for insurance. What does that mean?
- Four limit: torque, ultra high, variable amplitude, walking limit device. Two insurance: hook insurance and reel safety device.
- Q:How to distinguish self lifting tower crane with counterweight and lifting tower crane without counterweight
- 1 self lifting tower cranes with counterweight are common tower cap tower cranes, plate type tower cranes and flat head tower cranes, characterized by a counterweight made of several concrete on the balance arm,
- Q:Which is the main basis for the disassembly and assembly process planning of tower cranes?
- .0.11 tower cranes should be prepared before the installation of special construction program, and should include the following contents:1 project overview;2 installation location, plane and elevation;3 types of tower cranes and technical parameters of performance;4 basic and attachment device settings;5, climbing conditions and adhesion nodes detail;6 installation sequence and safety quality requirements;7 weight and suspension position of main mounting parts;8 installation of auxiliary equipment type, performance and layout;9 power settings;10 construction personnel allocation;11 rigging and special tools;
- Q:How about the installation and disassembly of the tower cranes?
- Authorized by the national security inspection department, the local special operations training school or the technical quality supervision bureau, after the study, assessment, qualification and graduation permit, will give you special operations installation, removal operation certificate.
- Q:How many meters does the tower crane installation height require expert proof?
- The mounting height of the tower crane is determined by the manufacturer's manual,It has nothing to do with experts,After the tower crane is installed, it needs to go through the provincial construction quality and safety supervision station, and the designated testing institution will meet the technical requirements of the production plant, and the method can be used only after the use of the permit.
- Q:Tower crane four limit, two insurance, two insurance what is that?
- Refers to the air switch and the electric leakage protector in the electric tray.
- Q:What is the difference between a tower crane and a jack up 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:What is a TQ80 tower crane?
- The concrete transport vehicle can be used at the lower part of the tower of the large tower crane. The one we usually see at the construction site is.) TQ80 is a model of cranes.
