1.What is tower crane?

Tower crane is a modern form of balance crane that consist of the same basic parts Fixed to the ground on a concrete foundation (and sometimes attached to the sides of structures as well), tower cranes often give the best combination of height and lifting capacity and are used in the construction site.

2. What is the meaning of the tower crane’s code?

Take Tower Crane TC4808  for example, the first two letters “TC” means Tower Crane, “48” means jib length is 48 meter, and the last two letter “08” means the tip load is :0.8 ton.

3. What is the principal to quote the right tower crane to the client?

First, we need to know clients’ requirements,for example, max lifting capacity, height, tip load and jib length.. Second, we need to know what the foundation requirement from the client is and Third if there are special needs. CNBM could suggest proposal according to clear data provided by the clients.

Q:Type and specification of tower crane,
Type of tower craneAccording to the Ministry of construction ZBJ04008-88 "building machinery and equipment product model preparation method", the tower crane model composition as follows:QTZ, 80H, QTZ------ group, type, characteristic code80------ maximum lifting torque (ton M.)H------ update, variant codeAmong them, the updating code name is expressed in Chinese phonetic alphabet (upper case printed); the main parameter code is expressed in the Arabia numeral. It is equal to the rated lifting torque of the tower crane (unit kN * m) * 10-1;Group, type, characteristic code meaning is as follows: rotary tower crane on QTQTZ slewing tower craneRotary tower crane under QTAQTK rapid installation tower craneQTP climbing tower craneQTG fixed tower craneQTQ automobile tower craneQTL tire tower craneQTU crawler tower craneIn addition, now some tower crane manufacturers, according to foreign standards, with tower crane's largest arm length (m) and arm end (maximum range) can lift the rated weight (KN) two main parameters to mark tower crane model. Such as "QTZ100" in another mark "TC5613", its significance:T C 5613 T------ crane English first letter (Crane) C------ tower English first letter (Tower) 56------, maximum arm length 56m 13------ arm, lifting weight 13KN (1.3 tons)

Q:What is the insulation resistance of tower crane?
Two. Safety regulations for tower cranes GB 5144 - 20068.1.3 tower crane metal structure, track, all electrical equipment metal shell, metal line pipe, safety lighting transformer, low voltage side should be reliable grounding, grounding resistance is not more than 4 ohms. Repeated earthing resistance is not greater than l0. The selection and installation of the earthing device shall comply with the relevant requirements of the electrical safety.The insulation resistance of the 8.1.7 main circuit and control circuit shall not be less than 0.5M ohm.
Q:Under what circumstances does a tower crane require third party testing?
New installation, demolition, close, major transformation, the use of site work committee, the use of factories to the Technical Supervision Bureau
Q:How to build a tower crane?
7, the boom of the horizontal installation, setup of counterweight, main hoist installation, installation sequence of these large, there are provisions in the instructions.8 、 install operating room, main cable and control cable. Installation of crane wire rope, hook, lifting the car has been in the assembly of the boom when installed.9, at this time has completed the basic installation, the later self lifting installation, the main work by the tower crane itself equipment and artificial to complete.10 tower crane from basic height to work height.Each type of tower crane has different self lifting mounting methods. In fact, in addition to carrying heavy loads, the installation of a large number of high-strength bolts is a heavy work.11, the above is the general procedure, the actual installation work in strict accordance with the installation instructions. According to historical experience, tower crane installation accidents often occur in some professional installation team.12, the old type of tower crane installation is relatively simple, but also have independent installation, and now the development of automobile crane is not a must, general use of car crane can complete all the installation.
