Tower Crane TC4808 FAQ:

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:All types of jack up cranes. How is the maximum lifting torque converted?
Tower crane lifting torque = crane maximum lifting weight * maximum operating range; for example: the maximum lifting weight is 2T*, the maximum operating range of 50 meters =1000KN.m.
Q:Why are there extra placards attached to the tower crane tower?
2. after adding the placard, it will increase the windward area of the tower crane and increase the wind load of the tower crane, so that it will deviate from the calculation load when the tower crane is designed, and will affect the safe use of tower crane.
Q:What is the insulation resistance of tower crane?
Three. Technical specification for temporary power safety on construction site JGJ 46-20055.4.2 within the construction site crane, derrick and Longmen machinery equipment, metal structure and steel scaffolding and under construction in construction projects, when lightning protection devices in adjacent buildings, structures and other facilities outside the protect zone of lightning arrester, lightning protection device should be installed in accordance with the provisions of.5.4.7 lightning protection electrical equipment machinery, connected to the PE line must repeat grounding at the same time, with a repeat of the mechanical and electrical equipment grounding and lightning protection grounding machines can share the same grounding body, but should be consistent with the repeated grounding resistance of grounding resistance requirements.The electrical equipment of 9.2.1 tower crane shall comply with the requirements of the current national standard "safety regulations for tower cranes" GB5144.9.2.2 tower cranes shall be subjected to repeated earthing and lightning protection grounding as specified in Clause 5.4.7 of this code. The earthing device of the track type tower crane shall comply with the following requirements:L the two ends of the rail are respectively provided with a grounding device;The joint of the 2 track is electrically connected, and the ends of the two tracks are electrically connected in the loop;3 long track every is not more than 30m and a grounding device.
Q:Emergency treatment of interrupted electricity during lifting of tower crane
The rotating gear shall be immediately inserted into the screw or wood, while the power supply shall be checked rapidly to remove the trouble.
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 are the types of common tower cranes?
Tower crane, tower crane. Tower crane according to its different types, there are the following classification methods.(1) according to the structural typeThe fixed tower crane by connecting a fixed tower in the foundation or structure, tower crane lifting operation.Mobile tower crane: a tower crane with running device and can walk. According to the running device, it can be divided into rail type, tyre type and caterpillar type.
Q:What is the definition of lifting, slewing and luffing of tower cranes?
Rotary is cantilever tower crane tower crane rotary shaft winding;Is the hook shaft distance amplitude change;
Q:Minimum QTZ63 tower crane special electric box open for many A
