Tower Crane TC7021 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 TC7021 for example, the first two letters “TC” means Tower Crane, “70”means jib length is 70 meter, and the last two letter “21” means the tip load is :2.1 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:why does the power company use helicopters to service the repair lines instead of trucks with tall cranes?
- High-tension lines operate at hundreds of thousands, or millions, of volts. At this potential, electricity can jump through several feet of air to reach a path to ground. This pretty much rules out using trucks, because it would be prohibitively expensive or impossible to build a crane out of entirely non-conductive materials. A helicopter is electrically isolated from the ground, so it's less difficult to drop a technician off and let him hang from the line itself while working. (It is still necessary for the technician to use a wand to bring the helicopter to the line's potential before starting work, because of the capacitance of the helicopter's body.) They could of course use a truck to service the lines if the power was disconnected, but the cost of shutting down service to an entire region of the country exceeds the operating cost of a helicopter.
- Q:I alsways see projects where there are these massive cranes sitting on top of huge buildings...how they hell do they get them up there?
- The big tower cranes you see on high rise structures actually....lift themselves. Their bases sit inside square lattice support structures and can climb them. When they get to the top of the structure they raise two more half squares that are bolted together around the base of the crane and the crane can then climb into the higher structure. The process is repeated until they get to the height limit of the crane. It's pretty amazing. Sometimes the crane base remains at the bottom, but sometimes, they close the floor below and remove the base that is no longer used, and just march the whole crane up the floors. Smaller cranes can be lifted by mobile cranes that go elsewhere, but the big ones use the method above.
- Q:Cranes nowadays are MASSIVE! but something that has been bugging me for ages is how do they get the massive crane bit at the top down once they have finished constructing the skyscraper/building?

- Q:Flocks of cranes shout'. Is it right to use the word'shout' here?
- No, it's not. First, the collective noun for cranes—its term of venery—is either herd or sedge, not flock. Second, the sound a crane makes is a whoop, or when not a whoop but a rattling sound, it is a bulge, not a shout.

- Q:I am making a crane(jib) whatever you call it and I have a concept for the crane itself but not for how I will actually move the camera. I heard wires work but I can not seem to grasp teh concept.* It is a heaver camera by the way*
- On a real camera crane you would press the up and down button that moves the wrist part of it. ( I drove a forklift). If you are doing to yourself you'll have to rely on the elbow movements. I might think about renting a Genie lift. And letting someone be your hands in the thing. Unless you know how to build a fully articulating hydraulic ball-joint?
