Main Features of Tower Crane
1) This kind of crane adopts standard section hydraulic lifting and connecting.The max. height can reach 180m with wall tie ins.
2) 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.
3)The range-change structure drives the trolley moving on the horizontal crang jib, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.
4) The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation. The crane is equipped with lifting height limiter, trolley ranging limiter, moment limiter, weight limiter etc..
5)The cranehas scientific layout and handsome appearance. The drivers cab is set independently on one side, with good vision field. It creates a good working environment for the operator.

A: Sure. All of these could be provided with extra cost upon the clients' requirements. But according to general practice, remote control is not suggested because most of the operator feedback operation in the cabin will provide a wide working view.
- Q:What prior education and skills are needed to become a Crane operator ?
- idk
- Q:What is the book about?Is it a good one?
- that was a really good book about a girl who gets leukemia and thinks that if she makes 1001 cranes she'll get a wish and live on but sadly she dies. her classmates finish the paper cranes and they made a statue in her honor.
- Q:please tell me thats not what i think it is O_O
- there is cow hoof protein in mascara
- Q:A family of cranes are at my house they are attacking my ducks and im scared they will kill them
- If your ducks are running loose and not in a wildlife proof pen, you are just asking for them to be harmed, harassed or eaten by just about anything. Keep your ducks in a safe place and you will not have a problem. ALL wild native birds are protected by law and definitely have more rights to be in nature than domesticated ducks do.
- Q:HSE Officers can better answer this question or a qualified Crane operator it self can explain.
- each crane is so different. it depends on the rated crane load, the lifted distance from the crane and actuall load to be lifted. Each crane an envelope of angles to the horizontal, lifted load, and distance from the crane. The crane operator must insure that he is within this envelope or the crane may topple over. Also, the wind at the time of the lift must be considered. If you can picture a seesaw with loads pivoting about a fulcrum. When two people are on the seesaw, one person is the crane and the other is the load to be lifted. Only in the case of a crane, the fulcrum is at the crane itself with a large dead load counter weight behind the cab operator.
- Q:Any difference?
- The crane part can be identical, but the vehicle part differs: in the former case it's a road-going (even multi-axle) truck, in the latter case it's an off-road vehicle with oversize all-terrain tires and appropriate traction and transmission capabilities. In either case, the vehicle must be stabilized on adjustable hydraulic struts before hoisting.
