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.

Providing ample spare parts and training of operation and maintenance
Engineers have more than 20 years' experience in tower crane, ready to solve any of your problems.
Q: What kind of steel used for tower crane ?
A: Normally, as for the main force bearing steel structure, Q345B is adopted; as for the assistance force bearing steel structure Q235B is adopted. All of the raw material is outsourced from qualified steel factory in China.
Q: What about our tower crane warranty?
A: Usually there is one-year quality warranty including main electronic parts (not including consumable parts). There are consumable spare parts together with whole machine and normally they are enough for one year.
Q: What is 3 main mechanism of the tower crane ?
A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.
Q: Can you equip with light on tower crane jib, monitor, remote control and anemometer?
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: (a)What is the power output of the crane. (ignoring losses)?(b)If it takes the cran2 2 minutes to raise the payload to its final height, how far above the ground is this?(c)If the cable were to break as the payload reaches its final height, how fast would it be traveling as it hit the ground?
- a) As the crane is lifting at constant speed, there is no acceleration on the payload, therefore the net forces on the payload are equal to 0. Therefore the crane overcomes just the force of gravity = 500*9.81 = 4905 N Power = force * velocity = 4905 * 0.7 = 3433.5 W b) distance = speed * time = 0.7 * (2 * 60) = 84 m c) assuming that the cable breaks while it is still going up at 0.7 m/s, therefore initial velocity upwards = 0.7 m/s. using v? = u? + 2as: v? = 0.7? + 2(-9.8)(-84) = 1646.89 v = √(1646.89) = 40.9 m/s the payload will be travelling at 40.9 m/s when it hit the ground.
- Q: Please try to give information on the questions bellow: .What the climate was in the Japanese Crane's habitat (high, lows, averages, precipitation) . Plants in the Japanese crane's habitat .2-3 major animals in its habitat .2-3 minor animals in its habitatTHANK YOU SO MUCH!!! .
- in the east Hokkaido, the north island of japan. some japanese crane in russia goes to north korea in winter, but cranes in hokkaido stay all through the year.
- Q: expane the parts of crane?
- The spelling error is fatal: expane does not resemble anything that makes sense. At least two things are called a crane, one a machine and the other a bird. So you just need to rewrite your question so that it explains what you want clearly enough for somebody to look up an answer.
- Q: Wall mounted tower crane
- The construction of tower crane installation, operation and dismantling safety technical regulations "(JGJ196-2010) design provisions in article 3.3 attachment device of tower crane: when the tower crane attachment for use, attachment device settings and free height should comply with the provisions of the instructions; when the attachment level distance, attachment spacing does not meet the the instructions to.

- Q: Tower crane attached concrete pump can be? Are there any state regulations?
- Do not need to expressly can not tower crane work mode cannot withstand recoil thrust and level, and these forces or dynamic load, if the use of the tower crane is not an accident, almost impossible, then help the wall studs, will fall off, the consequences are not dare to think.
- Q: Military Action movie with bunch of cranes at the end?
