Description of our Tower Crane

1) TC60/10 tower crane is one of the key product of CNBM company, which have competitive price and excellent quality, suitable for all kinds of construction project and can work under all kinds of work condition.

2) This kind of crane adopts standard section hydraulic lifting and connecting, and can decide the crane height according to the actual height of the building, and at the same time the lifting capacity will not be affected

3) 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.

The range-change structure drives the dolly to change range on the horizontal arm, 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 of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.

5)The machine has scientific layout and beautiful appearance. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.

Advantage of our tower crane
1, boom relief Angle is big, greatly widened the equipment capacity and scope of work.
2, suitable for the group of tower cross homework.
3, boom stability is good, combination amplitude range.
4, suitable for height have special requirements occasions construction.
5, lifting capacity big, effectively solve the high steel structure construction team crane big lifting capacity requirements.

Q: What makes a crane so strong?
Cranes are built using a structural technique called a truss which is characterized by looking like a series of triangles connected together. That structure prevents the members from having to resist any bending loads. All of the truss members experience only tension and compression, no bending. That is an extremely efficient structure which is why they can be so strong without being monstrously heavy. Or if you prefer the short answer, engineers make the crane so strong.
Q: What is the calibration value of a tower crane?
Do you mean the calibration value of crane lifting moment? That should be the product of the maximum magnitude of the tower crane and the corresponding maximum lifting load.
Q: What kind of equipment must be installed on luffing trolley of horizontal luffing tower crane?
It must be installed:To prevent the trolley cable broken car slip away;
Q: In the poem "The Wayfarer”, what is Crane's ironic comment on the pursuit of truth?
I am a big fun of Rayban as well. I always buy from this site...
Q: does anyone have a good slogan for the whooping crane?
Let the Whooping Crane do what it does best, make Whoopie!!!
Q: How to improve tower crane industry in china?
Powerful okorder ) manufacturing standards according to the rules of tower crane industry market economy. ?? Manufacturing industry is a huge system, the formation of a broad face, not one or two companies can do a good job. Powerful alliances to promote the group is a good idea, but it can not Arbitrarily arranged association, we must do things according to the market economy laws. A lot of problems are not necessarily be resolved by the professional industry, you can use the cross-industry solution.
Q: Hi there!I was planning on making an electromagnetic crane, and I already understand how the electromagnet works. Its for the science fair in two weeks, but they asked us to make our projects soon.But I not sure hot to build the crane itself, any ideas?
Here okorder / Hope that this gives you some ideas. Wingman
Q: dynamic force on crane when a load of 37k falls 1',2' 3'or 4'?
Need more information. In general, the answer is that the dynamic load depends on how quickly the payload decelerates. The dynamic load will be the mass of the payload times the peak deceleration rate. In a strength calculation, do not forget to include the static weight component of the load. The deceleration depends on the elasticity of the cables supporting the load. If the crane has a flexible supporting structure, then that could also affect the result. (You didn't say whether the crane is the traveling overhead hoist type usually seen in a factory - which typically has a stiff support - or the cantilevered truss type seen on construction sites - where the support might have a little flexibility.)
Q: What is the allowable range of vertical deviation for tower cranes?
The specified installation, construction, demolition of tower crane safety technical regulations in JGJ196--2010: the allowable deviation of verticality Tower: in the wind under no-load, the tower axis line should be less than 4 per thousand of the bearing surfaces of the lateral vertical deviation; after the attachment, the highest attachment point following the vertical deviation should be less than 2 per thousand. According to the installation state of tower crane, the deviation range of verticality is divided into 4/1000 or 2/1000. Tower crane maximum independent installation height (maximum installation height, does not need to be attached to the wall of the instructions specified in the free end) and height (the highest point of a tower crane attached to the wall above the height, body the following provisions in the specification of tower crane slewing) the vertical deviation range was 4/1000; tower crane attachment verticality deviation below the allowable range is 2/1000.
Q: How much is a team of 40 tower crane
Tower crane rental generally do not rent pricing, can not count number, not today is installed, removed tomorrow!Usually on a monthly basis, with or without use!
