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:Tower crane (tower crane)
In the form of the structure for the tower type, flat type and movable arm type. The model can be divided into QTZ63 suspension, QTZ80 crane, QTZ125 crane, QTZ crane, 315 crane and so on according to the moment division. Now used to arm length + tip weight of the way named, for example, 5513, that is, the longest length of 55 meters arm, the tip of the largest weight of 1.3 tons.
Q:How to improve the stability of tower crane
The fatigue test data show that the fatigue life of the phosphating coating of steel wire rope is about 3 times of the same structure light steel wire rope (laboratory comparable conditions), not easy to wear and corrosion is not easy to cause the service life of wire rope large amplitude extension. Manganese phosphating is wear resistant phosphating, which can solve the wear problem in the use of wire rope and improve the corrosion resistance. It is for reference only
Q:How did the tower crane rise on the construction site? Fifteen
In the table below the tower crane is the upper part of the tower body has four jacks, the top of the cage tower (tower of each section is called a tower cage) a little bigger than the following (which can be installed under a small tower, heightening cage) need to jack up above "high rise to work, just a small tower added into the big cage, the cage towers bolted, or tall tower cage can be fixed.
Q:In what circumstances should a tower crane be demonstrated by an expert?
Circular of the Ministry of housing, urban and rural construction on Issuing the measures for the safety administration of sub hazardous and sub divisional projectsBuilding quality [2009]87 number]Annex twoMore than a certain size of the risk of larger sub sub project scopeI. deep foundation pit engineering......
Q:Which kind is better, gantry crane or tower crane?
Each has advantages, the use of different conditions, the use of different cranes, tower cranes can not move, but the lifting height can be very high, the door machine has tracks can be vertical and horizontal movements, lifting height, tower crane is not high.
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:What courses should I take to buy the tower crane to be installed?
First in the construction, some costs incurred during the installation, after installation costs together included in the original value of fixed assets.
Q:How many meters does the tower crane installation height require expert proof?
The installation, disassembly and jacking of tower cranes must be carried out by experts
Q:Tower crane four limit, two insurance, two insurance what is that?
Refers to the air switch and the electric leakage protector in the electric tray.
Q:What are the basic parameters of a tower crane?
The basic parameters of a tower crane include the length of the crane itself, the weight of the crane as well as the weight of the counterweight! Tower crane lifting mechanism; slewing mechanism; luffing mechanism; motor power;...
