Tower Crane

ZCJJ Luffing jib tower crane take advantage of technology from France, Germany, Spain, Italy and other foreign advanced countries, combined with the national standard of tower crane, design and produce various types of tower crane

convenient to dismantle and install the tower crane under the limited condition of the construction site.
If limited by the field conditions,
the flat tower is undoubtedly the best solution when the truck crane cannot approach. Because of the unique boom connection mode of the flat-head tower, the whole boom can be disassembled and assembled in the air section by section, and the boom can be directly removed from the transport vehicle when necessary.

The boom section usually has 4m, 5m or 10m sections. Taking the 50m lifting boom as an example, its maximum unit mass is only about 1/5 of the total amount of lifting boom. Compared with the whole lifting, the lifting equipment required by the disassembling and assembling of the boom in air section by section is greatly reduced, which not only saves the cost of disassembling and assembling, but also is safer and faster.

Derrick crane again USES the lifting handle pole or the small lifting machinery to unload, the rest USES the construction elevator to unload

Luffing jib tower crane,The boom of movable tower crane fluctuates from 17 to 83 degrees, which greatly broadens the capacity and working range of the equipment. Compared with the horizontal arm tower crane,

Luffing jib tower crane the large elevation Angle of the lifting arm is equivalent to the increase of the height of the tower body, and the effective extension of the working range is almost the semi-sphere space with the length of the lifting arm as the radius.

Luffing jib tower crane,This is of great significance for the construction of the main structure and the hoisting of the towering components on the main structure.
The tail turning radius is between 8 and 11 meters, which provides more options for tower group operation and construction in narrow urban working space, and is even the only choice for construction of super high-rise buildings in the central area of the city.
But on the other hand, due to the lifting boom fluctuation caused two problems. First, the gravity bending distance of the boom changes greatly
6Ton to 12Ton Luffing jib is our main products.

Topless tower crane and Topkit tower crane each have their own scope of application, therefore, in the actual construction process, because the construction of material is crucial

Low design cost.
The design of flat-head tower saves the design and calculation of tower head and pull rod, and the calculation condition of lifting arm is less, the mechanical model is simple, the calculation amount is greatly reduced, the calculation result is more close to the actual value, convenient for modular design, thus greatly reducing the design cycle.
