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.

The crane has good applicability and high utilization rate. It is very important that the design of flat head tower crane is easy to realize modularization. For the manufacturer, the design and manufacturing costs can be greatly reduced by the modular boom, thus reducing the flat-head tower price; For users, can give full play to the flexibility and adaptability of the boom.

The flat-head tower crane arm section special connection way and does not have the tower head, the pull rod, makes its hoisting arm section by section disassembly very simple.

The boom steel structure has long life and high safety. The flat head tower is more stable than the ordinary tower crane, especially in the rotary or emergency braking,

The effective height of the hook is greatly improved, and the space utilization rate is high, so it is very suitable for the occasions with special requirements on height, such as the reconstruction and expansion of the airport, the construction beside the airport, the construction inside the tunnel and the factory building, and the construction under the high-pressure line, etc.

has the advantages of less total installation time, lower requirements for installation equipment, reduction of the weight of each tower crane and the use of smaller tower section and chassis.
