8ton 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.

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 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.

When installing the lifting arm of an ordinary tower crane, the boom and tie rod must be connected on the ground before overall hoisting. At this time, the requirements for lifting equipment are the highest, with great lifting weight and lifting height
