Product Description

Topless tower crane PT7030
Hoisting jibs have good applicability and efficiency. Design of flattop tower cranes is easy to realize modulization, this point is important. For manufacturers, hoisting jib modulization can reduce design and production costs, then can reduce prices of flat top tower cranes; For users, can make full use of agility and adaptility of hoisting jibs, if same types, different grades, hoisting jib sections can be used each other, end jibs of large capacity flat top tower cranes can be used as middle or root sections, so that can increase jib combination, improve applicability and efficiency of hoisting jibs.
Decrease design cost. Design of flat top tower cranes don't have design and calculation of tower head and pulling rod, less calculation work condition, simple mechanical model, calculation reduces that make results of calculation is closer to actual value, so that can be easy to proceed modular design, decrease time of design.
