We are supply hydraulic self-erecting tower crane with upper slewing, horizontal jib and trolley mechanism. Its rated nominal

lifting moment is 1250kN•m,

freestanding height is min.27m, max Lifting height can reach up to 183m after being tied in wall, max.Lifting capacity is 14t,

lifting capacity with max.Radius is 1.5t and max. Work range is max.70m. The tower crane has become ideal construction mach

inery for all the construction companies because of its reasonable design, attractive appearance, superior quality and reliable

safety. All model of tower crane can be widely used in huge buildings construction with tower-shape structures such as high-rise

hotels, residential buildings, high-rise industrial buildings, large-span industrial premises, tall chimneys and warehouses.

     New type of construction tower equipment that is researched and designed by Institute of Building Mechanization of China

Academy of Building Research based on large formwork construction technology. It has the following characteristics:

1) Lifting multiplying factor switchover automatically, without operator's intervention.

2) Ahead of all domestic competitors,   we are the first manufacture to adopt lifting rope verticality limit mechanism, which decre

ases the lifting rope vertical angle under free load lifting mode, and highly improves the tower crane steering performance.

3) Our tower sections are exchangeable with the POTAIN H3/36B tower sections, which provide our customers more conveniences.

4) We adopt to use Dual drawbars structure on lifting boom, which enables the lifting boom to be under no stress at lifting surface

other than uniaxial stress, and moreover, it gets rid of the stress peak. It greatly improves the fatigue safety performance of lifting

boom.

5) Adopts VVVF stepless speed variation device for lifting, radius changing and slewing mechanisms, to make sure it works steadily

and effectively, it also lowers the maintenance cost.

6) The equipment adopts to use non-contact computer control system, which provides the high reliability and full functions to avoid

drivers' miss-operation.Our
