Luffing jib tower crane
Introduction to large luffing jib tower cranes, which are no longer bottom-slewing, non-self-elevating luffing jib tower cranes in the traditional sense, but represent large lifting capacity, large lifting height, and large lifting capacity. Contemporary heavy construction crane with speed. The boom design of large luffing jib tower cranes adopts a rod structure, which has better structural stability than the beam structure of horizontal jib tower cranes. The boom structure accounts for a smaller proportion of the overall machine structural weight, and the maximum lifting capacity is larger.
Functions of luffing jib tower crane
In addition to the functions of external climbing, internal climbing and walking, the luffing jib tower crane also has the following functions
Modern large lifting capacity
Modern large-scale construction projects adopt For steel or steel and concrete composite structures, the weight of the hoisting unit is greatly increased. Special-shaped and composite structures usually reach a maximum ton and a surplus of tons. Therefore, large luffing jib tower cranes are equipped with heavy-duty main hoisting systems, and the maximum lifting capacity is usually up to ton.
Large lifting height
Due to the use of a special climbing system, the crane can climb with the entire building structure, and the lifting height is greatly increased.
High lifting speed
The lifting structure has high power, especially the self-prepared internal combustion engine drag scheme, and the lifting speed with load exceeds //.
