The structure of the crane truck mounted crane

Truck  overhead gantry crane  structure is divided into: 1, crane boom and telescopic mechanism; 2, luffing structure; 3, the operating room and operating structure: 4, rotary structure; 5, turntable; 6, hoisting mechanism; 7, chassis ; 8 legs; 9, slewing ring.
Truck crane jib Category:
One, given the long arm truck mounted crane lattice boom with a fixed length, mostly for small mechanical transmission cranes, used car universal chassis, all the power is supplied by the vehicle engine, the engine does not separate. Boom angles and steel plate welded into use, was folding arm-shaped, in order to increase lifting amplitude.
2, then the long arm of the  bridge gantry crane  truck mounted crane is truss structure, composed by a number of arm, sub-base of the arm, the top arm and insert the arm. As needed, to change the boom length shutdown. Since truss force is good, the frontal area is small, light weight, it is the large-tonnage truck mounted crane unique structure.
3, telescopic hydraulic crane truck mounted  hoist gantry crane  structure is characterized by a box-shaped cross-section of multi-section telescopic boom from each other, the use of arms mounted on the hydraulic cylinder can be simultaneously or by-section telescopic or retract fully retracted when , the shortest arm, you can have the largest weight: fully extended, the arm up, you can have a maximum lifting height or working radius. Such products has developed into a major center of the tonnage truck mounted crane species.
