SUPPORT DEVICE FOR WALKING MACHINES

摘要

A support device for walking machines comprises a frame-like base (5) connected to a chassis (11), sheathe tubes (3,4;9,10) fixed on the frame-like base (5), extensible arms (2) provided in the sheathe tubes (3,4;9,10), support parts (1,7) provided on the outward ends of the extensible arms (2) and extensible perpendicularly. The sheathe tubes (3,4;9,10) are arranged in double X-form. One pair of sheathe tubes (3,4) arranged diagonally to each other are parallel and at same height. The other pair of the sheathe tubes (9,10) arranged diagonally to each other are also parallel and at same height. The other pair of the sheathe tubes (9,10) are arranged at different height with one pair of sheathe tubes (3,4). A concrete pump vehicle using the support device according to the invention is more compact, more stable and can wok in limited space.
