Document Type and Number:
WIPO Patent Application WO/2016/129262
Kind Code:
A1
Abstract:
The invention addresses the problem of providing a car body weight supporting device to enhance orientation stability. A lower traveling body of a crawler crane comprises a pair of crawler frames on the left and right, a car body (32) that connects both crawler frames together and supports an upper rotating body, and a pair of car body weights (38, 39) that are provided in each side of the car body in the front and rear direction. A car body weight supporting device (50) comprises a supporting mechanism (51) to support at least one of the pair of car body weights so as to be movable, and a driving unit (52) to vary the position of the center of gravity (G) for the lower traveling body in the forward to rear direction by moving the car body weight (38) supported by the supporting mechanism.
