HYDRAULICALLY-POWERED WORKING VEHICLE

摘要

PROBLEM TO BE SOLVED: To achieve a structure, in a hydraulically-powered working vehicle, to bring about cost reduction and reduction in power loss and also to carry out operation using a turning section smoothly and in a short time.

SOLUTION: A backhoe, which is the hydraulically-powered working vehicle includes: an upper structure which is provided at an upper side of a travel unit so as to turn; and a hydraulic circuit 244 for the working vehicle. The hydraulic circuit 244 has: a first actuator group 246 including a left side traveling motor 34a; a first hydraulic pump 74 for driving the first actuator group 246; a second actuator group 248 including a right side traveling motor 34b and a turning motor 16; and a second hydraulic pump 82 for driving the second actuator group 248. The second hydraulic pump 82 is set so that a maximum value for discharge capacity per unit time becomes larger than that of the first hydraulic pump 74.
