发明名称 Hydraulic traveling vehicle
摘要 A hydraulic traveling vehicle includes a right-travel motor a left-travel motor, a hydraulic pump, a merging/diverging valve and a travel switching unit. The merging/diverging valve is configured to switch between merging and separating a first hydraulic circuit and a second hydraulic circuit. The travel switching unit is configured to switch between a state where sharp turning takes place as a result of one of the right-travel motor and the left-travel motor being stopped and the other being driven, with the merging/diverging valve being in a merging state, and a state where gentle turning takes place as a result of the right-travel motor and the left-travel motor being driven at different rotational speeds, with the merging/diverging valve being in a diverging state.
