摘要 |
<p>A working machine where a boom control circuit (45) for controlling operation fluid to a boom cylinder (8bmc) is provided independently of and separately from a traveling/stick/bucket control circuit (25a) for controlling operation fluid to traveling motors (2trL, 2trR), a stick cylinder (8stc), and a bucket cylinder (8bkc). In the boom control circuit (45), there is a pump (84) for a boom, an energy recovery motor (86) is provided in one return path (56) where return fluid from the boom cylinder (8bmc) flows, a motor/generator (87) for the boom is connected to the energy recovery motor (86), and the pump (84) for the boom is connected to the motor/generator (87) through a clutch (88). Since the boom control circuit (45) is independent, a flow rate required by the boom control circuit (45) can be easily obtained.</p> |
