HYDRAULIC WORK MACHINE

PROBLEM TO BE SOLVED: To provide a hydraulic work machine that has a hydraulic circuit for emergency escape applicable to two types of emergency escape devices.SOLUTION: A hydraulic work machine has a supply pipe connection circuit 21 and a hydraulic oil suction connection circuit 25, which are applicable to a first emergency escape device 31 that uses a hydraulic oil in a hydraulic oil tank 18 of the hydraulic work machine when the hydraulic work machine such as a pile driver 11 is made to escape. The hydraulic work machine also has a supply pipe connection circuit and a return pipe connection circuit 23, which are applicable to a second emergency escape device that uses the hydraulic oil in the hydraulic oil tank of the emergency escape device.SELECTED DRAWING: Figure 1 【課題】 ２種類の緊急脱出装置のいずれにも対応可能な緊急脱出用油圧回路を備えた油圧式作業機を提供する。【解決手段】 杭打機１１などの油圧式作業機を脱出させる際に、油圧式作業機の作動油タンク１８内の作動油を使用する第１の緊急脱出装置３１に対応した供給配管接続回路２１及び作動油吸込接続回路２５を備えるとともに、緊急脱出装置の作動油タンク内の作動油を使用する第２の緊急脱出装置に対応した供給配管接続回路及び戻り配管接続回路２３を備えている。【選択図】 図１
