摘要： An upstream cylinder (21) and a downstream cylinder (24) are fixedly mounted to a support member (19), and a filter cylinder (26) is provided mountably and dismountably between the cylinders (21) and (24). In consequence, only the filter cylinder (26) can be dismounted with the cylinders (21) and (24) left as they are on the support member (19), so that the maintenance operation of a particulate matter removing filter (28) can be performed easily. In addition, pressure conduits (32) and (33) and a pressure sensor (34) of a pressure detection unit (31) for detecting a clogged state of the particulate matter removing filter (28) are disposed at positions offset from a moving path (30) of the filter cylinder (26). In consequence, only the filter cylinder (26) can be easily mounted or dismounted without being obstructed by the pressure conduits (32) and (33) and the pressure sensor (34).

摘要： A hydraulic drive system for a working machine provides improved safety during forced regeneration. Upon input of a forced regeneration command signal from a forced regeneration switch, a controller detects non-operated states of all hydraulic actuators such as an arm cylinder arranged on a hydraulic excavator based on a lock detection signal from a gate lock detection switch, and also an attitude of a front working mechanism. The attitude is proper from the standpoint of safety. The detection is based on an arm angle signal from an arm angle sensor, a bucket angle signal from a bucket angle sensor and a boom pressure signal from a boom pressure sensor. Taking the detection of the non-operated states and proper attitude as conditions, the controller outputs control signals to a boosting proportional solenoid valve and flow-rate controlling, proportional solenoid valve to make a forced regenerator conduct forced regeneration.
