A working machine includes a machine body, an operator's seat mounted on the machine body, an exterior cover positioned on a side of the operator's seat, and a handrail positioned with the exterior cover on the same side of the operator's seat and attached to the machine body. The exterior cover is fixed to a fixing unit included in the handrail.

A cable support device (14) for supporting an intermediate part of a power supply cable (13) is provided with a cable stand (16) attached to an upper revolving structure (3), an arm member (19) that is rotatably attached to the cable stand (16) to grip the power supply cable (13) on the tip end side and, and a locking mechanism (25) that is removably disposed in the cable stand (16) and in the arm member (19) to prohibit rotation of the arm member (19) relative to the cable stand (16). Thereby, the rotation of the arm member (19) relative to the cable stand (16) is prohibited by the locking mechanism (25), making it possible to prevent the power feeding cable (13) retained in the arm member (19) from contacting a cab (6).

A working machine includes: an operator’s seat; and at least one pedal to be operated by being stepped on with a foot, or with feet. The at least one pedal is disposed ahead of the operator’s seat. The at least one pedal includes a pedal body extending in a predetermined direction, a pedal shaft having an axis intersecting the predetermined direction and supporting the pedal body in such a way as to allow pivotal motion of the pedal body around the axis, and a tread surface provided on an upper surface of the pedal body and being a surface on which an operator places the foot. The tread surface is sloped such that a height from the pedal body decreases gradually from a portion closer to a big toe of the foot of the operator placed thereon toward a portion closer to a little toe.

A routing-member guide structure includes a movable member pivotably supported by a fixed-side member; a first routing member routed on or along the movable member; and a guide member to guide the first routing member. The movable member includes a first wall portion and a second wall portion facing each other with an interval therebetween. The guide member is inserted, in a direction intersecting the extending direction of the first routing member having been routed between the first wall portion and the second wall portion, into a space between the first wall portion and the second wall portion and is fixed to the movable member so as to guide the first routing member between the first wall portion and the guide member.

To ease work of transferring a fuel from a fuel supply tank to a fuel tank, a fuel supply guide to be used to supply the fuel by using the fuel supply tank to the fuel tank having a tank body for storing the fuel and a fuel supply port on the upper side of the tank body includes a support member provided on an upper portion of the fuel tank, and a body member projecting from the support member in a direction away from the fuel supply port as the body member extends upward and projecting higher than the fuel supply port. The body member is capable of receiving the fuel supply tank by an upper portion thereof to support the fuel supply tank.

A working machine includes a machine body, a first hydraulic actuator mounted on the machine body, a first control valve that controls the first hydraulic actuator, a controller that controls the first control valve, and a second hydraulic actuator that is different from the first hydraulic actuator. When the second hydraulic actuator and the first hydraulic actuator are operated in combination, the controller reduces the amount of change in the flow rate of a hydraulic fluid supplied from the first control valve to the first hydraulic actuator with respect to changes in a manipulation amount to operate the first hydraulic actuator to a value smaller than that when the first hydraulic actuator is solely operated.

A hydraulic system for a working machine, the hydraulic system includes: a hydraulic fluid reservoir; a boom actuator having an ascending chamber and a descending chamber; a first pump; a first directional control valve comprising a first ascending state configured for moving the boom in the ascending direction, a descending state configured for moving the boom actuator in the descending direction, and a first neutral state; a second pump; a second directional control valve comprising a second ascending state configured for moving the boom actuator in the ascending direction, and a second neutral state; wherein the second directional control valve further comprises a float state configured to connect at least one of the ascending and descending chambers to the hydraulic reservoir for permitting the boom to move freely in the descending and/or descending directions.

A working machine includes: an operating body switchable between a first position to prevent an operator from getting on/off an operator's seat and a second position to allow the same; a plurality of hydraulic actuators whose operation is enabled when the operating body is in the first position and disabled when in the second position; a manipulation member to be manipulated to operate the hydraulic actuators; and a pattern switching member to be operated switchingly to select one from among a plurality of manipulation patterns of the manipulation member to operate the hydraulic actuators. When the operating body is in the first position, at least a part of the pattern switching member is covered by the operating body so that the pattern switching member is impossible or difficult to be operated. When the operating body is in the second position, the pattern switching member is exposed to be operable.

A cab for a construction machine includes: a specified side wall having a side window frame defining a side window and at least one side transparent plate supported by the side window frame; an air conditioner unit having an air conditioner outlet hole; a side beam extending in a front-rear direction along the specified side wall and below the side window frame; and a side duct located above the side beam, extending in the front-rear direction along a lower section of the side window frame, and receiving at least a part of the air blown out from the air conditioner unit, the side duct having at least one side duct vent for blowing out the air toward the at least one side transparent plate.

An excavator including a lower traveling body; an upper turning body turnably mounted to the lower traveling body; a hydraulic actuator configured to drive a driven part including the lower traveling body and the upper turning body; a hydraulic pump configured to supply hydraulic oil to the hydraulic actuator; a motor configured to drive the hydraulic pump; and a power storage device configured to supply power to the motor. The power storage device is mounted at a right front portion of the upper turning body. The hydraulic pump and the motor are mounted at a rear portion of the upper turning body.
