A liquid pumping vehicle has: a frame; a platform rotatably mounted on the frame; an articulated boom mounted on the platform; a liquid pump mounted on the boom; and, an engine mounted on the platform, so that a rotation axis of the platform is between the boom and the engine and so that a first turning moment created on a first moment arm relative to the rotation axis by weight of the engine and other components on an engine-side of the platform is balanced under operational conditions of the pumping vehicle by a second turning moment created on a second moment arm relative to the rotation axis by weight of the boom and other components on a boom-side of the platform. The vehicle is better balanced for greater stability when in use for pumping a liquid, e.g., liquid manure.

A universal, mobile, backhoe system integrated with a vehicle and related methods are disclosed. An example embodiment includes: a boom; an arm coupled to the boom; an implement coupled to the arm; a swing mount coupled to the boom, the swing mount including a pivot point; a truck mount removably coupled to the swing mount; stabilizer legs coupled to the truck mount, the truck mount further including a mounting bracket removably coupled thereto and configured to be removably attached to a hitch receiver of a vehicle, the truck mount further including mounting shafts removably coupled thereto and configured to be removably attached to at least two points of a bed of the truck.

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.

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 pressure medium cylinder (1) for moving a toothed bar (3), comprising a toothed bar (3) on at least one side of which is formed a toothing (4). Inside the toothed bar (3), a cavity (6, 6a, 6b) is formed, extending to at least one end (7a, 7b) of the toothed bar. The pressure medium cylinder (1) further comprises a longitudinal structure (8, 8a, 8b), the longitudinal structure (8, 8a, 8b) and the toothed bar (3) being adapted movably in relation to each other, and the longitudinal structure (8, 8a, 8b) is adapted at least partly inside said cavity (6, 6a, 6b). The toothed bar (3) and longitudinal structure (8, 8a, 8b) are adapted in a sealed manner in relation to each other so that the toothed bar and the longitudinal structure are movable in relation to each other by the effect of a pressure medium.

A cushioned swing circuit provides the reduction of oscillation common in the operation of heavy equipment such as with boom members. The circuit utilizes a transfer of high pressure fluid flow (caused by the inertial of the swing during rapid deceleration) from one leg of the circuit to the other leg of the circuit or to the sump which serves as decompression for the oil that would ordinarily be trapped in the leg. These phenomena create the swing cushioning effect.

A working machine includes a cooling fan, and a first cooling device and a second cooling device that are disposed in series in a flow passage of cooling air that is generated by the cooling fan. The first cooling device is disposed upstream of the second cooling device in a direction of flow of the cooling air, and has a heat-exchange suppressing portion that is provided at a portion corresponding to a region in a rotation center vicinity of the cooling fan and that suppresses heat exchange between the cooling air and a fluid that flows in the first cooling device.

A position detection device for detecting the position of a bucket of an excavator having a cab and one or more booms is disclosed. A boom is rotatably attached to the cab by a mounting structure that is rotatably attached to the cab by a shaft having a longitudinal axis extending basically vertically during normal use of the excavator. The bucket is rotatably mounted to a stick that is rotatably attached to the boom. The mounting structure is arranged and configured to allow the boom to be rotated with respect to the longitudinal axis of the shaft. The position detection device comprises one or more antennas arranged and configured to receive satellite signals. The position detection device comprises a sensor assembly configured to detect the angular position of the boom with respect to rotation about the longitudinal axis of the shaft.

A working machine includes a machine body, a traveling device travelably supporting the machine body, a hydraulic driving device to hydraulically drive the traveling device, a floor frame supported on the machine body via a mounting member, a pedal operable to brake the traveling device, the inching valve to change a flow rate of hydraulic fluid supplied to the hydraulic driving device according to operation of the pedal, and a cable operably connecting the pedal to the inching valve. The pedal and the inching valve are attached to the floor frame.

A method may include receiving, from a position sensor associated with a machine, data indicative of a horizontal rotation angle of a boom of the machine. The position sensor may be fixedly mounted to a boom link of the machine and may be fixedly connected through one or more links to the boom. The method may further include sending, to a boom actuator, one or more commands to modify a horizontal position of the boom to a target horizontal position or to a default horizontal position. The target horizontal position may include a position of the boom prior to drift in the horizontal position during operation of linkage elements of the machine and the default horizontal position may include a position of the boom to which the boom is to return after use.
