Moreover, the electric work vehicle includes a battery module positioned within the storage compartment, and a drivetrain including an electric traction motor positioned within the storage compartment and configured to be operated via power supplied from the battery module. The electric traction motor is coupled to a transmission of the drivetrain to allow torque to be transferred from the traction motor to corresponding traction devices of the electric work vehicle.

A swivel working machine includes a swivel base, a prime mover installed in the swivel base, a working device provided at the swivel base, and a support mechanism that supports a fuel cylinder in a rotatable manner around a pivot shaft. The fuel cylinder contains fuel for the prime mover. The support mechanism includes a support rotating body that supports the fuel cylinder and that rotates around the pivot shaft, a rotational-position defining mechanism including a pin that defines a rotational position of the support rotating body around the pivot shaft, and an adjustment mechanism that adjusts a position of the pivot shaft relative to the pin.

A mobile apparatus includes a main frame with displacing means, a rotating sub-frame rotatably connected to the main frame such that the sub-frame is rotatable around a rotation axis relative to the main frame, and a working arm connected to the sub-frame. The sub-frame includes a standing or seating position for an operator. The working arm includes at least two arm segments, and a first arm segment of the at least two arm segments is pivotally connected to the sub-frame around a pivot point located at a distance of the rotation axis. The first arm segment and the sub-frame are configured such that the first arm segment can be moved rearwards onto the sub-frame in the direction of the rotation axis to a rearward position in which the first segment extends over the rotation axis.

The present disclosure provides systems and methods for power machines, including a mini-loader that includes a frame, an operator station positioned toward a rear end of the frame and configured to be used by an operator who is behind or on the rear end of the frame, and a power source positioned toward a front end of the frame.

A shovel includes a lower traveling body, an upper turning body turnably attached to the lower traveling body, a boom pivotably attached to the upper turning body, an arm pivotably attached to the boom, an engine mounted on the upper turning body, a hydraulic pump mounted on the upper turning body, a fuel tank mounted on the upper turning body, a work walkway provided on an upper surface of the fuel tank for the movement of a worker, and a rollover valve provided at the top of the fuel tank at a position different from the work walkway.

A working machine includes a machine body having a front-rear direction and a right-left direction perpendicular to the front-rear direction and having a rear part in the front-rear direction, a right side, and a left side opposite to the right side in the right-left direction. A boom has a front end part and a rear end part opposite to the front end part of the boom in the front-rear direction. The rear end part of the boom is rotatably supported at the rear part of the machine body. The front end part of the boom is to be connected to a working tool. An engine is mounted in the rear part of the machine body. A urea aqueous solution tank is provided on one side of the engine in the right-left direction and a rear side of the engine in the front-rear direction to store a urea aqueous solution.

A machine body comprises a sieving frame having a bottom plate. The machine body comprises an engine. The machine body comprises an exhaust gas cleaning apparatus that executes reduction treatment on a predetermined oxide in an exhaust gas of the engine by injecting a liquid reducing agent. The machine body comprises a reducing agent tank that stores a liquid reducing agent. The machine body comprises a reducing agent pump that feeds the liquid reducing agent stored in the reducing agent tank to the exhaust gas cleaning apparatus. The machine body comprises a cooling fan. The machine body is disposed on the bottom plate of the slowing frame and comprises an opening section that takes in outside air that cools the reducing agent pump by driving the cooling fan. The machine body comprises a duct section that leads the outside air taken from the opening section to the cooling fan.

A diffuser for a return line on a hydraulic tank may include a coupling portion configured for coupling in fluid communication with a return port of the hydraulic tank and for receiving return fluid along an incoming longitudinal direction. The diffuser may also include a dispersion portion in fluid communication with the coupling portion and configured for dispersing the return fluid radially. The diffuser may also include a manifold arranged around the dispersion portion and configured to direct the return fluid circumferentially and axially.

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.

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.
