A working machine includes a ground engaging structure, and an undercarriage supported on the ground engaging structure. The undercarriage has a drive arrangement for moving the ground engaging structure to propel the working machine, the drive arrangement comprising a prime mover and a transmission comprising a hydraulic pump arrangement configured to be driven by the prime mover. A superstructure rotatably mounted to the undercarriage and a working arm is connected to the superstructure. A first implement mount connected the undercarriage for operably mounting a working implement to the undercarriage. The undercarriage has a first actuator for raising and lowering a working implement when mounted to the first implement mount and comprises a hydraulic connector for supplying hydraulic fluid to the first actuator to actuate the first actuator, and a first auxiliary hydraulic connector is provided that is configured for supplying hydraulic fluid to an implement connected thereto.

A machine is adapted for operation powered by any one of a plurality of interchangeable power sources. The machine may include an undercarriage configured for supporting ground engagement members that propel the machine and an upper structure rotatably supported on the undercarriage. The upper structure may include a swing frame, with the swing frame supporting an operator cab, any one of the plurality of interchangeable power sources, hydraulic components, electrical components, and a counterweight disposed at a first end of the swing frame. The counterweight may include a hollowed out portion facing toward the swing frame. The hollowed out portion of the counterweight may be centrally aligned with a center core portion of the swing frame configured for supporting any one of the plurality of interchangeable power sources, with the one power source being partially accommodated within the hollowed out portion of the counterweight.

An energy-saving excavator includes a slideway, a counterweight iron, a first pulley, a main arm, a main arm axle pin, a support, a parabolic-shaped tower groove, a second pulley and a transmission rope; the counterweight iron is slidably connected to a body of the excavator through the slideway, the first pulley is mounted on an upper end of the slideway, the main arm is fixed to the parabolic-shaped tower groove and is rotatably connected to the body of the excavator through the main arm axle pin, one end of the transmission rope is fixed to the counterweight iron, the transmission rope goes around the first pulley and in turn the second pulley, another end is connected to the parabolic-shaped tower groove, and the first pulley is connected to the axle pin of the main arm through the support.

A cover mounting bracket (16) is provided on an upper side of a left weight part (11) and a right weight part (12) constituting a counterweight (10). The cover mounting bracket (16) is formed as a U-shaped frame with the counterweight (10) side open by a left extending member (17) extending forward from the upper side of the left weight part (11), a right extending member (18) extending forward from the upper side of the right weight part (12), and a connecting member (19) connecting the front side of the left extending member (17) and the front side of the right extending member (18). A prime mover cover (28) is supported on the connecting member (19) of the cover mounting bracket (16) rotatably in a vertical direction through a hinge (31). The prime mover cover (28) is moved between an open position where an inspection opening (15) of the counterweight (10) is opened and a closed position where the inspection opening (15) is closed around the hinge (31).

The present disclosure relates to a hydrogen powered working vehicle. Advantageously, the hydrogen-powered working vehicle of the present disclosure is designed to enable existing chassis designs for diesel-powered working vehicles to be re-purposed for use in hydrogen powered working vehicles while still affording adequate lateral airflow and protection to components of the hydrogen powered working vehicle.

A construction vehicle includes a frame and a linkage assembly. The linkage assembly includes a linkage member and a work implement. The work implement includes a wall structure defining a first edge, a second edge, and a material engaging portion. The work implement also includes a first support plate disposed proximate to the first edge. The first support plate defines a first opening proximate to the material engaging portion. The work implement further includes a second support plate disposed. The second support plate defines a second opening proximate to the material engaging portion. The work implement includes a conduit coupled to the first support plate and the second support plate and defining a cavity. Each of the first and second openings are aligned with the cavity. Further, the work implement also includes a weight member removably received within the cavity defined by the conduit.
