Abstract: 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.

Abstract: A work machine comprises a main body, a cab riser, and a shaft. The cab riser includes a cab and a frame, the cab being uprightly positioned on the work machine in a first position, and being tilted forward in a second position, and the frame comprising a first plate to contact a second plate provided on the main body in the first position. The cab riser is rotatable about the shaft in clockwise and counterclockwise directions to and from the first position and the second position. The first plate and the second plate can be clamped together by a clamping assembly in the first position, the clamping assembly including one or more clamps to clamp the first plate and the second plate, and the clamping assembly is mounted on the main body.

Abstract: A work machine comprising a main body and a cab riser. The cab riser includes a cab and a frame comprising a first plate to contact a second plate provided on the main body in a first position which the cab is uprightly positioned on the work machine. The first and the second plate are coupled together to sandwich a key plate in the first position, the key plate being disposed in a space created by a first recess on a lower surface of the first plate and a second recess on an upper surface of the second plate, the second recess being aligned with the first recess vertically in the first position, and the key plate includes a first contact surface as a slope surface and a top surface being adjacent to the slope surface in the cross sectional view of the key plate.

Abstract: To provide a work machine in which a filter can be manufactured at low costs and can be fitted into various shapes. A work machine comprises a cover member configured to partition a machine room in which at least a part of a cooling core is housed. The work machine comprises an opening part formed in the cover member, and configured to take-in an air for cooling the cooling core into the machine room. The work machine comprises a plain-woven wire mesh welded and attached to a position from the opening part to the cooling core, and configured to form a filter that prevents inclusion of dust into the machine room from the opening part.

Abstract: To provide a pipe member being able to reduce the vibration applied and improve its durability. A pipe member to be installed on the body of a construction machine has an outer main pipe and an inner auxiliary pipe inserted into the outer main pipe. An outer diameter of the inner auxiliary pipe is formed smaller than an inner diameter of the outer main pipe. The inner auxiliary pipe has a securing part secured on the outer main pipe and at least one of end parts of the inner auxiliary pipe is a free end without being secured on the outer main pipe.

Abstract: To provide a construction machine capable of preventing damages of batteries placed on a machine-body frame. A construction machine comprises a machine-body frame, a supporting plate installed on the machine-body frame via elastic mounts, and batteries fixed to a topside of the supporting plate. Welding is not performed on the supporting plate.

Abstract: PROBLEM: To provide a toolbox of a working machine capable of storing a long object. SOLUTION: A toolbox has a plurality of storage sections each having an opening that permits access to an interior, and successively adjacently arranged. The toolbox comprises a storage space section that makes any ones of a plurality of interiors adjoining one another of the plurality of storage sections communicate with one another, and permits access from an access opening different from each opening.

Abstract: A first hood member is fixed to an upper side opening edge of machine room and a second hood member is adjacently fixed to the upper side opening edge. The first hood member includes a reinforcing deformation part disposed along one notch-like edge portion positioned above a part adjacent to second hood member and has a protruded-shape cross section upward; and a pressing portion disposed at one notch-like edge portion along the reinforcing deformation part and protruding downward. The second hood member includes a pressed groove portion disposed corresponding to the pressing portion and has a recessed-shape cross section upward.

Abstract: A rubber stopper is formed with a body part having an attach surface part to attach a cover body, a mounting leg part to put into a mounting part hole formed on the mounting part penetratingly and a recessed portion for tucking formed on the attach surface part positioned aligned with the mounting leg part in the front back direction, and the rubber stopper is mounted to the mounting part by putting the mounting leg part to the mounting part hole.
