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.

Systems, assemblies, and methods for locking cab to main body of work machine

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.

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.

Traveling machine for power shovels

A travelling frame of a travelling device positioned between a center frame and a travelling motor attachment portion includes an upper plate extended toward the center side of the vehicle to form an extended portion. A long hole into which travelling motor hydraulic piping is inserted is formed in the upper plate along the extended portion. The travelling motor hydraulic piping extends from a lead-out hole opened in an end plate of the center frame, through the long hole of the upper plate and a long hole opened in an end plate, and inserted into the travelling motor attachment portion.
