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

A work machine comprising:

• a cab riser including 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 support member to support the cab in the first position and a first plate which is connected to the support member in a horizontal direction;
• a main body including a clamping assembly, the clamping assembly including a second plate and a clamping structure, the second plate being mounted on the main body at a predetermined height and arranged to be in parallel with the first plate in a vertical direction when the cab is in the first position, the clamping structure being movable only linearly in a first direction and a second direction opposite the first direction;
• and
• a shaft that rotatably connects the cab riser to the main body, the cab riser being rotatable about the shaft in a clockwise direction and a counterclockwise direction to and from the first position and the second position,
• wherein the first plate of the cab riser and the second plate of the main body are clamped together by the clamping structure in a case where the cab is in the first position, by directly engaging a lower surface of the first plate with an upper surface of the second plate or indirectly engaging the lower surface of the first plate with the upper surface of the second plate by sandwiching another plate between the first plate and the second plate.

A method regarding a forestry work machine, comprising:

• providing a main body;
• providing a cab riser including a cab and a frame, the cab being uprightly positioned on the forestry 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 a case where the cab is in the first position;
• providing a shaft that rotatably connects the cab riser to the main body, the cab riser being rotatable about the shaft in a clockwise direction and a counterclockwise direction to and from the first position and the second position;
• and
• clamping the first plate and the second plate together by a clamping assembly in the case where the cab is in the first position, the clamping assembly being mounted on the main body and including one or more C-shaped clamps to clamp the first plate to the second.
