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

To provide a cab in which opening and closing of a door is hardly inhibited even if a cab frame or a door is deformed. A cab comprises a cab main body having a cab frame and a doorway formed in the cab frame. The cab comprises a door that opens and closes the doorway of the cab main body. The door is installed to the cab main body so as to be opposed to the side surface of the cab frame in a closed state of the doorway.

To provide a cab coming-off prevention structure of a working machine capable of preventing a coming-off prevention device from falling off. One end side of a stopper shaft portionof a coming-off prevention deviceis inserted through a through-hole. The other end side of the stopper shaft portionis inserted through an insertion hole. A stopper main body portionis provided on the other end of the stopper shaft portion. A portion of the key memberis fitted into a notched portionprovided along a direction crossing an axial direction of one end side the stopper shaft portion. The other part of the key memberprotruding from the stopper shaft portionis fixed to the one of the caband the revolving frame. Even if the key memberis disconnected from the cabor the revolving frame, the coming-off prevention devicecan be prevented from falling off, without the stopper shaft portioncoming off the through-hole, because a portion of the key memberis fitted into the notched portionof the stopper shaft portion

Cab coming-off prevention structure of working machine

A cab in a construction machine, the cab including frame members including a hollow first frame member connected to a second frame member in order to form a corner portion, the first frame member including a pass-through portion formed at a first side surface portion of the first frame member; a reinforcing member that is installed at the corner portion, wherein at least one of two sides of the reinforcing member passes through the pass-through portion and abuts against an inner surface of a second side surface portion of the first frame member that is at an opposite side of the first side surface portion; and a reinforcing plate that abuts against an outer surface of the second side surface portion, wherein the at least one of two sides of the reinforcing member is supported and reinforced by the reinforcing plate.

Reinforcement for cab in construction machine

A vehicle includes a cab; a front window that is capable of moving between a closed position where a window opening at a front surface of the cab is closed and an open position where the front window is housed in a ceiling portion of the cab and the window opening is open; and a guide structure for the front window that guides the front window between the closed position and the open position.
