An anti-collision system includes a truck cab defining a truck cab volume and a sensor positioned with respect to the truck cab. The truck cab is rotatable with respect to the truck chassis along a rotation path to define a truck cab rotation volume. The truck cab volume is entirely within the truck cab rotation volume along the entire rotation path, i.e., the truck cab rotation volume encompasses the truck cab volume at every position of the truck cab volume along the rotation path. The sensor has a field of view (FOV) that overlaps a portion of the truck cab rotation volume to detect an obstruction in the FOV that is within the truck cab rotation volume. The sensor may also cause the system to provide an alert or control rotation of the truck cab in response to detecting the obstruction.

A frame assembly for a vehicle includes a frame having a first end and an opposing second end. The frame has a first frame rail defining a first channel and a second frame rail defining a second channel. The second frame rail is spaced from the first frame rail. The frame assembly further includes a cross member assembly coupled to the first end of the frame and extending between the first frame rail and the second frame rail. The cross member assembly has a first end plate positioned within, and releasably received by, the first channel of the first frame rail; a second end plate positioned within, and releasably received by, the second channel of the second frame rail; and a cross member extending between the first end plate and the second end plate.

A floor mat arranged in a working machine includes a floor portion, a wall portion arranged on a circumferential portion of the floor portion, and an opening portion arranged on a part of a connecting portion of the wall portion, the connecting portion connecting to the floor portion. The floor mat includes a mat main body arranged on the floor portion, a covering portion configured to cover the opening portion, and an connecting portion configured to connect the covering portion flexibly to a circumferential portion of the mat main body.

An air spring includes a closing member, a rolling piston, and an air spring bellows connected to the rolling piston and the closing member to form a fluid-filled pressure chamber. A level control system for supplying and/or discharging fluid may be integrated into the pressure chamber to control level position based on air spring stroke. The level control system may have a control valve and an actuator connected to the control valve. The actuator may include a guide tube coupled to the rolling piston or closing member, and movably arranged within the pressure chamber. An actuating member may include a pin member and may operate the control valve. A compression spring may have a central spring and a biasing spring, and the guide tube may include a control flange coupled to the pin member, and the biasing spring may be supported to press the pin member against the control valve.

A transforming top drive vehicle having a passenger compartment and a separable base is disclosed. One or more hydraulic cylinders are positioned between the compartment and the base to provide force sufficient to raise the compartment. Concentric pipes having sufficient strength to support the compartment are installed with one end connected to the vehicle's base and the other connected to the passenger compartment. The vehicle allows ease of access and the ability to lower the vehicle's center of gravity when navigating rough or uneven terrain and, when the operator is interested in obtaining a better view of wildlife or otherwise increase the field of vision, the passenger compartment can be raised either incrementally or to its fully raised position.

A protection system for a work vehicle includes a rear portion configured to couple to a chassis of the work vehicle and a top portion configured to couple to a cab of the work vehicle. The top portion is also configured so that at least part of the top portion is positioned above the cab of the work vehicle relative to a ground surface. In addition, a first height of a maximum vertical extent of the top portion relative to the ground surface is substantially equal to a second height of a maximum vertical extent of the rear portion relative to the ground surface. Further, the rear portion and the top portion are separated from one another while the rear portion is coupled to the chassis and the top portion is coupled to the cab.
