A walking mud handling system may include a walking mud tank and a plurality of hydraulic walkers coupled to the walking mud tank. Each hydraulic walker may include a walking foot, a hydraulic lift, and a sliding actuator. The hydraulic lift may include a hydraulic cylinder coupled to the walking foot such that extension of the hydraulic cylinder extends the walking foot into contact with the ground. The sliding actuator may include one or more hydraulic cylinders coupled to the walking foot such that extension of the sliding actuator moves the walking foot laterally relative to the hydraulic lift.

Embodiments of safety trucks incorporate multiple connection points to which a variety of attachments, or combinations of attachments, can be releasably and interchangeably coupled to enable their use with increased effectiveness to safeguard roadway construction, maintenance and repair personnel as they perform tasks within or relatively near to roadway workzones and worksites. Also, methods of operation of the safety truck embodiments enhance their ability to guard and protect roadway construction, maintenance and repair personnel while they work within or relatively near to roadway workzone and worksite locations.

A stair assembly for a vehicle includes a frame, a first stair, a second stair, and an actuator. The frame includes a plate extending between a first side member and a second side member. The first stair is rotatably coupled to the frame and includes a first step body positioned on a first side of the plate. The second stair is rotatably coupled to the frame and includes a second step body positioned on the first side of the plate. The actuator is configured to move the first stair and the second stair between a deployed position and a storage position, and the actuator is separated from the first step body and the second step body by the plate.
