A vehicle mountable, self-contained independent transit concrete mixer operating system is provided in two pre-assembled modular parts for mounting on a truck chassis. The system needs only power take-off, electrical and control system connections to be operable.

A tailgate lock-open system is provided in the form of a locking system for each tailgate opening cylinder of a rear discharging refuse collection truck body with a top hinged pivoting tailgate and having fluid-operated cylinders connected between the refuse collection body and the tailgate in which extension of the cylinder rods swings open the tailgate. The locking system includes a locking collar that can be advanced to a locking position in which it fits over a portion of a cylinder rod and has a length that determines a minimum rod extension distance. An operating assembly is provided for advancing and withdrawing the locking collar from the corresponding cylinder rod.

A mounting system for mounting a container handling device on a refuse gathering vehicle accomplishes the mounting in a manner which enables translation of the device between deployed and stowed positions so that the container handling device is protected and out of the way when not in use.

Steerable tag axle assemblies include an axle mounting lever carrying a wheel on a stub axle and either a kingpin pivot or a spherical bearing pivot for laterally turning the wheel. The lever pivots between a stowed position and a deployed position where lateral forces from the ground urge the wheel to follow the vehicle. In one embodiment, a kingpin pivot connects the stub axle to the lever and a tie rod maintains alignment of the pair of stub axles. In another embodiment, a kingpin pivot connects the lever to a pivoting shaft attached to the vehicle. The shaft turns as the lever moves between the deployed and stowed positions, and the lever pivots laterally at the kingpin pivot to turn the wheels. In another embodiment, a spherical bearing is carried by a spherical bearing mount securely attached to the vehicle. The bearing engages the lever in a bearing cavity, such that the lever pivots laterally and between the stowed and deployed positions on the bearing. Lateral movement of the wheel is limited in each embodiment.
