Abstract: A concrete mixer system includes a washout system and a controller. The washout system includes a tank configured to store a fluid, a plurality of electronically controllable valves in fluid communication with the tank, and a plurality of nozzles. One or more of the plurality of nozzles are fluidly coupled to a respective one of the plurality of electronically controllable valves. Each of the plurality of nozzles is configured to be positioned to facilitate washing a respective component of a concrete mixer vehicle. The controller is configured to (i) receive an indication that the washout system is coupled to a continuous fluid source and (ii) operate the washout system in a continuous wash mode in response to receiving the indication.

Abstract: A washout system for a concrete mixer vehicle includes a plurality of valves, a plurality of nozzles, and a controller. The plurality of valves are configured to (i) be fluidly coupled to a pump and a fluid tank and (ii) receive a fluid from the pump. One or more of the plurality of nozzles are fluidly coupled to a respective one of the plurality of valves. Each of the plurality of nozzles are configured to provide the fluid to a respective target when the respective one of the plurality of valves is selectively activated to an open position. The controller is configured to monitor a plurality of washout parameters during operation of the concrete mixer vehicle and initiate one of a plurality of washout modes in response to a subset of the plurality of washout parameters being satisfied for the one of the plurality of washout modes.

Abstract: A second drive mechanism for a vehicle. The second drive mechanism includes a motor independent of the motor that propels the vehicle. The second drive mechanism may selectively engage the transmission to propel the vehicle in either forward or reverse direction at limited speeds. In addition, the second drive mechanism may include a safety catch configured to ensure the transmission of the vehicle remains in neutral as the mechanism propels the vehicle in forward or reverse direction at limited speeds.
