An engine module for a mixer vehicle includes an engine, a cooling system, and a hood. The cooling system includes a radiator fluidly coupled to the engine and a fan assembly. The fan assembly includes a fan. The hood includes a housing and a door. The housing has a first end configured to be positioned proximate a mixer drum assembly and a second end configured to be positioned proximate a rear end of a chassis of the mixer vehicle. The housing defines an internal cavity within which the engine and the cooling system is disposed. The first end defines an inlet airflow cavity having a bottom surface and an air inlet. The second end defines an opening. The door is pivotally coupled to the second end and positioned to selectively enclose the opening.

A concrete mixer vehicle includes a mixer drum, a chute, and a controller. The mixer drum has an inner volume configured to hold a mixture for transportation and placement. The chute is configured to receive mixture exiting the mixer drum and direct the mixture. The controller is configured to receive a selected mode of operation of the mixer drum and the chute. The selected mode of operation is selected from a set of multiple modes of operation of the mixer drum and the chute. The controller is configured to adjust an operation of at least one of the mixer drum or the chute to cause at least one of the mixer drum or the chute to operate according to the selected mode of operation.

To provide a lighter weight and more robust component for use on a concrete mixer truck, a collector is formed of a non-metallic material which has more desirable characteristics. The collector is further strengthened by providing internal reinforcing structures and reinforced mounting structures so the collector can be effectively coupled to the concrete mixer truck. Additionally, the non-metallic material has desirable characteristics, such as low surface friction levels, high strength to weight ratios, and desirable puncture resistance. All of these characteristics combine to provide a lighter weight, more effective collector.

A chute assembly for directing cement from a cement truck is disclosed. The chute comprises an elongate chute of generally u-shaped cross section fabricated from UHMWPe and comprising an upper end and a lower end, a plurality of reinforcing rods arranged along a length of and encased within the UHMWPe, one end of each of the rods adjacent the upper end and another end of each of the rods adjacent the lower end, a pair of u-shaped collars, an upper one of the collars adjacent the upper end and a lower one of the collars adjacent the lower end, and a fastener for securing each of the collars to their respective rod ends. A method of fabrication is also disclosed.

A drive apparatus for a mobile operating machine, comprising at least one internal combustion motor, an articulated arm to deliver concrete and a pumping unit to pump the concrete from the drum to the articulated arm. The drive apparatus comprises hydraulic pumps configured to pump a working fluid and to determine the drive of the pumping unit and of the articulated arm. The apparatus also comprises at least one electromechanical machine connected to the internal combustion motor, to the hydraulic pumps, and to an electric accumulator.

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.

An apparatus for a lorry-based concrete mixer is described. The apparatus comprises a vessel adapted to be positioned beneath a concrete mixer discharge chute portion, the vessel comprising a vessel body, the vessel body defining a vessel inlet and a vessel outlet, the vessel inlet being adapted to receive debris and fluid exiting the chute discharge portion, and the vessel outlet being adapted to permit debris and fluid stored in the vessel body to be discharged from the vessel body. There is a direct line of sight for a user through the vessel inlet to the vessel outlet.
