A concrete mixer vehicle includes a controller that is configured to detect that an engine is in an idle condition and selectively shutdown the engine in response to detecting that one or more override conditions are met.

A concrete mixer vehicle includes a trainer cab that is coupled to a chassis and arranged laterally outwardly relative to a main cab. The trainer cab includes: (a) a seat mounted to a recessed mounting floor that is arranged rearward of a wheel well, (b) a support beam that includes an air vent and air flow path integrated into the support beam, or (c) a windshield wiper with a park location that is arranged between a trainer cab column and a superstructure support so that the windshield wiper is hidden from being viewed from within the main cab.

A mixer vehicle provided with a mixer drum mounted on a vehicle, the mixer drum being adapted to load uncured concrete includes a driving device for rotating the mixer drum and a loaded state detector for detecting whether the uncured concrete is loaded on the mixer drum or not. Rotation of the mixer drum by the driving device is stopped if the vehicle is in the stop state and the loaded state detector detects that the uncured concrete is not loaded on the mixer drum.

An electrified vehicle include a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, an electric motor supported by the chassis, and a trailer coupled to a rear end of the chassis and configured to be towed by the electrified vehicle. The electric motor is configured to drive at least one of the front axle, the rear axle, or a component of the electrified vehicle. The trailer includes a trailer frame, a trailer axle coupled to the trailer frame, and an energy storage device supported by the trailer frame. The energy storage device includes a plurality of batteries. The energy storage device configured to power the electric motor.

A concrete mixer vehicle includes a mixer drum, an additive admixture system, and a controller. The additive admixture system includes an air inlet valve, a fluid valve, an air valve, and a pump. The controller is configured to operate the additive admixture system to transition the additive admixture system between an additive addition mode, a drain mode, and a system clear mode. The controller transitions the additive admixture system into the additive addition mode and operates the pump until a desired amount of an additive is added to the mixer drum, transitions the additive admixture system into the drain mode for a predetermined amount of time in response to the desired amount of additive being added to the mixer drum, and transitions the additive admixture system into the system clear mode for a predetermined amount of time to clear stagnant fluid or built up mixture from the additive admixture system.

A vehicle includes a chassis including a frame rail extending longitudinally, a tractive element coupled to the chassis, an electric motor coupled to the chassis, a shaft coupling the electric motor to the tractive element such that the electric motor is configured to drive the tractive element to propel the vehicle, the shaft extending longitudinally, and a water pump configured to provide a flow of water in response to receiving mechanical energy provided by the electric motor.

A concrete transport vehicle has a vehicle chassis, a concrete drum unit and a drum lift apparatus. The vehicle chassis carries the concrete drum unit and the drum lift apparatus. The concrete drum unit has a concrete drum, wherein the concrete drum is adapted to discharge concrete. The drum lift apparatus is adapted to lift the concrete drum unit with reference to the vehicle chassis from a transport position to a discharge position, wherein a vehicle height of the concrete transport vehicle is lowered in the transport position compared to the discharge position and wherein a drumrear and a drumfront of the concrete drum unit each is lifted in the discharge position compared to the transport position.

An electrified vehicle includes a chassis, a front axle, a rear axle, a vehicle component including at least one of a pump, a compressor, or an alternator, an energy storage device including a plurality of batteries, and an electromagnetic device coupled to both (a) at least one of the front axle or the rear axle and (b) the vehicle component. The electromagnetic device is powered by the energy storage device and configured to selectively provide a mechanical output to (i) the at least one of the front axle or the rear axle and (ii) the vehicle component.

A concrete mixing system includes a vehicle, a rotatable mixing drum coupled to the vehicle, an incline and/or slump sensor, and a controller. The controller is configured to effect a change of rotational speed of the rotatable mixing drum in response to a signal from at least one of the sensors indicating an increased likelihood of spillage of concrete from the rotatable mixing drum.

A concrete mixer vehicle includes a mixer drum, an additive admixture system, and a controller. The additive admixture system includes an air inlet valve, a fluid valve, an air valve, and a pump. The controller is configured to operate the additive admixture system to transition the additive admixture system between an additive addition mode, a drain mode, and a system clear mode. The controller transitions the additive admixture system into the additive addition mode and operates the pump until a desired amount of an additive is added to the mixer drum, transitions the additive admixture system into the drain mode for a predetermined amount of time in response to the desired amount of additive being added to the mixer drum, and transitions the additive admixture system into the system clear mode for a predetermined amount of time to clear stagnant fluid or built up mixture from the additive admixture system.
