An apparatus (10) for a lorry-based concrete mixer (12) is described. The apparatus (10) comprises a vessel (14) adapted to be positioned beneath a concrete mixer discharge chute portion (16), the vessel (14) comprising a vessel body (18), the vessel body (18) defining a vessel inlet (20) and a vessel outlet (22), the vessel inlet (20) being adapted to receive debris and fluid exiting the chute discharge portion (16), and the vessel outlet (22) being adapted to permit debris and fluid stored in the vessel body (18) to be discharged from the vessel body (18). There is a direct line of sight (24) for a user (26) through the vessel inlet (20) to the vessel outlet (22).

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 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.

An apparatus for a lorry-based concrete mixer comprising a vessel adapted to be positioned beneath a concrete mixer discharge chute portion when the discharge chute is in a stowed position, the vessel being adapted, in use, to receive and retain debris exiting the discharge chute portion while the lorry-based concrete mixer is in motion, the vessel being further adapted to receive wash down water.

The present invention relates to a new method and system for reclaiming and recycling the concrete residue that remains on key components of a concrete mixing truck in a safe and environmentally responsible manner. Any slurry aggregate remaining on the chutes or other parts of the concrete mixing truck is collected by a concrete collection system that is attached to the concrete mixing truck and includes an augur conveyor enclosed in a housing, whereby the augur conveyor is hydraulically extended either behind or in front of the chutes of the concrete mixing truck depending on a type of mixing truck. The augur conveyor can be raised to a maximum height in order to discharge any collected slurry aggregate from the chutes or other parts of the truck back into a top hopper of the concrete truck to be directed back into the mixing drum of the concrete mixing truck.

A method includes the steps of (a) providing a flow of a flowable substance, the flow comprising bulk material and additional material; (b) determining the volume flow of the flow of the flowable substance at one or more detection points X along the flow of the flowable substance; (c) determining a signal caused by the additional material present in the flow of the flowable substance at one or more detection points Y along the flow of the flowable substance, the signal being proportional to the amount of the additional material present in the flow of the flowable substance passing the one or more detection points Y; and (d) converting the signal caused by the additional material present in the flow of the flowable substance into a signal per unit of volume of the flow of the flowable substance.

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.
