A cleaning system is disclosed for cleaning concrete residue from a concrete mixer truck. The cleaning system may include a water delivery system having one or more conduits configured to deliver pressurized water to one or more spray headers positioned at various back-end portions of the truck. The cleaning system further includes one or more valves configured to control the flow of pressurized water through the one or more conduits to the one or more spray headers. In various embodiments, the one or more valves are manually operable to control the release of water to the spray headers. In other embodiments, the one or more valves are controlled by a computing device through an electrical coupling such as a communication bus. The cleaning system may be configured to clean different portions of the truck using different sets of spray headers at different times as part of a washing protocol.

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.

A device for transporting waste includes a generally cylindrical hollow container having a top portion and a bottom portion, the top portion having an outer diameter which is larger than an outer diameter of the bottom portion, wherein the top portion and the bottom portion are of a cylindrical configuration having a common center; and two elongated parallel recesses positioned on the bottom portion, the parallel recesses extending from one side of the bottom portion through the opposite side of the bottom portion and equidistant from the common center, wherein the parallel recesses are adapted to receive forklift arms.

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.

A concrete mixer system includes a non-transitory computer-readable medium. The non-transitory computer-readable medium stores instructions causing one or more processor to perform operations. The operations include receiving an indication that a mixing drum of a concrete mixer vehicle is about to be charged and controlling an electronically controllable valve in response to the indication such that a fluid is provided to a nozzle to facilitate pre-wetting a charge hopper of the concrete mixer vehicle prior to the mixing drum being charged.

A spraying system and method is provided for more efficiently accessing the interior of a container having an access opening to the container that is offset from or in angular relationship to the center and/or rotational axis of the container to contact the interior walls and surfaces of the container with a medium, such as a liquid, mixture, solution or suspension. The spraying system and method includes a non-linear boom that is elevated by a support structure, where the non-linear boom includes at its front end a plurality of spray nozzles. In one example, the support structure is a movable support structure that includes a guide mechanism where the guide mechanism is mounted on the moveable support structure at an angle relative to the surface supporting the moveable support structure to allow access to the interior of the container.

A concrete mixer vehicle includes a chassis, a cab, a mixer drum assembly coupled to the chassis, a ladder assembly, and an assist assembly. The chassis includes a front end and a rear end. The ladder assembly includes an upper ladder portion and a lower ladder portion. The upper ladder portion is fixed in position relative to the chassis. The lower ladder portion is pivotally coupled to the upper ladder portion and selectively repositionable between (a) a stowed position in which the lower ladder portion is disposed along the upper ladder portion and (b) a lowered position in which the lower ladder portion extends away from the upper ladder portion. The assist assembly is coupled to the upper ladder portion and the lower ladder portion. The assist assembly configured to resist the rotation of the lower ladder portion as it transitions from the stowed position to the lowered position.
