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 composite chute for a commercial vehicle includes a metal frame, and a pair of plastic sheets. The metal frame assembly defines a longitudinal axis. The pair of plastic sheets extend along the longitudinal axis and positioned on either side of the metal frame assembly. The metal frame assembly is sandwiched between the pair of plastic sheets.

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 vehicle includes a chassis, a cab, a drum coupled to the chassis and configured to mix a concrete mixture received therein and selectively dispense the concrete mixture, a chute configured to be operable between a raised position and a lowered position such that, when in the lowered position, the chute is configured to receive the concrete mixture from the drum and provide the concrete mixture to a work location, a sensor configured to detect an operational characteristic and provide signals relating to the operational characteristics, and a control system. The control system is configured to receive the signals relating to the operational characteristic from the sensor, determine, based on signals relating to the operational characteristic, when the vehicle entered an operational state, generate a timestamp indicating when the vehicle entered the operational state, provide the timestamp and the operational state to a fleet management system.

A concrete mix separating device for generating cement slurry from a concrete mix includes a bar, which is insertable between adjacent sections of a concrete chute so that a gap is created between the adjacent sections. The bar is sized so that aggregate of a concrete mix, which passes through the concrete chute, is selectively excluded from passing through the gap. Cement slurry, which is substantially free of aggregate, is generated from the concrete mix and passes through the gap. A funnel is attached to the bar so that the funnel is positioned below the gap upon insertion of the bar between the adjacent sections of the concrete chute. The funnel directs the cement slurry into a receptacle, such as a bucket or a wheelbarrow, which is positioned below the funnel.

A system includes a processing circuit configured to receive data from a sensor of a vehicle. The data includes one or more operational characteristics including at least one of a first operational characteristic indicating that a concrete mixture is being dispensed via a chute of the vehicle or a second operational characteristic indicating that the concrete mixture has stopped being dispensed via the chute. The processing circuit is also configured to receive a first time stamp responsive to receiving the first operational characteristic. The processing circuit is also configured to provide the first time stamp to at least one of a user device or a remote computing system.

A concrete mixer vehicle includes a chassis having a front end and a rear end, a cab coupled to the front end of the chassis, a mixer drum assembly supported on the chassis, and a chute storage assembly. The chute storage assembly includes a first chute segment, a second chute segment, and a chute storage rack coupled to a lateral side of the cab. The chute storage rack includes a platform having a first slot configured to receive an end of the first chute segment to support the first chute segment in a storage position. The platform also has a second slot configured to receive an end of the second chute segment to support the second chute segment in the storage position. The first chute segment and the second chute segment are arranged vertically in the storage position.

This specification relates to systems, methods and apparatus for automating and guiding the delivery of concrete from a concrete mixer. According to a first aspect of this specification, there is described a system for positioning a delivery chute (104, 210) of a concrete mixer vehicle (100, 200), the system comprising: one or more vehicle positioning sensors (116) for determining location data specifying a location of the concrete mixer vehicle (100, 200); the delivery chute (104, 210) for delivering the concrete mix from a concrete mixing drum (102) to a target location (204), the delivery chute (104, 210) comprising: one or more chute positioning sensors (112) for monitoring a position of the delivery chute (104, 210); and one or more actuators (110) for positioning the delivery chute (104, 210); one or more processors; and a memory, the memory storing computer readable instructions that, when executed by the one or more processors, cause the system to perform a method positioning a delivery chute (104, 210) of a concrete mixer vehicle (100, 200). The method comprises: determining, based on the location data, whether the concrete mixer vehicle (200) is at a target vehicle location (206); initiating, based at least in part on determining that the concrete mixer vehicle (200) is at the target vehicle location (206), deployment of the delivery chute (210) from the concrete mixing vehicle (200); positioning, based at least in part on data from the one or more chute positioning sensors (112), the delivery chute (210) to a target delivery location (204) using the one or more actuators (110); and indicating, to a user of the concrete mixer vehicle, that the chute is in a correct position for concrete delivery.

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 concrete/cement resurfacing machine integrates a dust collection subsystem and an overlay mixing/distribution subsystem, enabling a single operator to steer the machine to a desired floor location and deposit mixed, cementitious overlay material. The combination of dust collection and overlay mixing saves considerable time and achieves improved results, eliminating the need for separate vacuum machines while reducing the risk that dust will be released as bags of dry ingredients are added to the mixing tank. A single propane engine powers a hydraulic pump, with fluid being routed to three separate hydraulic motors with associated control valves to provide for forward/reverse locomotion, bidirectional paddle mixing, and vacuum generation. The dust collection system is preferably a two-stage system including a vacuum collection tank and a HEPA filter.
