A mixer vehicle system includes a mixer vehicle and an autonomous control system. The mixer vehicle includes a chassis and a vehicle body. The vehicle body includes a plurality of subcomponents including a cabin, a mixing drum, a charge hopper, and a chute. The autonomous control system is configured to automate an operation of the mixer vehicle. The autonomous control system includes a sensor and a controller. The sensor is configured to detect an event and generate a signal. The controller is configured to receive the signal and generate an output. The output includes the operation of the mixer vehicle. The operation of the mixer vehicle includes at least one of: (i) moving at least one of the plurality of subcomponents to a desired position; (ii) activating or deactivating at least one mode of operation; and (iii) providing an alert to an operator of the mixer vehicle.

The present invention relates to a control for truck mixers having a hydraulically driven mixer drum, with the hydraulic pump of the mixer drive being driven by the drive motor of the truck mixer or by a separate motor. In accordance with the invention, the speed of the drive motor is adjustable in dependence on the demanded drum speed, with the desired drum speed being able to be set via an operating lever.

A concrete mixer including a mixing tub having an annular side wall and a bottom wall, a main frame configured to rotatably support the mixing tub, where the main frame includes a telescoping member that is capable of extending between a first length and a second length, and a base frame supporting the main frame. The base frame includes a first leg having a first wheel to enable transport of the concrete mixer, and a second leg having a foot to prevent the concrete mixer from rolling away.

A mixing drum includes a body defining a head aperture and a discharge aperture opposite the head aperture, a head coupled to the body and extending across the head aperture, and a mixing element positioned within the volume and coupled to the body. The head and the body define a volume. The body is formed from at least a first section and a second section. The first section overlaps the second section.

A mixing drum includes a body defining a head aperture and a discharge aperture opposite the head aperture, a head coupled to the body and extending across the head aperture, a bearing member coupled to the body and defining a bearing surface surrounding the body, and a mixing element positioned within the volume and coupled to the body. The head and the body define a volume configured to contain a fluid mixture. The mixing element is configured to drive the fluid mixture toward the head when the drum is rotated in a first direction. The mixing element is configured to drive the fluid mixture towards the discharge aperture when the mixing drum is rotated in a second direction opposite the first direction. The head is made from a first material, and the body is made from a second material having a lesser density than the first material.

A mixing drum includes a body defining a discharge aperture, a head coupled to the body opposite the discharge aperture, and a mixing element. The body includes an inner layer defining an interior surface of the body and an outer layer defining an exterior surface of the body. The head includes a connecting flange extending between the inner layer and the outer layer of the body. The head and the body define a volume. The mixing element is positioned within the volume and coupled to the body.

The present disclosure provides for a container having an interchangeable liner. The container is comprised of a bottom portion having an aperture to receive the interchangeable liner as well as securing protrusions and stabilizing members. The securing protrusions serve to cooperate with the aperture to lock the liner within the container, whereas the stabilizing members serve to stabilize the container when a substance within the container is being mixed.

Disclosed is an apparatus and method for manufacturing high-performance concrete by introducing air into normal concrete and dissipating air, wherein high-performance concrete is formed in a manner in which bubbles, which are to be removed, are added in a large amount together with an admixture to pre-blended normal concrete so that the admixture is uniformly dispersed in the normal concrete using the ball-bearing effect of the bubbles, thus forming mixed concrete, and the mixed concrete is discharged using air at a high pressure of 5 atom or more to thereby shoot high-performance concrete of which the slump, remarkably increased due to the large amount of bubbles, is reduced to fall within the range of slump of normal concrete while dissipating excess air from the mixed concrete.
