The mixer of the vehicle is pivotally mounted on the trailer for movement in a vertical plane. Means carried by the trailer and coupled with the mixer thereon raises the same from a lowered, over-the-road position to an elevated, materials-transfer position, whereby concrete can be transferred from the mixer on the trailer to the mixer of the truck. The trailer has a tongue for releasable connection to the rear end of the truck.，下面是Trailer having concrete mixer thereon专利的具体信息内容。

权利要求

1. A concrete hauling unit comprising: a truck having a concrete mixer mounted thereon for rotation about a first inclined axis and provided with an opening near the rear end thereof for permitting concrete to be received therein; a trailer having a concrete mixer mounted thereon and rotatable relative thereto about a second inclined axis, the mixer on the trailer having an opening near the front end thereof for permitting concrete to be removed therefrom and being pivotal relative to the trailer from a lowered, stabilized position to an upper position at which the opening thereof is in alignment with the opening of the mixer of the truck, whereby concrete can be transferred therebetween, means on the trailer for rotating the mixer thereof, and means carried by the trailer for raising and lowering the lastmentioned mixer; and means releasably interconnecting the truck and the trailer.

2. A hauling unit as set forth in claim 1, wherein said interconnecting means includes a tongue movable into a location to permit the rear end of the truck to be moved into proximity with the front end of the trailer when the truck and trailer are not interconnected to permit direct transfer of concrete from the mixer of the trailer to the mixer of the truck.

3. A hauling unit as set forth in claim 1, wherein said trailer has a pin mounted thereon for pivotally mounting the mixer thereof for rotation in a generally vertical plane.

4. A hauling unit as set forth in claim 1, wherein said raising and lowering means includes a fluid piston and cylinder assembly.

5. A concrete carrier comprising: a trailer adapted to be towed over the ground; a concrete mixer including a drum having an outlet opening and a pair of spaced ends; a pair of bearings on respective ends of the drum for mounting the mixer on the trailer for rotation about a generally inclined axis with the outlet opening bearing near the bearing adjacent to the front end of the trailer, the bearing near the rear end of the trailer being below the front bearing and pivotally mounted on the trailer to permit pivotal movement of the drum in a generally vertical plane; means coupled with the mixer for rotating the same about said axis; and means coupled with the trailer and to the front bearing for pivoting the mixer from a lowered position for movement over the road to an elevated position at which concrete can be transferred from said outlet opening thereof.

6. A concrete carrier comprising: a trailer adapted to be towed over the ground, said trailer having a tongue pivotally mounted on the front end thereof for attachment to a concrete mixer truck, said tongue, when disconnected from the trailer, being disposed to permit the truck to move rearwardly and into proximity to the front end of the trailer; a concrete mixer having an outlet opening; means mounting the mixer on the trailer for rotation about a generally inclined axis and for pivotal movement in a generally vertical plane, the outlet opening being near the upper end of the mixer; means coupled with the mixer for rotating the same about said axis; and means coupled with the trailer for pivoting the mixer from a lowered position for movement over the road to an elevated position at which the outlet opening thereof is in alignment with the corresponding opening of the mixer on the truck When the truck is adjacent to the front end of the trailer, whereby concrete can be transferred from the mixer on the trailer to the mixer on the truck.
