Abstract
A portable transit mix unit comprising a support base and concrete mixer drum thereon, is provided with rollers movably connected to the base whereby the base can be elevated out of engagement with the bed of a truck or lowered to support the unit directly on the bed. In the elevated position of the base, the unit can be rolled off of the truck bed onto a support stand. This enables the truck to be used for other purposes while the unit is supported on the stand. The stand includes a tiltable platform which when inclined forwardly, facilitates transfer of the unit from the platform onto the truck bed.
Claims10
A transit mix system comprising a portable transit mix unit including a support base having a concrete mixer drum supported thereon, rollers carried by said base enabling the unit to be rolled on the bed of a truck, means movably connecting said rollers to said base for selectively elevating and lowering said unit out of or into engagement with said bed whereby the unit can be rolled on said bed or into engagement with said bed for fixed support thereon, a support stand including a support platform for the unit, and means carried by said stand for detachable connection to said unit to transfer the unit from the bed onto the platform when the unit is in elevated position on the rollers and the bed of the truck is adjacent the front of the platform.
The method of rendering a truck useful for other loads in a transit mix system wherein a portable transit mix unit is mounted on the bed of a truck, which comprises providing support rollers on the unit enabling it to be moved readily, movably connecting said rollers to said unit for selectively elevating and lowering said unit out of or into fixed engagement with said truck bed, providing a support having a support platform for said unit, backing the truck adjacent the front of the platform, with the unit elevated relative to said bed, rolling the unit from the truck bed onto the platform, and when such unit is to be used again on the truck rolling it from the platform onto the truck bed, and subsequently lowering said unit into fixed engagement with said truck bed.
The method of rendering a truck useful for other loads in a transit mix system wherein a portable transit mix unit is mounted on the bed of a truck, which comprises providing support rollers on the unit enabling it to be moved readily, providing a support having a support platform for said unit, backing the truck adjacent the front of the platform, rolling the unit from the truck bed into the platform, and when such unit is to be used again on the truck rolling it from the platform onto the truck bed;
- said method further comprising providing a winch and a cable which is carried by the support to roll the unit from the truck bed, and the unit is rolled under gravity from the platform by providing a tiltable mount for the platform, allowing the platform to tilt forwardly under the weight of the unit, and controlling the rolling under gravity by the winch.
In a transit mix system, a truck for transporting a portable unit having a base and a concrete mixer drum mounted thereon, said truck having a bed comprising spaced apart flat horizontally extending side plates positioned at substantially the same level and a well therebetween to receive the unit for lowering the center of gravity when the unit is supported on the truck, and a cover plate for removable mounting over said well substantially even with said side plates to provide a flat truck bed when desired which extends substantially full width of the truck.
