Abstract
A four trailer portable concrete batching and mixing plant has production volumes of up to 600 cubic yards of concrete per hour of paving concrete meeting exacting modem paving standards. A first mixer trailer with a mounted water tank forms the plant frame foundation at a twelve-yard compulsory mixer. A second silo trailer having 900 barrel capacity has cantilever support from a steered towing wheel set at the bottom of the silo. The silo trailer is backed at the steered towing wheel set to the side of the compulsory mixer trailer and pinned at its cantilevered connection for pivotal erection. Once pinned to the side of the compulsory mixer trailer, a silo trailer contained jacking system self erects the silo utilizing the compulsory mixer and trailer as a foundation. With the silo erected, a third aggregate trailer occupies the footprint vacated by the erected silo. Fourth, a control trailer having a control booth, power plant and liquid admixture storage is adjustably positioned on the site to complete the plant.
