High volume portable concrete batching and mixing plant having compulsory mixer with overlying supported silo

A process of erecting a high volume portable concrete plant on a plant site comprising the steps of:

• providing a first trailer having a transporting wheel set at one end, a point for towing attachment at the other end, and supporting a compulsory mixer between the wheel set and point for towing attachment with one side of the compulsory mixer exposed to a side edge of the first trailer;
• positioning the first trailer on the plant site to support the compulsory mixer on the plant site;
• providing a second trailer having a steering transporting wheel set at one end, a point for towing attachment at the other end, and a cement silo supported in a horizontal transport position between the point for towing attachment and the wheel set;
• providing a cantilever pivot for attachment to the cement silo at one end and pivotal attachment to the second trailer at the steering transporting wheel set to enable the cement silo to pivot from the horizontal transport position to an erect disposition overlying the compulsory mixer;
• positioning the second trailer at the steering transporting wheel set adjacent the compulsory mixer at the one side of the compulsory mixer by backing and steering the steering transporting wheel set;
• pivoting the cement silo relative to the compulsory mixer on the cantilever support from the steering transporting wheel set of second trailer to move the silo from the horizontal transport disposition to the erected position overlying the compulsory mixer, and,
• elevating the compulsory mixer after the pivoting of the cement silo step whereby the compulsory mixer and cement silo are elevated together.

• the first trailer placed on the plant site to support the compulsory mixer on the plant site;
• a second trailer having a transporting wheel set at one end, a point for towing attachment at the other end, and a cement silo supported in a horizontal transport position between the point for towing attachment and the wheel set;
• the cement silo defining a hood for extending over the compulsory mixer, the hood enclosing a manifold for discharging water into the compulsory mixer;
• a cantilever pivot for attachment to the cement silo at one end and pivotal attachment to the first trailer at the other end to enable the cement silo to pivot from the horizontal transport position adjacent the compulsory mixer to an erect disposition overlying the compulsory mixer;
• the cantilever pivot attached between the cement silo and first trailer;
• the cement silo and second trailer overlying and supported relative to the compulsory mixer;
• and,
• means for elevating the compulsory mixer whereby the cement silo is also elevated and a vehicle for receiving concrete can pass under the compulsory mixer for direct discharge from the compulsory mixer of mixed concrete.
