ABSTRACT:
Transport and erection of a portable asphalt plant are facilitated by transporting upper and lower subassemblies of the plant to a worksite on a single portable frame towed by a tractor. Once at the worksite, the frame is detached from the tractor and the upper plant subassembly is moved on the frame from a lowered transport position generally beside the lower plant subassembly to an intermediate position directly above the lower plant subassembly. The plant assembly is then completed by attaching the upper plant subassembly to the lower plant subassembly and raising the lower and upper plant subassemblies as a unit to a raised position which is sufficiently high to permit trucks to pass beneath the lower plant subassembly. An elevator is preferably transported to the worksite via another vehicle, then mounted on a pivot axis of the frame, and then pivoted about the pivot axis from a horizontal transport position to an upright operative position.
