Abstract

A self-erecting silo assembly comprises a horizontally elongated trailer frame and a cylindrical paving mix bin that overlies the frame when in a horizontal transport position, with its front side lowermost and its top end near a front end of the frame. Rear legs on which the bin is supported when erected are rigidly connected to the bin; front legs have their upper ends pivoted to the bottom of the bin. A detachable bin connection between the bin and the frame defines a horizontal axis about which the bin is swung up from transport position to an inclined intermediate position at which detachable leg connections are made between the rear legs and the frame. The bin connection is then disconnected, the bin is swung up to upright position about the leg connections, and the bottom ends of the front legs are connected to the frame. Jack cylinders having upper ends connected to the bin have lower ends connected to the frame at a forward location for raising the bin to intermediate position and at a more rearward location for raising the bin to upright position. A slat conveyor elevator comprising a separate trailer has its front end hoisted to the top of the erected bin by cables extending from a winch on the front of the bin frame, across the top of the bin, and to the front of the elevator unit, which is guided during hoisting by rollers on it, engaged in a track extending up the rear side of the bin.
