Abstract

A portable self-erecting surge storage silo comprises a bin, a conveyor elevator and a base frame that supports the bin and elevator in operation and for transport. The bin has a pair of long rear legs and a pair of shorter front stub legs. At each side of the base frame is an L-shaped unit having a longer leg and a shorter leg, swingable about a horizontal first axis transverse to the base frame and through the junction of the legs of the L-unit. The shorter legs of the L-units are rigidly connected to the bin stub legs, substantially in alignment with them, for swinging of the bin between a horizontal transport position and an inclined intermediate position at which the rear bin legs are detachably connectable to the base frame for swinging of the bin about a second axis, parallel to the first. The shorter legs of the L-units are disconnected from the stub legs at the intermediate position, and the bin is swung up about the second axis to its upright erected position at which the longer legs of the L-units are connected to the stub legs to cooperate with the rear legs in supporting the bin. The bin is raised by means of a connection with the elevator, which is swung up by hydraulic jacks.
