Abstract: A hydraulically operated concrete transfer chute having a plurality of telescoping generally U-shaped chute sections which are arranged to telescope together onto a first chute section pivotally connected to a concrete truck, the inner end of the first chute being aligned to receive the concrete discharged from the concrete truck, the first chute section having a planar bearing surface on each of the top sides and inside of the first chute, each of the two parallel planar bearing surfaces extending from the outer end of the first chute at least to the point at which concrete enters the first chute section, and each of the plurality of telescoping chute sections having a plurality of roller bearings aligned in a row along the inside of each of the top sides of each of the telescoping chute sections, each of the rows of roller bearings being covered on their top side by a planar bearing surface.
