ABSTRACT:
A multipurpose hand truck has a base frame with a handle frame connected thereto and orientatable to different angular positions relative to the base frame. A pair of wheels, which support the base frame, are mounted for movement in location along the base frame and are releasably securable thereto in at least two alternative spaced apart locations. Preferably wheel support brackets have channel sections therein which are slidable lengthwise along side members of the base frame. Pivotal plates connecting the handle and base frames enable the handle frame to be stored in overlying relation to and spaced above the base frame. A front load retaining plate is invertible to form a rest support.
