Abstract
A trolley configured for use to carry folding tables of a variety of sizes. The trolley includes a loading end, a trolley frame, and an extension gate adjustably connected to the trolley frame so as to be adjustable relative to the loading end of the trolley in a length direction of the trolley. The extension gate includes an elongate member slidingly disposed on the trolley frame and a rotatable portion that is foldable relative to the elongate member and lockable in an upright position by a lock. The rotatable portion may be positioned in an extended position from the loading end of the trolley, in a retracted position adjacent the loading end of the trolley, and in positions that are intermediate to the extended position and the retracted position. The elongate member may slide in a first direction to extend the rotatable portion away from the loading end of the trolley and in a second direction to retract the rotatable portion toward the loading end of the trolley.
