In the figures there is provided a bin handling apparatus comprising a trailer (10) having a pair of spaced chassis members (14) defining a rear-opening space. A hoist assembly (16) includes spaced support beams (17) pivoted at pivots (20). The forward ends of the support beams (17) are interconnected and support a hoist tower (22) having a lift chain moving a tine carriage (24) from which is cantilevered a pair of spaced lifting tines (26). A tipping ram (27) serves to rotate the hoist assembly (16) about the pivots (20). A headstock (30) on the hoist tower (22) has apertured bin engaging lugs. An open-topped bin assembly (31) has a movable wall (35) hinged to the upper, rear edge and forming a closure which can be locked in the closed position by latches. The front wall of the bin has engagement lugs (37) with apertures adapted to align with the apertures in the bin engaging lugs, and be retained by an elongate steel pin (40).
