Bulk lift and dump system

A detachable loading apparatus configured to be mounted on a cargo container (31) of a vehicle (20) for handling, lifting, and dumping bulk materials (22) comprising:

• a lift assembly (21) adjustably securable to a cargo container (31), the lift assembly comprising:
• a pair of parallel lift tracks (23a, 23b), wherein the lift tracks (23a, 23b) are cane-shaped, comprising a straight portion at a lower end and a curved portion at an upper end, the curved portion curved toward an inside of the cargo container (31) to an extent that bulk materials (22) in the lift container (29) are tipped into the bulk container by gravity when the lift container is in an upper position on the lift tracks;
• rollers (44a, 44b) configured to roll vertically up and down along the lift tracks;
• and
• trolley wheels (59a, 59b) attached to the lift tracks (23a, 23b) on a side opposite of the lift container (29);
• a control enclosure assembly (54) secured to the lift assembly (21), the control enclosure assembly comprising:
• a linear actuator (80);
• and
• a cable and pulley system (75) in operative communication with the linear actuator;
• and
• a lift container (29) attached to the rollers (44a, 44b) and the cable and pulley system (75);
• such that the lift container is configured for being loaded with bulk materials (22) at a lower position on the lift tracks (23a, 23b), raised to a higher position by operation of the control enclosure assembly (54), and tipped to dump the bulk materials into the cargo container (31);
• and
• a trolley frame (58) extending a width of the cargo container (31), the trolley frame comprising:
• a respective collar bracket (56a, 56b) secured with a downward facing opening at each end of the trolley frame;
• a respective set of wheel brackets (33a, 33b) secured within the opening of the collar brackets;
• a set of wheels (34a, 34b, 34c, 34d) secured to the wheel brackets and configured to roll the trolley frame along a length of a top rail (32a, 32b) of the cargo container (31);
• a set of fixed rollers (60a, 60b) fixed to one end of the trolley frame (58) configured to roll the lift tracks (23a, 23b) over the trolley frame,
• whereby the lift assembly (21) is movable from a vertical position on a side of the vehicle (20) for handling the bulk materials (22) to a horizontal position over the cargo container (31) for transportation with the vehicle.
