Bulk lift and dump system

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

• a first guide rail (103a) and a second guide rail (103b) having lengths sized to span a distance between a first side wall (31a) and a second side wall (31b) of a dump body (31) of a vehicle (20);
• a guide rail cart (104) configured to secure the first guide rail (103a) and the second guide rail (103b) in a spaced apart and parallel relationship;
• a first lift frame post (21Pa) configured to be secured parallel to and proximate the first guide rail (103a) via the guide rail cart (104), and a second lift frame post (21Pb) configured to be secured parallel to and proximate the second guide rail (103b) via the guide rail cart (104);
• a first trolley frame assembly (100a) configured to be secured to a first end of the first guide rail (103a) for translating along the first side wall (31a);
• a second trolley frame assembly (100b) configured to be secured to a first end of the second guide rail (103b) for translating along the first side wall (31a);
• a third trolley frame assembly (100c) configured to be secured to a second end of the first guide rail (103a) for translating along the second side wall (31b);
• and
• a fourth trolley frame assembly (100d) configured to be secured to a second end of the first guide rail (103a) for translating along the second side wall (31b);
• whereby bulk materials loaded within a lift container (29) secured to the first lift frame post (21Pa) and second lift frame post (21Pb) can be lifted by the first lift frame post and second lift frame post by rolling along the first guide rail (103a) and second guide rail (103b) respectively, can be translated laterally along dump body (31) by the trolley frame assemblies (100), and then can be dumped into the dump body.
