A dump system (9) for loading and discharging bulk material (25G), the dump system comprising:
- a lift frame assembly (6) and a base frame assembly (10);
- the lift frame assembly (6) comprising:
- a container (23, 44), the container comprising:
- a gate opening (91) on a vertical side of the container;
- a gate (24) rotatably attached to the container by
- a gate hinge (67a, 67b) secured proximate to a lower end of the gate opening (91);
- and
- axle brackets (19a, 19b) secured on vertical sides of the container (23, 44) proximate the gate (24);
- a dump frame (11), the dump frame comprising:
- a frame floor (11F), the container (23, 44) disposed on the frame floor (11F);
- and
- a guide pulley (18a, 18b) secured to the dump frame (11) between a middle of the container (23, 44) and an end opposite the gate (24);
- a fixed pulley (70c) secured to the dump frame (11) between the middle of the container (23, 44) and an end closest to the gate (24);
- and
- axle stubs (20a, 20b) secured to the end of the dump frame (11) closest to the gate (24);
- a gate cable (73) secured at one end to the gate (24) capable of lifting the gate loaded with bulk material (25G) and closing the gate to transport the bulk material into the container;
- a gate hydraulic cylinder (71), the gate cable (73) in operative communication with the gate hydraulic cylinder (71), such that the gate (24) is opened and closed by operation of the gate hydraulic cylinder (71);
- a primary lift hydraulic platform cylinder (64);
- and
- a front lift hydraulic cylinder (76);
- the base frame assembly (10) comprising:
- a left base frame (10a);
- a right base frame (10b);
- four base legs (12a-12d) secured to and supporting the left base frame (10a) and right base frame (10b) and defining a storage area (26) between the base legs;
- axle brackets (19Xa, 19Xb) vertically secured to two of the four base legs (12b, 12c) that are closest to the gate (24), the axle brackets comprising channels sized to receive the axle stubs (20a, 20b) such that they can slide up and down vertically within the channels;
- a pulley support (16) secured above the left base frame (10a) and right base frame (10b) at a proximal end of the pulley support;
- a turnbuckle (75a) secured to the pulley support (16);
- a post pulley (17) secured at a distal end of the pulley support (16);
- a cable anchor (3a, 3b) secured to the left base frame (10a) and right base frame (10b);
- and
- a vertical lift cable anchor (79a, 79b) secured to the left base frame (10a) and right base frame (10b);
- a lift cable (7) secured at an end to the cable anchor (3a, 3b), routed through the guide pulley (18a, 18b) and in operative communication with the primary lift hydraulic platform cylinder (64) such that the lift frame assembly (6) can be raised, lowered, and angled by operation of the primary lift hydraulic platform cylinder (64);
- and
- a front lift cable (80) secured at an end to the vertical lift cable anchor (79a, 79b) and in operative communication with the front lift hydraulic cylinder (76) such that an end of the lift frame assembly (6) nearest the gate (24) can be raised and lowered by operation of the front lift hydraulic cylinder.
