Abstract
A material handling apparatus may be employed to transfer discrete loads of excavated waste from an excavator or other excavation equipment to a dumping location beyond the reach of the excavator. The material handling apparatus may include a mobile bridge supported by two or more crawlers that enable movement of the mobile bridge. The material handling apparatus may further include a conveyance mechanism that transfers material between first and second ends of the mobile bridge. The conveyance mechanism may transfer material to haul trucks at the second end of the mobile bridge, which may be disposed above the first end of the mobile bridge. The conveyance mechanism may receive material from an intermediate transfer mechanism at the first end of the mobile bridge.
Claims20
A material handling apparatus comprising:
- a mobile bridge including a first end where material is loaded onto the mobile bridge and a second end where material is discharged from the mobile bridge, wherein the second end is distal the first end;
- a conveyance mechanism operatively joined to the mobile bridge and configured to move material between the first and second ends of the mobile bridge, wherein a first part of the conveyance mechanism at the first end where material is loaded is lower than a second part of the conveyance mechanism at the second end where material is discharged;
- an intermediate transfer mechanism configured to receive material from excavation equipment and provide material to the conveyance mechanism;
- and
- crawlers that support the mobile bridge and enable the mobile bridge to be moved, wherein each of the crawlers includes at least one track, with the crawlers being configured to move independently of one another.
A material handling apparatus comprising:
- a mobile bridge including a first end where material is loaded onto the mobile bridge and a second end where material is discharged from the mobile bridge;
- a conveyance mechanism operatively joined to the mobile bridge and configured to move material between the first and second ends of the mobile bridge, wherein a first part of the conveyance mechanism at the first end where material is loaded is lower than a second part of the conveyance mechanism at the second end where material is discharged, wherein the second part of the conveyance mechanism is configured to discharge material into haul trucks;
- an intermediate transfer mechanism configured to receive material from excavation equipment and provide material to the conveyance mechanism;
- and
- means for regulating a manner in which material is discharged from the conveyance mechanism into the haul trucks.
A material handling apparatus comprising:
- a mobile bridge including a first end where material is loaded onto the mobile bridge and a second end where material is discharged from the mobile bridge;
- a conveyance mechanism operatively joined to the mobile bridge and configured to move material between the first and second ends of the mobile bridge, wherein the conveyance mechanism is configured to continuously provide material to haul tracks at the second end of the mobile bridge;
- an intermediate transfer mechanism configured to receive discrete loads of material from excavation equipment and provide material to the conveyance mechanism, wherein the intermediate transfer mechanism controls a rate at which material is provided to the conveyance mechanism;
- and
- means for transferring material in a controlled manner, with at least part of the means for transferring material being disposed above a portion of the conveyance mechanism, wherein the means for transferring material is configured to bring material to rest and prevent transfer of material before selectively transferring material.
