Abstract
The invention provides a conveyor assembly having a support structure and a first conveyor extending from the support structure. There is a first vertical pivot for permitting rotation of the first conveyor about the support structure in a generally horizontal plane. There is a first horizontal pivot for permitting vertical pivoting of the first conveyor relative to the support structure and a hydraulic cylinder for maintaining the first conveyor at a required vertical angle while cantilevered from the support structure. There is a second conveyor extending from the second end of the first conveyor, and a second vertical pivot for connecting the second conveyor to the second end of the first conveyor and permitting rotation of the second conveyor about the second end of the vertical conveyor in a generally horizontal plane. There is a second horizontal pivot permitting pivoting of the second conveyor in a vertical plane and a hydraulic cylinder for maintaining the second conveyor at a required vertical angle while cantilevered from the second end of the first conveyor. There may also be a third conveyor having a first end for mounting adjacent the ground, and a second end for mount…
