Abstract: Mobile conveyor modules are used for transporting aggregate over a long distance, or for transferring the aggregate to other modules, and for stacking the aggregate either linearly or radially. These modules may be used in various combinations by themselves or in combination with existing conveyor systems and bridge stackers to stack aggregate on and off multi-lift leach pads and on multi-lift dump sites. Multiple stacking methods may be used with mobile conveyor modules either separately, or at the same time, advance and retreat stacking, the stacking of a berm, or the filling in or a corridor, may be accomplished on a variety of terrain.

These modules may be used in various combinations by themselves or in combination with existing conveyor systems and bridge stackers to stack aggregate on and off multi-lift leach pads and on multi-lift dump sites. The mobile conveyor modules are designed to be steerable and self-propelled, providing increased maneuverability and reducing relocation/reformation time.

Abstract: A tripper/hopper car rides on a conveyor via four wheel tires running on T-section rails, with respective hold down wheels riding adjacent the underside of the rails and respective caster side wheels riding adjacent the vertical edges of the T-rails. Each wheel tire is driven by a motor drive unit employing a shaft-mount gearbox with a motor brake that utilizes the reduction of the drive gearbox to increase the effective braking torque developed. A pair of caliper-type brakes is further provided for redundancy.

Abstract: A method for forming a plurality of cells of material wherein a relocatable conveyor is located in front of an area in which the plurality cells are to be formed, and a portable conveyor system is disposed to transfer material from the relocatable conveyor to a material stacker. The portable conveyor system and material stacker are thereafter moved with respect to the relocatable conveyor in order to form a second of the plurality of material cells. A number of the portable conveyors of the portable conveyor system are then used to form the last of the plurality of material cells, while at the same time the relocatable conveyor system is being disassembled and moved to a second area wherein one or more additional cells of material are to be formed. In this manner, significant system down time conventionally experienced in moving a conventional shiftable conveyor is avoided.
