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. The mobile conveyor modules are designed to be steerable and self-propelled, providing increased maneuverability and reducing relocation/reformation time. Multiple stacking methods may be used with the mobile conveyor modules either separately, or at the same time, advance and retreat stacking, the stacking of a berm, or the filling in of a corridor, may be accomplished on a variety of terrain.

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.
