Early tripper conveyors used canvas belts, but now they're made from more flexible and durable plastics. Each belt is sealed at the ends, roughly 2 feet wide by 16 long. A flap is affixed every 4 feet. Keeping the belts taut are shafts or rollers slipped through either end. They're held off the ground by a more solid metal framework. A cog is attached to the outer end of each roller, and a metal chain, much akin to that found on a bicycle, attaches them. One section of belt attaches by means of yet another cog and chain to the next for as long as needed for the tripper conveyor to serve its purpose in transporting materials. | |||

Although the conveyors move by a repeating series of linkages between rollers, the power source of these linkages is not always the same. Initially, large diesel motors were used. The motor's flywheel would connect to a gear exchange called a speed reducer to give the first roller in the series the low speed and high torque required to move so much weight. However, the chains between cogs would often break under the strain. For that reason, newer model tripper conveyors have a smaller motor attached to the underside of the conveyor for every hundred yards of belt. While this increases consumption of fuel, it lessens time wasted in repairing damaged parts because the conveyor remains functional to some degree. | Although the conveyors move by a repeating series of linkages between rollers, the power source of these linkages is not always the same.
