VMI is proud to announce the introduction of its new self-propelled horizontal dredge; the MD-822-SP. The MD-822-SP uses a unique patent-pending auger drive system to maneuver and position the dredge during operation.

The auger drive system is mounted directly behind the horizontal cutter head to provide thrust and steer the dredge while digging. By placing the auger drive system directly behind the cutter head it allows a better transfer of force to the point of resistance than placing the drives further away. The cutter head can require a significant amount of force to be applied while digging into tough material. The amount of force applied can have a significant impact on the dredge production rate depending on the material and conditions. By placing the drives directly behind the cutter head it limits the distance the two opposing forces have against one another and also enables the dredge to steer better while digging.
