The RM 802 is a High-Production Ballast Undercutting/Cleaning Machine especially designed to work on track with pre-dumped ballast.

• The Ballast Pick-up Unit picks up the pre-dumped ballast and moves it onto conveyor belts.
• A transition conveyor belt fills the first of several MFS type Ballast Conveyor/Hopper Cars.
• With the help of these units, it is possible to bring new ballast to the worksite.
• The cutting chain excavates the ballast and passes it on to the screening unit.
• Here the reusable ballast is separated from waste material.
• A system of conveyors transport the waste material to the end of the machine, where it is discharged.
• The cleaned ballast is mixed with the pre-dumped, picked-up and stored ballast and put back to the track directly behind the cutter chain.
• When working in curves, the shaker boxes can be adjusted to compensate for superelevation.
• With the RM 802, production rates of up to 2,000 feet per hour are achievable.
