High volume output and a quality track

The FRM 802 is a High-Capacity Shoulder Cleaning Machine specially designed to work independently or in conjunction with the Plasser RM 802 High-Capacity Undercutting/Cleaning consist on track with pre-dumped ballast. Together these machines produce high volume output and a quality track. The two pick-up chains pick up the shoulder material and transfer it via conveyors to the dual shaker screening system. Conveyors transport the waste material to the front end of the machine where it is discharged. When working together with the RM 802, the cleaned ballast is transported via a series of conveyors to the rear of the machine and passed on to the Ballast Pickup Unit where it is mixed with the picked-up, pre-dumped ballast. The mixed ballast then continues via several more conveyors on multiple machines to the RM 802, where it is put back to the track.
