Mitchell Rail Gear solves major problem of transporting mini excavator to railroad work site. The Mini Excavator can be towed on rail at speeds up to 45 mph then self-propel on the railroad rail head with full stability on railroad rail. During work cycles high speed travel is not required, but getting the machine to the work site requires high speed travel. Our tow position provides a means to transport the machine to the jobsite at high speeds without the need of an equipment trailer. Time is money and the faster you can move equipment to trouble spots on the railroad the faster the machine can go to work. Even a hydraulic driven mini-excavator can only travel 12-15 mph on rail with a rail gear system that is as much as 3 times the cost.
