Product Details

The HART-408 is a diesel hydrostatic personnel transport designed for use in a non-permissible underground setting. Its sole purpose is to safely carry up to 8 passengers to their destination while providing a smooth ride. Features include an onboard diagnostics and control system, comfortable padded seating, aggressive all-terrain tires, and available four wheel steering. The HART408 also has two opposing operator locations, one forward and one aft. This reduces the need reversing and turning around, especially in tight places. The chassis platform can also be outfitted for purposes other than personnel transportation. Please contact us.
