Frame: MTI/NexTec locomotive frames are unique structurally sound welded frames utilizing CNC cut quality steel carefully inspected and specified. On completion of fabrication all frames are blasted in a large Wheelabrator which removes blemishes and allows detailed inspection of all welds and bend lines to ensure structural integrity.

Wheels: All wheels are cast from a high grade of abrasion resistant steel to MTI specifications. Wheels are mounted via fasteners to wheel hubs. The wheel hubs are spline fitted to the axles to ensure the highest integrity of fit..

Axles: MTI/NexTec axles are designed for maximum loads and are carefully manufactured from high quality alloy steel with high factors of safety. Axles are press fit and keyed to main drive worm wheels.

Gearing: All MTI/NexTec Locomotives are manufactured utilizing time tested and proven double enveloping worm gears. These gear systems have a long history of application in military, petroleum, crushing and many other applications requiring high power density combined with heavy duty reversing applications. Since 1998 the double enveloping worm gear systems have been proven in locomotive applications in mining, tunneling and industrial applications .The gear set being utilized on the 60HP / 45KW drives are rated for heavy duty application gear drive systems up to double that rating.

Suspension: The standard suspension used by MTI / NexTec Locomotives is a chevron suspension designed around parameters well known to the locomotive industry and proven in countless mine and tunnel rail haulage applications.
