Boniface Interstater MK6

To tow many of today’s modern trucks and coaches with moulded components and aerodynamics, operators need a low profile under-lift that copes with long overhangs and the capacity to lift heavy weights. The Boniface Interstater MK6 has met the challenge with a proven track record reaching back over 30 years.

The Interstater’s Maxireach H or I under-lifts are both fabricated from specially quenched and tempered high tensile steel to provide strength without adding extra height or weight. Skilled craftsman assemble the components to exacting tolerances to ensure years of smooth operation and service under extreme conditions. Each under-lift goes through rigorous inspection and testing including lifting, extending and retracting under heavy loads.

With over 1,000 units in operation the Boniface Interstater is not only an industry favourite for heavy duty towing but has a built reputation as an extremely versatile unit that can also handle tough recoveries. The Interstater is equipped with rear outboard legs with pivoting feet that provides a flat pad or a spade depending on the surface conditions and is available with your choice of winches. For those difficult recoveries on narrow roads or to maintain minimal lane closures, your Interstater can be outfitted with The Sidewinder pivoting front legs and additional winches.
