301706 - Miller Off-Road Running Gear for Bobcat 230/265 with Never Flat Tires

Technical Overview of Miller 301706 Off-Road Running Gear

The Miller 301706 Off-Road Running Gear is a specialized transport solution engineered specifically for the Miller Bobcat 230 and Bobcat 265 engine-driven welding machines. This undercarriage system is designed to address the logistical challenges of moving heavy industrial equipment across uneven, unpaved, or debris-strewn environments typical of construction sites, pipelines, and field fabrication zones. The core technical differentiator of this running gear is the integration of "Never Flat" tire technology. Unlike traditional pneumatic tires which rely on compressed air and are susceptible to pressure loss via punctures or valve failures, these tires are foam-filled. This construction ensures that the tires maintain their structural integrity and load-bearing capacity regardless of the terrain conditions or the presence of sharp hazards such as nails, scrap metal, or jagged rocks.

The assembly features four heavy-duty tires with a 15-inch diameter. This large diameter is critical for increasing the angle of approach and departure, allowing the welder to traverse obstacles, ruts, and mud that would immobilize smaller caster-style wheels. The increased ground clearance provided by the 15-inch wheels protects the underside of the welder unit from impact damage during transport. The running gear includes a rugged, heavy-duty handle that provides the necessary leverage to maneuver the substantial weight of a fully fueled Bobcat welder equipped with welding leads. The handle design promotes ergonomic force application, reducing the physical strain on operators during repositioning.

Compatibility is strictly defined for the Bobcat 230 and 265 models, ensuring that the mounting points align perfectly with the welder's chassis for a secure and balanced center of gravity. This precise fitment prevents the instability often associated with universal carts. By eliminating the variable of tire pressure maintenance, the Miller 301706 ensures that the running gear is always operational, thereby removing a potential point of failure in critical field operations. The system is designed to support the static and dynamic loads imposed by the welder, ensuring longevity and reliability in professional industrial applications.
