For servicing big fleets in demanding industries, such as heavy equipment, mining and construction, you need a mechanic truck with a bring-it-on attitude. That’s the TMAX 3. Quality-built with the latest engineering, top materials and precision assembly, TMAX 3 Mechanic Trucks can handle the daily — and weekly, monthly and yearly — grind in the toughest working conditions.


Additional Information

Both single- and tandem-axle TMAX 3 models are available. For outstanding durability, their shells are built with rugged 12-gauge, two-sided A-40 galvanneal steel. For added capabilities and convenience, the crane pedestal/compartment is constructed of steel material capable of the robust lifting capacity of Stellar’s 14530 crane while providing the same storage space as other, non-reinforced compartments.

  • Available in 14′ steel or aluminum bodies.
  • Tandem axle models available in 17.5′ steel body.
  • Stellar’s torq-isolator crane support design isolates the crane compartment from the rest of the side pack.
  • Lifting stresses are transferred to the stabilizers and box-type subframe, not the compartment doors.
  • Aluminum extruded top with drill-free mounting rails make it easy to add a wide range of mechanic service truck accessories.
  • Aluminum sidepack and doors reduce weight and corrosion, allowing for more payload and longer life.
  • Bodies feature a 30″ steel workbench bumper with an integrated full-width long bar storage compartment and vise mounts.
  • Roller-type boom support helps center the crane boom when stowing.
  • Stainless-steel billet-style hinges have hidden fasteners and a rugged 5/16″ stainless-steel rod for years of heavy use.
  • Rotating master-lock system for security.
  • Exterior mounted light box provides easy mounting for lights and other accessories while minimizing entry points into the body.
  • 3-point compression latches keep weather-stripping tight while allowing easy access.
  • Double-panel 1/8″ aluminum tailgate with hinged arm brackets provides a stout working surface.
  • 250-lb capacity, adjustable divider shelves made of spangled galvanized steel.
  • Complete undercoating, with minimum of 6.5 mils of petroleum base material, provides extra protection from corrosion and road debris.
  • Easily add a wide range of mechanic service truck accessories.

  • TMAX 3T (tandem axle, steel)
