PrintAdditional Information
Both single- and tandem-axle TMAX 3 models feature aluminum construction for corrosion resistance and increased payload. For added capabilities and convenience, the crane pedestal/compartment is constructed of steel material capable of handling the robust lifting capacity of Stellar’s 14530 crane while providing the same storage space as other, non-reinforced compartments.
- Available in either 14′ or 17.5′ bodies.
- 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.
- Mounting rails integrated within compartments allow for fully customizable configurations.
- Aluminum sidepack and doors reduce weight and corrosion, allowing for more payload and longer life.
- Ease of wiring access with added pre-drilled holes between compartments for seamless wiring installation.
- Bodies feature a 26″ 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.
- Easily add a wide range of mechanic service truck accessories, like bale handle drawer sets and bolt bins for better organization.
- 3-point compression latches keep weather-stripping tight while allowing easy access.
- Drawer sets with 16″ bale-style pull handles are incorporated into compartments for better organization.
- 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.
- Hydraulic reservoir design features a top-mounted filter for easier maintenance.
- Complete undercoating, with minimum of 6.5 mils of petroleum base material, provides extra protection from corrosion and road debris.
- Mudflaps positioned to wire guards to avoid interference with exhaust systems.
Models:
- TMAX 3-14
- TMAX 3T
