2012 Mack Granite GU713 (6×4) is a heavy-duty, vocational powerhouse engineered for severe-duty applications like municipal snow plowing, highway maintenance, and high-capacity aggregate hauling. With a massive 68,800 lbs. Gross Vehicle Weight Rating (GVWR), this tandem-axle setup combines a high-torque Mack MP8 engine with a specialized Eaton Fuller multi-speed transmission and premium Beau-Roc/Tenco vocational equipment.
Engine & Powertrain Performance
- Engine: Mack MP8 12.7-Liter Overhead Camshaft 6-Cylinder Turbocharged Diesel.
- Power Output: 425 HP @ 1700 RPM with a massive torque profile designed to sustain heavy momentum up steep grades or through deep snow drifts.
- Fuel Efficiency & Emissions: Features Mack's ClearTech SCR (Selective Catalytic Reduction) system, meeting EPA 2010 emissions regulations while maximizing fuel economy.
- Engine Brake: Equipped with the PowerMax Maxidyne compression brake, delivering high retarding power to save service brakes during heavy down-hill hauling.
Eaton Fuller 8LL Transmission
- Gear Configuration: 8 forward speeds plus 2 "Low-Low" (LL) deep-reduction gears and 3 reverse gears.
- Deep Reduction: The 8LL pattern provides two ultra-low starting ratios designed specifically for high-torque, low-speed extraction in sticky mud, deep snow, or unpaved construction sites.
- Control: Manual shift with a pneumatic splitter on the gear shift knob to transition between low-range deep reduction and standard highway gears.
Cab & Chassis Architecture
- Cab Design: Mack’s standard galvanized steel vocational cab, engineered with laser welds and e-coat rust protection to survive harsh winter road-salting environments.
- Interior & Visibility: Features high-back air-ride seating, an ergonomic dash layout with easy-to-reach toggle switches for work lights, and a sloped hood design optimized for visibility over front-mounted snow plow hitches.
- Axle & Suspension Setup: 6×4 Drivetrain Configuration
- Front Axle: Heavy-duty steer axle riding on wide-footprint 425/65R-22.5 flotation tires to prevent the front end from sinking under the weight of the massive Tenco plow.
- Rear Tandem Axle: Dual-wheel configuration running 11R22.5 traction tires, distributing weight across a heavy-duty mechanical leaf-spring or air-ride vocational suspension.
Beau-Roc 13-Foot Steel Dump Body
- Load Capacity: 19-ton structural payload capability, designed with premium high-tensile steel to resist denting and abrasive wear from boulders, gravel, or asphalt.
- Body Design: Features a heavy-duty front bulkhead cab shield to protect the rear window, a robust dual-acting tailgate (top-hinged/dump or bottom-hinged/laydown), and heavy duty side-bracing.
- Hoist Mechanism: High-capacity telescopic hydraulic cylinder mounted underneath the front of the body, providing rapid lift cycles and safe dumping stability.
Tenco Winter Snow Plow Package
- Front Plow: Tenco 11-foot One-Way Snow Plow, designed with a high-curl moldboard to throw heavy, wet snow far off the right side of the highway at standard plowing speeds.
- Wing Plow: 11-foot Steel Snow Wing, mounted on the passenger (right) side of the chassis to clear shoulders, push back snowbanks, and widen the plowed path in a single pass.
- Hitch & Hydraulics: Integrated front-mount quick-disconnect plow hitch frame with heavy-duty lift cylinders, powered by a central hydraulic system driven via a front-engine PTO (Power Take-Off).
