Equipment Highlights

ACHIEVE GREATER PRODUCTIVITY
        
  • Haul your materials faster with an accelerated travel speed.
    •     
  • Put more power to the ground with increased torque.
    •     
  • Enjoy greater productivity while using a more responsive Traction
    Control System (TCS).
    •     
  • Reduce tire wear with maximum by engaging TCS early in the slip.
    •     
  • Strong, predictable performance helps operators achieve the lowest cost per ton.
BOOST FUEL EFFICIENCY
        
  • Up to 13% less fuel consumption.
    •     
  • Advanced Productivity Electronic Control System (APECS) allows the engine and transmission to communicate on a high level. This communication allows the machine to better utilize the power andtorque the engine is producing.
    •     
  • Automatically optimize fuel consumption with the feature—Adaptive Economy mode reduces fuel use without affecting productivity and can be engaged with a single button.

    •     
  • External payload indicator lights alert the loader when to stop, reducing the risk of machine overloading.
    •     
  • Product Link™ system connects to each machine wirelessly, 
    allowing you to monitor location, hours, fuel use, productivity, idle
    time, and diagnostic codes.
    •     
  • VisionLink®
    wirelessly connects you to your equipment, giving
    you access to essential information you need to know to run your business.
    •     
  • The Cat 773 is MineStar™ ready and includes Cat Product Link
    Elite and VIMS to help optimize equipment management, remote
    monitoring capabilities, machine availability, and component life while reducing both repair costs and the risk of catastrophic 
    failure.
    •     
  • Tons kilometers per hour/tons miles per hour (TKPH/TMPH) tire
        management system works with TPMS for improved tire life. 
REDUCED MAINTENANCE COST AND OTHER COSTS
        
  • Grouped service points.
    •     
  • Control particulate matter with two engine-mounted diesel oxidation catalyst canisters. (Tier 4)
    •     
  • NRS technology replaces a portion of intake air with exhaust gas to control combustion temperatures and NOx production. (Tier 4)
    •     
  • Parts commonality with other Cat equipment.
    •     
  • Resolve problems before failure occurs with VIMS notifications.
    •     
  • Autostall enables quick operating temperatures for best performance life.

APPLICATION VERSATILITY
        
  • Get the right body option—Dual Slope, Flat Floor, or Quarry—for your material and jobsite needs.
    •     
  • For haul profiles including steep slopes, an optional Dual Slope body is available—offering excellent material retention.
    •     
  • The flat floor body is perfect for metering material, especially when
        feeding the crusher.
