APPLICATION VERSATILITY
• 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 traction by engaging TCS early in the slip.
• Strong, predictable performance helps operators achieve the lowest cost per ton.

• Improvements in accessibility with safe ground-level access to fuel fill and daily maintenance points.
• Ensure three points of contact when entering and exiting the machine with strategically placed walkways and grab rails.
• Superior brake performance meets the latest brake standards—ISO 3450:2011.
• The ground-level engine shutoff switch stops all fuel to the engine when activated and shuts down the machine safely.
• Sturdy 4-point mounted cabin meets rollover protective structure/ falling objects protective structure (ROPS/FOPS) standard.
• 4-point seat belt provides enhanced safety to the operator.
• Seat belt indicator implements both visual and audible alerts to the
operator when seat belt is not fastened.
• Lockout features help the service technician to perform maintenance work on the machine with safe mode.
• Secondary steering activates automatically in case of primary system failure.
• Overload speed limiter works with truck payload system to reduce machine speed automatically when the truck is overloaded.
• Completely redesigned cab for a whole new standard in visibility, comfort, and productivity.
• The new operator seat placement provides easier operation and comfort to the operator.
• Improvements in visibility gain enlarged views of the work area and its surroundings.
• Access connectivity and decrease clutter with more storage areas with the newly designed cab.
• Enjoy the easy automotive-quality shifting with the new transmission controls.
• Automatic cab temperature controls.
• Cat next generation deluxe seat for better operator comfort.
• Integrated systems give you the ability to make timely, fact-based decisions to maximize efficiency, improve productivity, and lower costs.

System (VIMS™). Applicable to both U.S. EPA Tier 4 Final/EU Stage V and U.S. EPA Tier 2 equivalent.
• Truck production management system (TPMS) provides accurate weighing of the materials, stores 2,400 payload cycles, and reports on weights, haul cycle times, and distances with date
and time stamps.
• External payload indicator lights/display 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 775 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.
• Grouped service points.
• Control particulate matter with two engine-mounted diesel
oxidation catalyst canisters. (Tier 4)
• NOx reduction system (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.
• Torque converter stall (autostall) enables quick operating temperatures for best performance life.
• All LED lights provide longer life, brighter light, consume less power, and are more resistant to vibration or water damage.
• Get the right body option—dual slope, flat floor, or quarry—for your material and job site needs.
• For haul profiles including steep slopes, an optional dual slope body
is available—offering excellent material retention.
• The X body’s flat floor is perfect for metering material, especially when feeding the crusher.
• Protect your truck’s body life in high-impact, hard rock applications with the optional rubber liner—available for dual slope and X bodies.
