Features At A Glance

Displaying 1-6 of 7

ACHIEVE GREATER PRODUCTIVITY

ACHIEVE GREATER PRODUCTIVITY

• Haul more material per cycle, faster, and burn less fuel per cycle
• Industry first frame design that reduces empty weight, delivering potential for larger payloads and lower fuel burn
• Rolled form body with 10% more body volume to optimize target payload
• Double A-type front suspension design highly impacts operator comfort with far superior ride and handling for faster cycles
• Proven high mechanical uptime with a robust carryover of high-value driveline components of the proven generation of 775 series machines, allowing for more operating hours per year.
BOOST FUEL EFFICIENCY

BOOST FUEL EFFICIENCY

• Reducing the empty weight of the machine enhances payload capacity per liter/gallon of fuel during loaded cycles and decreases fuel consumption during empty cycles, improving overall fuel efficiency.
• Enhanced ride and handling allow for higher speeds on curves and driving in higher gears, which directly reduces fuel consumption during the cycle.
• APECS (Advanced Productivity Electronic Control Strategy) enables high-level communication between the engine and transmission, optimizing power and torque utilization.
• Optimize fuel use with adaptive economy mode, reducing consumption while maintaining productivity, activated by a single button.
• Achieve enhancements in fuel efficiency with automatic neutral idle.
• Operate your truck at an engine speed and gear selection that maximizes fuel efficiency, incorporating speed limiting measures.
• The integrated engine idle shutdown feature conserves fuel by automatically activating when the truck is parked and has been idling for a predetermined period.
DESIGNED FOR SAFETY

DESIGNED FOR SAFETY

• 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.
• Four-point seat belt provides enhanced safety to the operator.
• The seat belt indicator provides visual and audible alerts when the seat belt is unfastened and is also equipped with an external seatbelt beacon.
• Lockout features help the service technician perform maintenance work on the machine in safe mode.
• Secondary steering activates automatically in case of primary system failure.
• Overload speed limiter works with the truck's payload system to automatically reduce the machine's speed when the truck is overloaded. 
• Hill Start Assist with Anti Roll Back keeps the truck from moving on slopes. It stops the truck from rolling the wrong way when you change gears and helps reduce potential accidents.
WORK IN COMFORT

WORK IN COMFORT

• 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 easy automotive-quality shifting with the new transmission controls.
• Automatic cab temperature controls.
• The Cat next-generation deluxe seat is designed to enhance operator comfort. An optional premium leather seat with heating and cooling functions is also available as an attachment.
TECHNOLOGY THAT GETS WORK DONE

TECHNOLOGY THAT GETS WORK DONE

• Integrated systems give you the ability to make timely, fact-based decisions to maximize efficiency, improve productivity, and lower costs.
• Gain valuable insight into how your machine is performing by continuously monitoring and collecting vital machine data via the advisor display with the software Vital Information Management System (VIMS™). Applicable to both U.S. EPA Tier 4 Final/EU Stage V and U.S. EPA Tier 2 equivalent.
• The Cat payload system records reliable material weights, stores up to 2,400 payload cycles, and generates reports on weight, haul cycle time, and distance with date and time stamps.
• Optional external payload indicator lights and external scoreboard provide clear alerts to the loader regarding when to halt loading, reducing the likelihood 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.
• VisionLinkTM wirelessly connects you to your equipment, giving you access to the 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.
• The tire management system, which measures tons kilometers per hour or tons miles per hour (TKPH/TMPH), operates alongside the tire pressure monitoring system (TPMS) to help maintain tire longevity.
REDUCED MAINTENANCE COSTS AND OTHER COSTS

REDUCED MAINTENANCE COSTS AND OTHER COSTS

• 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.
