• Hill assist system reduces potential for rollback by automatically holding brakes on when stopped on a grade. Cat 740 Articulated Haul Truck

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.
• Product Link™ system connects to each machine wirelessly, allowing you to monitor location, hours, fuel use, productivity, idle time, and diagnostic codes.
• Payload technology allows operators to view real-time load weights on the integrated display.
• External payload indicator lights alert the loader when to stop, reducing the risk of machine overloading.
• Stability assist software reports information via online VisionLink®, increasing awareness of machine history if a rollover has occurred.
• Advanced productivity gives you the ability to view trends to help improve bidding accuracy and profitability. Cat 740 Articulated Haul Truck

REDUCED MAINTENANCE COSTS

• Durable design and easier servicing mean maximized uptime and reduced service costs.
• Enclosed wet brake design keeps out contaminants, extending brake life (and increasing machine uptime), while reducing replacement cost.
• Universal joints are lubricated for life, eliminating any greasing during the product lifetime.
• Coolant formula improves component life by reducing corrosion.
• Entire machine is designed for greater ease of maintenance with side-tilting cab, electrically raised hood, access panels, and Cat Data Link connector.
• Radiator is mounted behind cab for protection and ease of access.
• AATC monitors and controls differential lock and wheel speeds. This reduces machine inefficiencies as well as driveline and tire wear. Cat 740 Articulated Haul Truck
