AD63 Underground Articulated Truck

The Cat® AD63 Underground Truck is designed for high production, lower costs and increased efficiency. It’s built tough to stand up to the harsh conditions of your site, and features a number of improvements over its predecessor, including a 5% greater payload and more torque. The world-class cab keeps operators safe and comfortable all shift long, and new enhancements help ensure the safety of everyone working in, on or around the machine. It’s powered by a Cat C27 engine that meets EU Stage V Emissions Standards for cleaner performance, as well as reduced ventilation costs. And its rugged construction and simplified maintenance make for longer life and lower operating costs, so you can get the most out of your investment.


  • Standard Operator Present System, which protects the machine and operator from uncontrolled machine movements, with hydraulic system neutralization and door sensor.
  • Safer access and egress with anti-skid upper deck surfaces, new and improved upper deck handrails, 3-point cabin and machine access, additional access via the front grill and alternate exit via windows.
  • Integrated Cat braking system that delivers reliable performance and control, plus service brake system actuated by hydraulic pressure and parking brake function that is spring applied and hydraulic released to ensure braking in the event of loss of hydraulic pressure.
  • Safer service with steering frame lock, body retaining pins, exhaust heat shielding and firewall fitted, plus hitch hydraulic hoses fitted with burst protection sleeves.


  • Controls, levers, switches and gauges positioned to maximize productivity and minimize fatigue.
  • Standard sound-suppressed enclosed ROPS cab for a quiet, secure and comfortable air-conditioned working environment with fresh, pressurized, temperature-controlled air circulation.
  • Ergonomic, fully adjustable suspension seat with thick cushions that reduce pressure on lower back and thighs and wide, retractable seat belts that provide a secure, comfortable restraint.
  • Comfort wheel with tilt steering that provides a comfortable driving position, secure grip and greater control.
  • Rollover Protective Structure (ROPS) and Falling Objects Protective Structure (FOPS) resiliently mounted to the mainframe to isolate the operator from vibration for a more comfortable ride.


  • 63-tonne (69-ton) payload that is 5% larger than its predecessor, the AD60 for more material carried every cycle for maximum production.
  • Mechanical powertrain and power shift transmission that offer unmatched operating efficiency and control on steep grades and in poor underfoot conditions.
  • Automatic Retarder Control (ARC), which electronically controls retarding on grade, allowing the operator to maintain optimum engine speeds for faster downhill hauls and greater productivity.
  • Single-stage hoist cylinders that provide fast dump cycle times of 13 seconds for raise and 24 seconds for lower.


  • Powered by a Cat C27 engine with an EU Stage V emission rating to comply with emissions regulations while providing unmatched power.
  • Increase of engine torque rise from 18% to 28%, coupled with a powertrain ratio update to spread the torque rise, for superior grade holding capability.
  • Cat Data Link, which decreases fuel consumption, regulates engine speed and prevents shifting above a pre-programmed gear while the body isn’t fully lowered.
  • Torque converter lock-up clutch that combines the high rimpull and smooth shifting of a torque converter drive with the efficiency and performance of direct drive.
  • Modular HVAC system with dual power options —operates when engine is running to provide maximum efficiency in hot applications and is powered by the electric system when the engine is turned off, for less engine idling and lower operating costs.


  • Cat truck bodies designed for optimal strength, capacity and durability.
  • Designed and matched with the integrated chassis system for optimum structural reliability, durability and long life.
  • Five body size options, including new lightweight dump body, for the most efficient hauling solution at the lowest cost per ton.


  • Box-section frame design with stiff frame beams to resist twisting forces; weld joint and materials matched to optimize structural life.
  • Two independent variable rebound suspension cylinders that dissipate haul road forces for longer frame life and a comfortable ride.
  • Articulating / oscillating hitch that provides steering and oscillation and enables the truck to maintain all-wheel ground contact in rough terrain.
  • Frame, powertrain, engine and components that are built to be rebuilt, delivering second and third lives.


  • Ability to tilt the cab for improved access to the cab side of the engine, improved access to brake accumulator and engine mounting hardware, plus access to alternator and starter motor without removing belly plates.
  • Ground-level access to all tanks, filters, lubrication points and compartment drains; remote mounted fuel filters for easier serviceability; and fluid-level sight gauges.
  • Radial seal air filters that are easy to change, reducing time required for air filter maintenance; plus upsized radiator surround has to improve access to pre-cleaner and filters.
  • Electrical connectors that are sealed to lock out dust and moisture, harnesses that are covered for protection, and wires that are color- and number-coded for easy diagnosis and repair.


  • Product Link™ Elite (PLE) network management module, which stores and transfers data and serves as a connectivity enabler for dealer-provided condition monitoring services and integrates with Cat MineStar Fleet and Health for diagnostic and equipment management.
  • Optional MineStar Fleet for underground, which provides real-time visibility to cycle time, payload, machine position and other key operational parameters; and MineStar Detect, which uses a proximity detection system coupled with a revolutionary communications and tracking network to prevent incidents and track people and machines in real time.
  • Truck Payload Measurement System, which automatically records load cycle information when the load is dumped, giving operators real-time loading data and sorting it for download.
  • Cat Electronic Technician (ET), which enables quick electronic diagnosis of machine performance and key diagnostic data for effective maintenance and repairs.
  • Cat Electronic Monitoring System (EMS), which provides continuous access to critical machine data to keep the machine performing at a high level.


  • Cat C27 EU Stage V engine that meets the strictest emission standards and is approved by CANMET; does not require Diesel Exhaust Fluid (DEF) to meet standards.
  • Optional Cat Diesel Particulate Filters, which further reducing particulate matter in the exhaust.
  • Ongoing research and development into engine compatibility with diesel fuel blended with lower-carbon intensity fuels such as biofuels and renewable fuels, plus power options like electrification.
  • Cat Rebuild and Cat Reman programs, which preserve raw materials, conserve energy and reduce emissions, plus retrofits and upgrades for older machines to incorporate efficiency improvements and emission reductions.
