The Cat® R1600H Underground Loader has a powertrain tuned specifically for speed on grade — mastering poor floor conditions and delivering maximum production in all speed ranges. It has the necessary strength and durability to work in tough conditions, but its precise controls and efficient operation set it apart. It offers superior stability, exceptional digging and lifting, and a variety of efficiency-boosting functions, plus a transmission that delivers constant power. The R1600H also offers a number of safety features, from FOPS/ROPS certified cab and safety glass to the ability to incorporate autonomous operation. Thanks to the extreme durability designed into the structure, the
loader can be productive through up to four rebuilds. The R1600H is an ideal match for the Cat AD30 truck.



  • Large window openings for increased visibility and large grab handles on both sides to provide 3-point access to cab and machine.
  • Operator Present System, which protects the machine and operator from uncontrolled machine movements.
  • Integrated Roll Over Protective Structure (ROPS) and Falling Object Protective Structure (FOPS) resiliently mounted to the frame.
  • Service brake system actuated by modulated hydraulic pressure, and parking brake function that is spring-applied and fluid-released, assuring braking in the event of loss of hydraulic failure.
  • Safer service with hot and cold side of engine, hinged belly guards, bucket control group safety pins, ground-level compartment sight gauges, and three engine shut-off switches at ground level.


  • Air conditioning provides fresh, pressurized, temperature-controlled air circulation.
  • Optional sound-suppressed ROPS cab for a quiet, secure working environment.
  • Controls, levers, switches and gauges positioned to maximize productivity and minimize fatigue, plus STIC™ system that makes it possible to control the complete mobility of the machine with a single controller.
  • Four corner oil-cooled braking system, which provides excellent control.
  • Oscillating rear axle, which ensures four-wheel ground contact for maximum traction and stability at all times, plus a no-spin rear differential that reduces tire wear and maximizes traction in uneven terrain.


  • High hydraulic flow rates that provide fast hydraulic and cylinder response and powerful lift forces, plus large-bore tilt and lift cylinders that deliver exceptional strength, performance and durability.
  • Electronic auto shift transmission, which increases operator efficiencies and optimizes machine performance.
  • Proven Z-bar loader linkage geometry, which generates powerful breakout force and an increased rack back angle for better bucket loading and material retention.
  • Optional ride control system that reduces fore and aft pitch of the lift arm and bucket, giving operators confidence to travel at speeds above 5 km/h (3 mph) during load and carry operations for fast cycle times.
  • Mechanically Actuated, Electronic Unit Injection (MEUI™) high-pressure, direct injection fuel system, which electronically monitors operator demands and sensor inputs to optimize engine performance.


  • Efficient and powerful Cat C11 engine, which delivers maximum tramming and loading performance in the most demanding mining applications.
  • Complete system integration of the engine and transmission to ensure fuel efficiency and smooth operation.
  • Unequalled lugging force while digging, tramming and traversing steep grades, plus torque rise that effectively matches transmission shift points for maximum efficiency and fast cycle times.
  • Superior powertrain efficiency thanks to high-capacity torque converter that delivers more power to the wheels.
  • Cat final drives that work as a system with the planetary power shift transmission to deliver maximum power to the ground.


  • Buckets designed for optimal loadability and structural reliability, with four dump bucket sizes, one ejector bucket option and one bolt-together option — all designed and manufactured to match their performance capabilities.
  • Cat Modular Segment Welded Ground Engaging Tools (GET) System, which deliver welded part reliability with the replacement simplicity of a mechanical system.
  • Bolt-On Half Arrow (BOHA) GET for bucket edges, which offer more wear material than standard weld-on GET, and feature a bolt-on design that enables fast and easy removal and replacement.
  • Additional wear packages, including sacrificial wear strips and Cat heel shrouds protect the edges from damage and reduce the need for costly bucket rebuilds.
  • Cat Bucket Pro App, which provides real-time data on GET performance to help you plan maintenance, manage inventory and know cost-per-ton.


  • Frame that is engineered to withstand extreme forces generated during loading and tramming cycles, with deep penetration and consistent welds throughout.
  • Oil-cooled pistons that increase heat dissipation and promote longer piston life.
  • Spread hitch design, which widens the distance between upper and lower hitch plates to distribute forces and increase bearing life, and thicker hitch plates reduce deflection.
  • Heavy duty steel lift arms with cast steel cross-tube to ensure extreme loads encountered during loading and tramming are efficiently dissipated for long service life.
  • Frame, powertrain, engine and components that are built to be rebuilt.


  • Reduced maintenance through more robust structures, modular and longer-lasting components, parts commonality, more accessible maintenance areas and extended service intervals.
  • Easier service access thanks to modular radiator with swing-out grill and ground-level access to all tanks, filters, lubrication points and compartment drains.
  • Downtime-reducing features such as radial seal air filters that are easy to change, built-in sight gauges for fluid level checks, sealed electrical connectors, covered harnesses, no cables in outer articulation area, and color- and number-coded wires.
  • Color Multi-Purpose Display (CMPD) along with Caterpillar Electronic Technician (Cat ET) service tool, which enables quick electronic diagnosis of machine performance and key diagnostic data for effective maintenance and repairs.
  • Field-proven Cat high pressure XT hydraulic hoses that are exceptionally strong and flexible for maximum system reliability and long life.


  • Factory-ready for remote operation and can be equipped with the industry-proven Cat MineStar™ Command for underground, which offers line-of-sight remote control, teleremote operation, and co-pilot, which requires only directional input from the operator.
  • Optional MineStar Fleet for underground, which provides real-time visibility to cycle time, payload, machine position and other key operational parameters.
  • Optional 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.
  • Optional integrated Cat MineStar™ Health offerings that enable proactive maintenance services and predictive equipment analysis.


  • 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.
  • Optional Ventilation Reduction (VR) Package, which incorporates selective engine hardware and software to reduce diesel particulate matter in the engine exhaust.
  • Cat Diesel Particulate Filter, which complements the VR engine by further reducing particulate matter in the exhaust.
  • Cat Rebuild and Cat Reman programs, which preserve raw materials, conserve energy and reduce emissions.
  • Retrofits and upgrades for older machines — to incorporate efficiency improvements and emission reductions, and to keep them in production longer to conserve energy and minimize the need for raw materials.
