ROPS/FOPS Certified Cab


  • 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.
