R1300G Underground Mining Loader

The Cat® R1300G is our smallest underground loader, but with a breakout force of 12 020 kg (26504 lb) and 117 kW (157hp) of engine power, it brings maximum production capability to smaller mines. Productivity is enhanced thanks to a smaller turning circle compared to competitive machines. It offers a larger fuel tank so it can run longer between refilling, and superior bucket reach and bucket dump for better loading and faster emptying.
An operator favorite, the R1300G features excellent loaded weight distribution, ride control and seat suspension for maximum comfort. And to raise the bar on air quality in your mine, you can equip your R1300G with an optional diesel particulate filter. The R1300G is an ideal match for the Cat AD22 truck.


  • Large window openings for increased visibility.
  • Large grab handles on both sides to provide 3-point access to cab and machine.
  • 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, lift arm support pins, ground-level compartment sight gauges, transmission oil dipstick located away from articulation point, and secondary engine shut-off switch at ground level.


  • Optional enclosed design that provides fresh, pressurized, temperature-controlled air circulation with air conditioning.
  • Optional sound-suppressed 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.


  • Electronically controlled power shift transmission that delivers smooth, responsive tramming performance.
  • 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.
  • Superior bucket reach and bucket dump for better loading and faster bucket emptying.
  • 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.


  • Efficient and powerful Cat 3306B engine, which delivers maximum performance in the most demanding mining applications and is tolerant to contamination and compatible with high-sulfur fuels for worldwide use.
  • 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.
  • Optional factory-installed remote-control system.


  • Buckets designed for optimal loadability and structural reliability, with four dump bucket sizes and one ejector bucket option — all designed and manufactured to match their performance capabilities.
  • Welded, bolted or hammerless Ground Engaging Tools (GET) to meet site-specific needs and fit with site maintenance strategy.
  • Cat Modular Segment Welded 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 features a bolt-on design that enables fast and easy removal and replacement.
  • 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 cable in outer articulation area, and color- and number-coded wires.
  • Cat 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 in the most demanding conditions.


  • 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 Flow-Through Diesel Particulate Filter (DPF), which delivers a greater than 50% Diesel Particulate Matter (DPM) reduction in the exhaust.
  • Cat Rebuild and Cat Reman programs, which preserve raw materials, conserve energy and reduce emissions.
  • Retrofits and upgrades, which enhance and improve older machines to incorporate efficiency improvements and emission reductions, and to keep them in production longer to conserve energy, lower emissions and minimize the need for raw materials.
