When it came time to redesign the Cat® R1700 Underground Loader, the goal was simple: add value, power and performance, and keep safety at the core. And we succeeded. With each cycle, the R1700 hauls 20% more material than its predecessor and is highly aggressive in the pile. It loads, climbs, hauls and dumps faster. And it’s factory ready for the latest technologies, including fully autonomous haulage, which takes safety and efficiency to a new level. The R1700 is infused with features to keep people safe. It offers three engine emission options, including one that meets Stage V standards, and can be tailored to your mine’s ventilation requirements. A clean-sheet redesign, the R1700 loader leverages engineering talent from across Caterpillar to create the next generation of productive underground loading.

SAFETY
Improvements in visibility, with lighting and camera coverage, including optional reverse operation camera with color display, multiple windshield wipers, and standardized LED lights that provide illumination to the front and rear.
Factory-ready for fire suppression, dedicated canister area estate and multiple fire suppression activation points, including from within the cab.
Improved access and egress with anti-slip tread on all walking surfaces, newly redesigned handrail system with full coverage and dual secondary emergency exits.
Operator Present System, which protects the machine and operator from uncontrolled machine movements, with hydraulic system neutralization and door sensor.
Safer service with service area located on cold side of engine, thermal protection on aftertreatment components, integrated lock-out/tag-out points, front linkage pins for locking the lift arms in place, and bolt-on tow hooks.
OPERATOR COMFORT & CONTROL
Completely redesigned cab with more space, with operator seated lower to improve ride quality and head room; adjustable padding for the operator’s knees; and additional foot-space during pedal operation.
Climate control standard with pressurized enclosed option; all new HVAC coverage with improved airflow, greater defrosting coverage and reduced noise levels.
Improved ergonomics on all controls, easy-to-use joystick controls, and an isolation-mounted cab to reduce vibration transfer to the operator.
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.
PRODUCTIVITY & PERFORMANCE
Fast cycle times thanks to integrated ride control system, which gives operators confidence to travel at speeds above 5 km/h (3 mph) during load and carry operations.
Hydraulic system that provides significantly more breakout force during digging, and that gives the machine faster dumping times at the other end of the cycle.
Repositioned front linkage cylinders for better mechanical lift.
Features that deliver excellent responsiveness, such as Auto Dig, which automates loading of the bucket; and pilot-controlled steering system to provide more acute feel in tight spaces.
Hydraulically actuated auto retarding, which improves cycle times as operators gain confidence and become more comfortable on downhill grades at faster speeds.
POWER & EFFICIENCY
C13 engine that is larger than previous model for more power and performance, with 6-cylinder configuration that is turbo-charged and air-to-air aftercooled.
New lock-up clutch torque converter that engages automatically as the machine shifts into second gear.
Mechanically Actuated, Electronic Unit Injection (MEUI™) high-pressure, direct injection fuel system, which electronically monitors operator demands and sensor inputs to optimize engine performance and fuel combustion.
State-of-the-art hydraulic system, which uses on-demand piston pumps for durability, higher pressures and overall system efficiency, and provides full system pressure for operator while the engine is at idle.
Newly resized Cat transmission governed by APECS software, which allows the transmission to comfortably shift under higher torque conditions and makes it possible for the machine to climb grades more quickly by reducing lost momentum between shifts.
BUCKETS AND G.E.T
Newly patented bucket design that offers load path management for long wear life, increased throat angle for easier loading in rock, improved tire coverage for cleanup and tire protection, added strength to match improved breakout force, and added stiffness to inside torque tube for torsional rigidity.
10 bucket options, including six dump bucket sizes, one light material bucket, one ejector bucket option and two bolt-together options — all designed and manufactured to match their performance capabilities.
Three types of Ground Engaging Tools (GET) available: modular weld-on, which deliver welded part reliability; Bolt-On-Half-Arrow (BOHA), which offer more wear material and feature a bolt-on design that enables fast and easy removal and replacement; and the Durilock Lip Shroud system, featuring hammerless installation and maintenance-free retention of GET, with three interchangeable shroud styles.
Cat Bucket Pro App, which provides real-time data on GET performance to help you plan maintenance, manage inventory and know cost-per-ton.
RELIABILITY & DURABILITY
Front frame section with four-plate design that offers new, fully integrated front axle support casting that absorbs greater impact, vibration and tram loads that come with the growth of the machine capacity and weight.
Increased axle housing thickness for abrasion protection and corrosion resistance.
Visibly stronger lift arms with additional steel thicknesses, 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.
SERVICEABILITY
ECMs located in single, air-cooled and sealed box located on the service platform of the machine, providing clean, simplified electrical routings throughout the machine and greatly improved access and convenience for service personnel.
Redesigned hitch with simplified hydraulic routings and more space for technicians to work and clean.
Modular components that can be removed from the machine and slotted back into place as a single unit, allowing the machine to get back into service much more quickly.
Improved service access, with swing-open radiator guard, and filter and key service tasks grouped into centralized service section with oil coolers and batteries located just below.
Fuel tank that bolts in to the frame, allowing it to be easily cleaned or replaced if damaged as it bolts in to the frame.
TECHNOLOGY
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; co-pilot, which requires only directional input from the operator; and fully autonomous operation.
High-resolution dash displays with 11 language options for access to real-time system information.
In-cab health monitoring visible on the digital display and monitored through the Cat Product Link™ Elite (PLE) system, including integrated MineStar Health offerings that enable proactive maintenance services and predictive equipment analysis.
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.
SUSTAINABILITY
Three engine emission options, including EU Stage V, Tier 2 and Tier 3, which reduce emission of NOx and particulates.
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 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.
