Benefits & Features
Engine
The Cat® 3176C is a proven engine that delivers reliability and durability. The efficient and powerful engine delivers maximum loading and tramming performance in most demanding mining applications. Complete system integration of the engine and transmission ensures fuel efficiency and smooth operation.
High Torque Rise
Provides unequalled lugging force while digging, tramming and traversing steep grades. Torque rise effectively matches transmission shift points for maximum efficiency and fast cycle times.
Turbocharged and Aftercooled
Air-to-air aftercooling provides improved fuel economy by packing cooler, denser air into cylinders for more complete combustion of fuel and lower emissions.
Electronic Unit Injection
The electronically controlled unit injection fuel system senses operating conditions and regulates fuel delivery for optimum fuel efficiency. The proven high-pressure fuel system provides improved response times and more efficient fuel burn with lower emissions and less smoke.
Pistons
Oil cooled pistons increase heat dissipation and promote longer piston life.
Radiator
Modular radiator with swing-out grill provides easy access for cleaning or repair. Built in sight gauge allows for quick, safe coolant level checks.
Power Train – Engine
The Cat® 3176C engine is built for power, reliability and efficiency. »Learn More
Power Shift Transmission
The Cat four-speed planetary power shift transmission is matched with the 3176C diesel engine to deliver constant power over a wide range of operating speeds.
Robust Design
Designed for rugged underground mining conditions, the proven planetary power shift transmission is built for long life between overhauls.
Torque Converter
High capacity torque converter delivers more power to the wheels for superior power train efficiency.
Electronic Autoshift Transmission
The electronic auto shift transmission increases operator efficiencies and optimizes machine performance. The operator can choose between manual or auto shift modes.
Transmission Neutralizer
Using the left brake pedal, the operator can engage the service brakes and neutralize the transmission, maintaining high engine rpm for full hydraulic flow, enhancing digging and loading functions.
Final Drives
Cat final drives work as a system with the planetary power shift transmission to deliver maximum power to the ground. Built to withstand the forces of high torque and impact loads, double reduction final drives provide high torque multiplication to further reduce drive train stress.
Axles
Heavy duty axles are built rugged for long-life in the most demanding environments.
Oscillating Rear Axle
Oscillating rear axle ensures four-wheel ground contact for maximum traction and stability at all times.
Differential
No spin rear differential reduces tire wear and maximizes traction in uneven terrain.
Brakes
Fully enclosed oil immersed disc brakes incorporate independent service and parking brake pistons. Hydraulic actuated independent circuits provide improved performance and reliability.
Power Train – Transmission
More power to the ground for greater productivity. »Learn More
Hydraulic System
Powerful Cat hydraulics deliver exceptional digging and lifting forces and fast cycle times.
Lift and Tilt System
High hydraulic flow rates provide fast hydraulic cylinder response and powerful lift forces. Large-bore tilt and lift cylinders deliver exceptional strength, performance and durability.
Pilot Controls
Low effort, pilot operated joystick implement control with simultaneous lift and tilt functions optimizes operating efficiency. Optional hydraulic controls enable an ejector bucket to be controlled from a switch on the bucket control joystick.
Steering System
STIC™ control system integrates steering and transmission functions into a single controller for maximum responsiveness and smooth control.
Optional Ride Control
Automatic Ride Control enhances machine ride and performance at speeds above 5 km/h (3 mph).
Cat Hydraulic Hose
Field proven Cat high pressure XT™ hydraulic hose is exceptionally strong and flexible for maximum system reliability and long life in the most demanding conditions. Reusable couplings with O-ring face seals provide superior, leak free performance and prolong hose assembly life.
Hydraulics
Cat hydraulics deliver the power and control to keep material moving. »Learn More
Frame Design
The frame is engineered to withstand extreme forces generated during loading and tramming cycles. A precision manufacturing process ensures every structure is consistently built to high quality. Deep penetration and consistent welds throughout the frame ensures structures are solidly fused to provide a sturdy platform for the linkage and the axles. The bores and the surfaces are precisely machined for perfect alignments for the pins and precision mating surfaces for major components resulting in durable frames that allow complete machine rebuild for 2nd or 3rd life.
Z-Bar Loader Linkage
Proven Z-Bar loader linkage geometry generates powerful breakout force and an increased rack back angle for better bucket loading and material retention. Heavy duty steel lift arms with cast steel cross tube ensures extreme loads encountered during loading and tramming are efficiently dissipated for long service life.
Sealed Pins
Sealed colleted pins are fitted to all bucket and lift arm hinge points for longer pin and bushing life. This reduces maintenance costs and extends service intervals. The sealed joints retain lubrication and prevent contaminant entry.
Hitch
Spread hitch design widens the distance between upper and lower hitch plates to distribute forces and increase bearing life. Thicker hitch plates reduce deflection. The wide opening provides easy service access. Upper and lower hitch pins pivot on roller bearings to distribute horizontal and vertical loads over a greater surface area. Shim adjusted preload reduces maintenance time. An on-board steering frame lock pin is fitted to prevent articulation during maintenance and service.
Structures
Rugged Cat structures – the backbone of the R1600G’s durability. »Learn More
The operator station is ergonomically designed for total machine control in a comfortable, productive and safe environment. All controls, levers, switches and gauges are positioned to maximize productivity and minimize operator fatigue.
Protective Structure

Optional Enclosed Cab
Optional sound-suppressed ROPS cab provides a quiet, secure working environment. Large window openings offer excellent visibility in all directions. Enclosed design provides fresh, pressurized, temperature-controlled air circulation with air condition for a more comfortable working environment.
STIC™ Steering and Transmission Integrated Control
STIC™ provides effortless control of the complete mobility of the machine by single controller. Simple side-to-side motion articulates the machine. Directional shifting (forward/neutral/reverse) is controlled using a three position rocker switch. The thumb operated buttons control gear selection.
Dual-Pedal Braking
Dual brake pedals function as a brake and a transmission neutralizer so the operator can maintain high engine rpm for full hydraulic flow and fast cycle times.
Monitoring System
Cat® Electronic Monitoring System (Cat EMS) continuously provides critical machine data to keep the machine performing at top production levels.
Message Center. Three-category warning system alerts operator of abnormal machine health conditions.
Gauge Cluster. Maintains a constant display of vital machine functions.
Speedometer/Tachometer Module. Monitors three systems: engine speed, ground speed and gear indicator.
Pilot Controls
Low-effort pilot operated joystick controls integrate steering, transmission and implement functions for smoother, faster cycles with less operator fatigue.
Suspension Seat
Ergonomic, fully adjustable suspension seat provides optimal operator comfort. Thick cushions reduce pressure on lower back and thighs. Wide, retractable seat belts provide a secure, comfortable restraint.
Operator Comfort
Ergonomically designed for all-day comfort, control and productivity. »Learn More
