FEATURE

Proven Performance

Boost productivity with fully hydrostatic transmission.
Counter rotations, power turn and infinitely variable speed.
Larger fuel tank capacity for extending operation hours.
Better balance and stability with weight distribution with the center gravity optimization.
Robust and more powerful mechanical controled engine delivers superior durability and excellent fuel efficiency.

 

Exceptional Reliability

World class original pumps and motors.
Blades with high tensile strength steel and strong box-section design.
Reinforced structures, analyzed using Finite Element Analysis (FEA) .
Final drive with double-stage reduction and wet type brake.
Modular cooling system designed to endure -40°C to +48°C ambient temperatures.

Enhanced Reliability

Dual-path, hydrostatic drive system with electronic control technology from a world-class supplier delivers industry-leading reliability.
The Weichai mechanical engine with 7% increased power, offers classic durability and dependability.
Final drive adopts a double-stage reduction combined spur gear and planetary structure for high transmission efficiency to ensure a longer lifespan.
Machine structures are analyzed using Finite Element Analysis (FEA) and On Machine Stress Analysis (OMSA) to identify and reinforce  high-stress areas.
Equalizer bar and pivot shaft are pinned to the one-piece Track Roller Frame to increase ground clearance, along with three segmentation spring recoil system minimize impacts and prolong the undercarriage's life.
Wet type multi-disc brake system, delivers exceptional reliability and high braking performance, even under challenging operating conditions.

 

Outstanding Versatility and productivity

Compared to powershift machines, Caterpilar's proven electronic load-sensing system deliversheightened productivity.
Achieve seamless operations with functions like infinitely variable speed, counter rotation, and power turn, ensuring improved operational efficiency.
lmplement hydraulic system with pilot control helps adding operator comfort and precise control.
Modular and single-plane cooling system can endure extreme ambient temperatures ranging from -40°C to +48°C While offering superior fuel efficiency.
Larger fuel tank with 410 L capacity extends the operation hours to 2-3 working shifts.

Enhanced Operating Comfort

Spacious cabin space and fabric-covered seat offer a welcoming operational environment, delivering exceptional comfort and visibility.
Single multi-functional joystick ensures precise performance and maneuverability.
The brand-new F Series showcases a stylish design.
8' LCD main display with a great view of machine settings and features is easy to use.
Exceptional visibility for enhanced on-site awareness.

Lower operation cost

Integrated hydrostatic oil tank and hydraulic oil tank allow for longer maintenance intervals and reduced maintenance costs.
Electric Pressure Override (EPOR) function prevents high-pressure overflow and reduces heat load.

 

Leading in class serviceability

Maintenance-free and lifetime-lubricated idlers and track/carrier rollers provide simplified servicing, providing real value to our customers.
The Implement Distribution Valve, featuring a pressure testing port, is installed outside of the hydraulic oil tank for easy access to reduce overall maintenance time.
Standard diagnostic description on the display covering both the engine and hystat system allows for quick troubleshooting.
