2025 Caterpillar Wheel Dozers 844 Suppression
Mobile. Agile. Versatile.Maximize productivity in mining applications with the Cat® 844 Wheel Dozer, designed with efficiency in mind. Enhanced maintenance capabilities and simplified serviceability make for a long lifecycle, low owning and operating costs, and more uptime. Move more material with a machine built for the toughest conditions.
BenefitsIMPROVED EFFICIENCYLock-up torque converter, combined with an on-demand cooling fan and advanced engine idle management, delivers a more smooth shift
ENHANCED MAINTENANCEService access is conveniently located, helping to reduce maintenance time
ADDITIONAL SAFETYGrouped, ground level engine and machine controls allow for safe and easy daily maintenance
Features may include:
Long Term Value and Durability- The full box-section rear frame resists torsional shock and twisting forces.
- Solid through-width push beams transfer and absorb stresses through a larger portion of the frame.
- Robust structures withstand the toughest conditions and multiple lifecycles to help improve your bottom line.
- Experience reliable efficiency with complete control over injection timing, duration, and pressure with Mechanically Actuated Electronic Unit Injection (MEUI™).
- World-class Cat planetary powershift transmission features consistent, smooth shifting and efficiency through integrated electronic controls.
- Extended engine life and improved fuel efficiency with reduced rated speed.
- Battery disconnect, emergency engine shutdown, and stairway light switch are accessed through the ground level power service center.
- Cab-mounted LED strobes provide warning for others near the machine.
- Cab-mounted LED strobes provide warning for others near the machine.
- Integrated technologies assist with monitoring, managing, and enhancing your jobsite operations.
- Product Link™ remote monitoring helps provide valuable insight into machine or fleet performance through the VisionLink® interface, so you can make decisions that boost jobsite efficiency and lower operating costs.
- Vital Information Management System (VIMS™) touchscreen monitor gives access to a wide range of sensor information and enhanced machine data to resolve problems before machine failure.
- Steering and Transmission Integrated Control System (STIC™) combines directional selection, gear selection, and steering into a single lever, helping to maximize responsiveness and control while reducing operator fatigue.
- Operators can easily enter and exit the cab with fold-up STIC steer/armrest, reduced access stairway angles, and standard stairway lighting.
- Experience reduced vibrations with isolated cab mounts and seat-mounted implement and steering controls.
