Features At A Glance

PROVEN RELIABILITY

Cat C18 engine is built and tested to meet your most demanding applications.
Cat torque converter with lock-up clutch helps reduce torque converter losses and lowers system heat.
Maximum responsiveness with Steering and Transmission Integrated Control (STIC™).
Moves more material efficiently with improved power and control.
Durable construction withstands the toughest loading conditions and multiple lifecycles.

LONG TERM VALUE AND DURABILITY

World-class transmission for long life and consistent, smooth shifting; specifically designed for mining applications.
Advanced productivity electronic control strategy (APECS) transmission controls for optimal momentum on grades.
Positive flow control (PFC) hydraulic system helps increase efficiency, bucket feel, and responsiveness with consistent performance.
Advanced filtration system for extended performance and reliability of the hydraulic system.
Impeller clutch torque converter (ICTC) helps minimize tire spin by allowing torque to adjust to underfoot conditions.

PERFORMANCE AND PRODUCTIVITY

Superior digging, higher bucket fill factors, reduced dig times.
Improved visibility over the top of the linkage.
Operators can now monitor tire pressure during operation. Any change sending a fault code to VisionLink®, helps prevent premature tire failure.
Convenient, responsive, electro-hydraulic controls help increase operator productivity.

PERFORMANCE WITH LESS FUEL

Economy mode helps optimize engine speed control for reduced fuel consumption no matter if operating in manual throttle or throttle lock.
Flow sharing hydraulics provide full flow at reduced engine rpm.
Fully integrated electronic engine controls help make your fuel go farther.
Engine idle shutdown for less fuel used while idling.
Increased hydraulic speed and fast cycle times helps decrease idle and fuel burn, with optimal efficiency.

Purpose-built tilt and lift cylinders on the linkage help improve load control and ensure safe and long lasting operation.
Ride control acts as a shock absorber, providing the operator with a smoother ride over rough terrain.

PURPOSE-BUILT SPECIALTY MODELS - MILLYARD

Unload a typical full-length log truck in a single pass with the larger lift and tilt cylinders and a unique tilt lever to maximize linkage force. Designed with more lift capacity and 26% more tilt capacity over the standard 988.
Swing out fan radiator design for easy service in high-debris millyard applications helping to reduce maintenance and service down time. Auto reversing fan system to help dislodge debris and keep air flowing across the radiator cores.
Additional counterweight to help increase stability for improved confidence while maneuvering with full loads.
Purpose-built lift arm with lowered cross member to help increase visibility to the tips of the forks helping to increase the speed when lining up the load and reduce operator movements to see the forks.

PURPOSE-BUILT SPECIALTY MODELS - STEEL MILL

Durable and reinforced attachments for operator comfort, safety, and easy machine access.
Radiator is designed for easy cleaning and to keep material from building up.
Auto reversing fan and easy access to cooling cores help keep cab at comfortable temperature.
Equipped with extra guarding and heat protection for critical machine functions.
