2025 Caterpillar Large Wheel Loaders 988

An industry leader—made better

The Cat® 988 Wheel Loader helps you move more material in less time, at a low cost per ton, for a fast return on your investment. This machine offers significant fuel savings with durability to achieve multiple lifecycles.

BenefitsBETTER FUEL EFFICIENCY

Utilizing Economy Mode helps save on fuel all while maintaining productivity

EASIER MAINTENANCE

Make regular maintenance more convenient with grouped service points

MORE PRODUCTIVITY

Deliver more productivity in most truck loading applications while using performance series buckets with increased capacities

Features may include:

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™).
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.
Safety First
  • Achieve precise positioning for easy loading in tight areas with 43 degrees of steering articulation.
  • Precise machine control by load-sensing hydraulic steering system.
  • Reduced stairway angles and standard stairway lighting provide reduced risk of slips, trips, and falls due to better visbility of the steps and stairway.
Save On Service And Maintenance
  • Grouped service points provide easy access to critical daily service checks.
  • Swing-out engine compartment service doors.
  • Reduced waste with maintenance-free batteries.
Operator Comfort And Control
  • World-class operator comfort and ergonomics.
  • Cat Premium Plus seat with standard features including leather finish, forced air heating and cooling, two-way thigh adjustment, power lumbar and back bolster adjustment, and dynamic end dampening to provide total comfort throughout the workday.
  • Easy-to-reach levers and seat-mounted implement pod to help reduce fatigue.
  • Ergonomic switch placement and displays with LED indicators.
  • Two-position rocker switch activates the electro-hydraulic parking brake.
