Full box-section frame has been redesigned for maximum strength and minimum weight.
Box-shaped tower is designed for improved resistance to twisting for maximum strength.
Upper and lower hitch-pins pivot on double-tapered roller bearings.
Spread-hitch design increased the spread 26 percent to help square up the frame and provide increased clearance for access to the hitch and hydraulic lines.
Steering cylinder mounts are located on the axle pads providing efficient transfer of steering loads to the axle.
Fabricated box boom replaces the traditional steel plate lift arms found on wheel loaders.
Box-section design of the fabricated boom has more torsional strength than the previous Z-bar design.
The turbocharged and aftercooled 3456 Electronic Unit Injection Diesel Engine delivers 10 percent more power and 24 percent improvement in torque rise.
Separate engine cooling system isolates the radiator and fan from the engine compartment for more efficient cooling and allows for a sloped hood for increased viewing.
Electronically controlled Caterpillar planetary, power shift transmission features perimeter-mounted, large diameter clutch packs that control inertia for smooth shifting and increased component life.
Impeller Clutch Torque Converter (ICTC) combined with the Rimpull Control System (RCS) allows the operator maximum flexibility in modulating rimpull.
Heavy-duty axles feature optional axle oil coolers, permanently lubed universal joints and stronger axle components in both the differentials and final drives for increased performance, serviceability and durability.
Axle-shaft, oil disk brakes are adjustment free, fully hydraulic and completely sealed. Disc face grooves provide cooling, even when brakes are applied, for a long, fade-resistant service life.
Revolutionary electro-hydraulic control system increases hydraulic efficiency and enhances operator comfort through low-effort finger tip controls. Caterpillar's XT-3 and XT-5 hoses and reliable components help reduce the risk of leaks and blown lines, helping protect the environment.
Lift and tilt system consists of larger bore lift and tilt cylinders and a two position main hydraulic pump contributing to increased performance and serviceability.
Load sensing steering with STIC control system integrates steering and transmission into a single controller.
Case drain filtration is an optional attachment included throughout the hydraulic system to protect against contamination and provide easy access for service. A total of three filters protect the main hydraulic, steering, and fan pumps.
The demand fan is a speed controlled, hydraulic fan that provides maximum cooling efficiency by directing the appropriate amount of power through the fan system based on ambient conditions.
Advanced electronics play a major role in the operation of the 988G. Productivity improvements, enhanced serviceability, increased operator efficiency and lower costs are direct benefits of the 988G advanced electronics.
STIC control system combines gear selection and steering into one control lever that requires less effort and provides smooth shifting.
The left pedal operates impeller clutch torque converter.
Cat Comfort Seat replaces the previous Contour Series Seat.
Floor mounted Electro-Hydraulic Controls and armrests provide low effort, finger tip control for enhanced comfort and stability.
Electronic Monitoring System II (EMS II) display system provides information on the machine's major components and system.
Throttle Lock allows operator to preset the engine speed for a variety of applications, resulting in faster cycle times and increased productivity.
The Rimpull Control System (RCS) Switch turns RCS on and off.
Rimpull Control System (RCS) has four factory preset reduced rimpull settings.
Kickout Positioner Control is one of the many in-cab electronic features designed to enhance productivity.
The Optional Ride Control Switch turns Ride Control to off or automatic position.
Autoshift feature allows the operator to set the maximum gear into which the transmission will be allowed to shift. This feature allows additional comfort and focus on the job. The switch also offers a manual position for operator controlled shifting.
Optional lock-up clutch torque converter switch activates lock-up clutch for direct drive efficiency.
Loose material operating mode tailors hydraulics to provide maximum loose material loading efficiency.
Front and rear window wiper/washers are within easy reach to maintain a clear field of vision.
Improved viewing area with bonded front windshield eliminates distracting metal frames for excellent bucket and work site visibility.
Electro-hydraulic lock-out switch disables hydraulic controls.
The 988G has several buckets available that may be configured for a variety of impact and abrasive conditions.
Spade-Edge Rock Buckets with bolt-on segments are available.
Straight-Edge Buckets are available in Straight-edge Rock and General Purpose configurations. The Straight-edge Rock features shouldered, double strap adapters and accepts two sets of side bar protectors, bolt-on segments and tips. The General Purpose Bucket is available with bolt-on cutting edge, bolt-on adapters, or bolt-on adapters with segments.
Heavy-Duty Quarry Bucket is available and is recommended for use in face loading where moderate abrasion and high impact is encountered.
High Abrasion Bucket is available and is recommended for use in face loading where high abrasion and moderate impact is encountered.
The 988G offers a variety of bucket types and available Ground Engaging Tool configurations to properly configure the machine based on material density, impact and abrasion.
