The Cat^® 992 Large Wheel Loader has set the standard in its size class for more than 50 years, delivering industry-leading productivity, unparalleled reliability and long life. Today’s 992 raises the bar. Compared to the 992K, the new 992 is up to 48% more efficient and 32% more productive, thanks to higher payload for improved pass match, increases in rimpull and breakout force, and an optimized linkage design. Extended component replacement intervals plus increased filter and turbo life help reduce maintenance costs. These improvements — and many more — combine to provide significant savings over the life of the machine for the lowest owning and operating costs in the industry. With both standard and high-lift configurations, the 992 offers the ideal pass match for fleets of Cat 775, 777 and 785 trucks.

Improved access and egress, with integrated powered access system, adjustable hanging steps, 45-degree-angle wide stairs, emergency egress ladder, and full handrails on each side.
Wide walkways with non-skid surfaces and integrated lockout/tagout points designed into the service areas.
Speed limiter, which sets the maximum speeds in both forward and reverse.

OPERATOR COMFORT

50% increase in leg room and increased width by the operator’s knees compared to previous model.
Reduced vibration, low sound levels and automatic temperature controls.
Electro-hydraulic speed-sensing steering with force feedback for shift-long comfort.
Pressurized cab featuring Next Gen Seat with 9-inch travel, active cooling and heating, adjustable lumbar support, seat cushion tilt adjustment, and air-adjustable bolsters on the seat and backrest.

CONFIDENT & EMPOWERED OPERATORS

Low-effort integrated controls that make cycles smoother and faster while reducing fatigue.
Large, easy-to-read, color LED displays that provide access to the Electronic Operation & Maintenance Manual.
Operator coaching, which helps empower operators to exceed targets by measuring and providing feedback to reinforce proper operating techniques.
New Autodig Components that boost efficiency and reduce tire wear by automating critical parts of the digging cycle.
Payload Overload Prevention, which inhibits severe payloads from being raised to full truck height.

PRODUCTIVITY

Increased rated payload, which allows for a a 4-pass match to a 90.7-tonne (100-ton) truck in all applications.
Better digging thanks to 20% more breakout force compared to previous models, with no increase in cycle time; 9.5% boost in rimpull; and increased traction.
Superior loading with Cat Performance Series Buckets, which deliver easier, faster loading; increased fill factors and material retention; larger bucket volume; and better bucket and machine stability due to the payload being lower and closer to the machine.
Greater stability, thanks to an increase in static tipping load and greater tipping-to-weight ratio, which helps operators be more confident and productive.

EFFICIENCY-BOOSTING FEATURES

Tire Slip Prevention, which reduces rimpull when there is less downforce on the tire and increases rimpull when there is more downforce on the tire — providing maximum rimpull when you can use it.
Tire Set, which automatically applies a lift command at the optimal time to increase traction on the tire, allowing for an increase in usable rimpull.
Lift Stall Prevention, which automatically applies the impeller clutch when necessary to prevent hydraulic stall when lifting up through the face — keeping the lift motion continuous, without excessive use of the impeller clutch.
Positive Flow Control Hydraulic System, which boosts efficiency with concurrent pump and valve control and increases bucket feel and control to deliver consistent performance.
On-demand throttle feature that allows operators to maintain normal operation with the left pedal and implements while the 992 manages the engine speed.

SERVICEABILITY

Reduced time spent on regular maintenance procedures thanks to features such as ground-level or platform access to filters; grouped service points; swing-out doors on both sides of the engine compartment; improved access for engine and pump drive service as well as to cooling package; and automatic lubrication system that greases the linkage, hitch, steering and axle trunnion bearings.
Relocated service station that provides easy access to functions such as coolant and oil as well as level indicators; Cat battery charging connector; and indicator lights for full fuel tanks.
Standard VIMS™ monitoring system that delivers critical health and payload information, keeping performance at optimum levels and allowing advanced troubleshooting and planning to lower maintenance costs.
Improved hydraulic system filtration as well as prognostics for the implement pump and remaining useful life of the engine air filter.
Remote Flash capabilities that reduce downtime by providing immediate access to the latest software updates.

VERSATILITY

Ideal for all temperatures, with high ambient package for operation in temperatures as high as 55 degrees C / 131 degrees F; and cold-weather features such as cooling fan bypass; 120V or 240V coolant heating elements and fuel heater; 240V engine oil; and heated mirrors.
Approved for higher payloads in low to moderate digging resistance applications; increased payload intended for rehandled material in the ROM pad area or stockpile material, such as coal.
Variety of bucket options, including limestone bucket; granite buckets for use in high-abrasion production applications; heavy-duty rock buckets for applications like face loading tightly compacted pit materials or handling materials of moderate abrasion and high impact; coal buckets for light density non-abrasive materials; and iron ore buckets for extremely aggressive applications.
New Performance Series Buckets that feature extended floor, dual radius and angled side bars for fast loading; larger bottom box section for increased strength, high fill factors and good material retention; and taller side plate with a level top surface improves operator visibility to the bucket from the cab.
Cat Ground Engaging Tools (GET) that feature CapSure™ Retention Technology, which simplifies component replacement with hammerless retention for fast, easy and safe installation.

DURABILITY

New C32B engine improved for increased durability.
Use of structural castings at the high-stress locations where the lift arm and front axle mount; and improvements to the axle cutout, upper hitch design and rear trunnion mounting.
Loads efficiently transmitted by the field-proven solid steel lift arms and reinforced pin joint bores.
Powertrain improvements including 20% increase in Planned Component Replacement interval of drivetrain components; increase in axle housing size, which enabled the elimination of the brake anchor and integration of brakes into the housing; 23% increase in oscillation joint diameter, which greatly increases surface area and reduces bearing wear; and increased hardness on Output Transfer Gears (OTG).
Frame, powertrain, engine and components that all built to be rebuilt — using new, remanufactured or rebuilt parts and components — to deliver multiple lives of like-new performance at a fraction-of-new price.

TECHNOLOGY

Cat MineStar™ Terrain for loading, which provides real-time feedback on payloads and design plan progress to increases productivity and accuracy, reduce rework, enhance ore control and improve shift-to-shift operator performance.
MineStar Object Detection, which combines radar and camera systems to warn operators about light vehicles or stationary hazards within the immediate vicinity of their machines.
MineStar Health, which delivers critical event-based machine condition and operating data and includes comprehensive equipment health and asset monitoring capabilities, with a wide range of diagnostic, analytic and reporting tools.
Upgraded touchscreen information display that provides intuitive operation and easy navigation and keeps operators informed about machine systems to decrease service time.
Cat ProductLink™, which provides remote access to information on machine systems and diagnostic codes; allows you to track utilization, fuel usage and payload summaries; and gives access to machine location, service meter hours and reporting status.

SUSTAINABILITY

Designed to be more efficient and use less fuel, which reduces engine emissions and carbon footprint; Tier 4 Final engine reduces NOx and particulate matter.
Engine Idle Shutdown, which saves fuel by making it possible to avoid unnecessary idling.
Better control of fluids through use of Cat anti-drain filter housings and component ecology drains.
Retrofits and upgrades for older machines — to incorporate efficiency improvements and emission reductions, and to keep them in production longer to conserve energy and minimize the need for raw materials
