The lift stall prevention feature automatically manages rimpull in-dig to prevent hydraulic stall while lifting through the face, so the 992 spends less time in the pile.
Building on a more than half-century legacy, the new Cat 992 wheel loader sets a new standard by offering up to 32 percent greater productivity.
This new large mining loader reduces maintenance costs by as much as 10 percent and offers up to 48 percent greater payload-per-fuel efficiency than the earlier model 992K, according to the manufacturer.
Powered by the new Cat C32B engine with U.S. EPA Tier IV Final/EU Stage V and Tier II equivalent emission engine options, the new 992 meets the global industry's demand for high-production equipment with greater payloads. Powertrain design enhancements to the transmission, axles and final drive, along with the new engine, deliver a 20 percent longer interval for planned component replacement.
Offering both standard- and high-lift configurations, the 992 delivers the lowest cost-per-ton when paired with fleets of Cat 775, 777 and 785 trucks. Standard-lift payload capacities reach 25.5 tons (23.1 t) for quarry face applications and 30 tons (27.2 t) for loose material handling, while high-lift capacities reach 22.5 tons (20.4 t) and 27 tons (24.5 t) in respective applications.
More Productive, Efficient
A new Z-bar linkage optimized for performance, and improvements to rimpull and breakout force, deliver greater machine capacity and efficiency. The new 992 has demonstrated in field testing up to 48 percent greater payload-per-fuel efficiency in applications where a four-pass match to 100-ton (90.7 t) trucks was achieved, versus five passes with the 992K. The powerful and efficient 992 provides up to 9.5 percent more rimpull during digging and up to 20 percent more breakout force, increasing productivity, according to the manufacturer.
The new Cat 992 wheel loader features an on-demand throttle mode to optimize payload-per-fuel efficiency without slowing production. New standard automatic retarding controls disable the impeller clutch, enable the lockup clutch and use the implement and fan pumps retarding to slow the machine on grade. The available advanced automatic retarding controls with engine brake feature offers full control of the loader's speed on grade to maintain a desired hold speed.
Automating critical digging cycle elements, optional new autodig components further improve productivity and efficiency while reducing tire wear. To stop slippage before it happens, a tire slip prevention feature reduces rimpull before the tires are set and increases rimpull when downward force is applied to the tire. The tire set function detects pile contact and automatically lifts against the pile to set the tires and increase available traction.
The lift stall prevention feature automatically manages rimpull in-dig to prevent hydraulic stall while lifting through the face, so the 992 spends less time in the pile.
Optional new payload overload prevention allows for productivity and efficiency improvements by providing a large enough bucket to be used to achieve target pass-match across a range of material densities without the risk of overload. With the overload value fully adjustable based on the target payload, this feature can be configured to automatically stop or slow the lift function when the overload value is exceeded.
Improvements to the setback and strike plane angles, a longer bucket floor and a stronger and larger bottom section increase the bucket fill factor by 10 percent. The taller side plate with level top surface helps to improve visibility beyond the bucket edge to the material pile.
Available operator coaching empowers operators to exceed productivity targets by measuring and providing feedback to teach proper operating techniques. Among other operating techniques, this feature shows how to properly shorten travel, avoid unracking in-dig, enter the pile with a level bucket, reduce the dump height and use the kickout.
Elevated Comfort, Safety
The newly redesigned Cat 992 wheel loader cab increases visibility, offers intuitive control and incorporates next-generation technology to boost efficiency by providing easily accessible information. Its taller windshield increases the glass surface area by 25 percent, resulting in 10 percent greater visibility. Operators will appreciate the cab's 50 percent increase in legroom and more width by the knees.
Providing shift-long operating comfort, the new 992 controls feature electrohydraulic speed-sensing steering with force feedback. Two 10-in. color LED monitors display machine control and operating functions. A separate 8-in. screen provides a dedicated viewing feed of the standard rearview camera, upgradable with an optional 270-degree vision and object detection.
Low Total Cost of Ownership
Extended major component life on the new 992 and improved service access deliver up to 10 percent lower maintenance costs, according to the manufacturer.
Automatic lubrication to Z-bar linkage pins with robust guarding helps to deliver more reliable operation. A front walkaround platform simplifies cleaning of cab windows. Two large openings per machine side offer quick and convenient access to the improved cooling package, reducing cleaning time.
Improved hydraulic systems filtration and pump prognostics for the implement pump reduce machine downtime. The new loader displays the remaining useful life for the engine air filter, allowing technicians to plan ahead for machine servicing.
Offering convenient and improved access to maintenance items, the service center has been relocated to the left-hand side of the machine, along with the fuel tanks. S·O·S fluid sampling ports are safely accessed from ground level and filters are organized by type and change interval to increase maintenance efficiency.
