New Cat 992 Wheel Loader

The new 106-tonne Cat 992 Wheel Loader offers up to 32% greater productivity than its predecessor, the 922K. The large mining loader reduces maintenance costs by as much as 10% and offers up to 48% greater payload-per-fuel efficiency than the earlier model, too.

Powered by the new 814-823hp Cat C32B engine with US EPA Tier 4 Final/EU Stage 5 and Tier 2 equivalent emission engine options, Catepillar says powertrain design enhancements to the transmission, axles and final drive, along with the new engine, deliver a 20% 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 23.1 tonnes (25.5 tons) for quarry face applications and 27.2 tonnes (30 tons) for loose material handling, while high-lift capacities reach 20.4 tonnes (22.5 tons) and 24.5 tonnes (27 tons) in respective applications.

A new Z-bar linkage optimised 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% greater payload-per-fuel efficiency in applications where a four-pass match to 90.7 tonne (100-ton) trucks was achieved, versus five passes with the 992K. The powerful and efficient 992 provides up to 9.5% more rimpull during digging and up to 20% more breakout force, increasing productivity.

The new Cat 992 Wheel Loader features an on-demand throttle mode to optimise payload-per-fuel efficiency without slowing production. New standard automatic retarding controls disable the impeller clutch, enable the lock-up 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.

Meanwhile, 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%. The taller side plate with level top surface helps to improve visibility beyond the bucket edge to the material pile.

The new Cat 992 Wheel Loader cab’s taller windshield increases the glass surface area by 25%, resulting in 10% greater visibility. There’s 50% more legroom too. The new 992 controls feature electrohydraulic speed-sensing steering with force feedback. Two 10-inch colour LED monitors display machine control and operating functions. A separate 8-inch screen provides a dedicated viewing feed of the standard rear-view camera, upgradable with an optional 270-degree vision and object detection.

Extended major component life on the new 992 and improved service access deliver up to 10% lower maintenance costs. 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.
