Building on a more than half-century legacy that includes the best-selling large mining loader model of all time, the new Cat 992 wheel loader sets a new standard by offering up to 32% greater productivity. The new large mining loader reduces maintenance costs by as much as 10% and offers up to 48% greater payload-per-fuel efficiency than the earlier 992K model.
Powered by the new Cat C32B engine with U.S. EPA Tier 4 Final/EU Stage V and Tier 2 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% longer interval for planned component replacement.
Offering both standard- and high-lift configurations, the 992 is said to deliver the lowest cost-per-ton when paired with fleets of Cat 775, 777 and 785 trucks. Standard-lift payload capacities reach 23,1 tonnes for quarry face applications and 27,2 tonnes for loose material handling, while high-lift capacities reach 20,4 tonnes and 24,5 tonnes 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 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 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 tyre wear. To stop slippage before it happens, a tyre slip prevention feature reduces rimpull before the tyres are set and increases rimpull when downward force is applied to the tyre. The 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%. 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.
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.
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 centre has been relocated to the left-hand side of the machine, along with the fuel tanks. S∙O∙SSM fluid sampling ports are safely accessed from ground level and filters are organised by type and change interval to increase maintenance efficiency.
