  • 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.


  • 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.


  • 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.
