Caterpillar Hystat Response Control System

May 2010 Vol. 65 No. 5

Recognizing that the operating skill of workers using small loaders on typical jobsites ranges from the novice to the expert, Caterpillar has developed a new control feature that allows each operator to run a Cat C-Series Skid-Steer, Multi-Terrain or Compact-Track Loader safely, productively and comfortably.

The new Hystat Response Control System (HRCS) uses software that permits the loader's hydrostatic drive/steer system to be adjusted to one of three response rates—standard, intermediate or maximum—to determine how rapidly the machine accelerates/decelerates and how quickly it responds to steering commands.

The HRCS standard setting provides acceleration/deceleration rates that feel smooth and controlled, as does steering response. In the intermediate setting, the machine will start and stop more quickly, and steering-response lag is diminished. When operated in the maximum setting, the loader will accelerate aggressively in forward, will stop abruptly and will respond instantaneously to steering commands. catrequests@cat.com
