Leverage Caterpillar connected data and security principles to improve efficiencies, increase productivity and make your business more profitable.
Cat Grade Assist for excavators automates boom and stick movements for more accurate cuts with less effort. Grade Assist uses machine position sensors and operator defined depth and slope parameters to enable single-lever digging.

Cat® 2D E-fence keeps the front linkage within a predefined work area to avoid hazards like traffic. 2D E-fence uses data from position sensors to automatically stop motion when the front linkage reaches the defined boundaries.
While machines are designed to maximize operator visibility, it can be challenging to constantly monitor what is going on around them. Cat® Detect - People Detection for excavators is an intelligent vision camera system that can alert an operator when someone enters within a machine’s hazard zone.
