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 Lift Assist is an excavator safety feature that quickly calculates the actual load you are lifting and compares it to the rated load the excavator is capable of handling. Visual and auditory alerts tell you if you are within safe working range or need to take action to avoid tipping.
