  • Cat 2D E-fence for Excavators

    Cat 2D E-fence is an excavator safety feature that keeps the front linkage within a predefined work area to avoid hazards such as traffic. 2D E-fence uses data from position sensors to automatically stop motion when the front linkage reaches the operator defined boundaries.

  • Cat Lift Assist for Excavators

    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.
