Abstract
An active track-chain sag management system for usage in conjunction with crawler vehicles having tracked undercarriages includes a movable track-engaging member positioned for physical engagement into a track-chain of the tracked undercarriage, an electric drive assembly controllable to adjust a track-tensioning position of the movable track-engaging member relative to the track-chain, and a controller operatively coupled to the electric drive assembly. The controller is configured to command the electric drive assembly to repeatedly adjust the track-chain sag of the track-chain by varying the track-tensioning position of the movable track-engaging member during operation of the tracked undercarriage.
