System for stabilizing a track-wheel based device on a support track

A track-wheel based device for moving on a support track, the track-wheel based device comprising:

• a support-finger coupled to the track-wheel based device via a pivot point, the support-finger being rotatable about the pivot point between a first position and a second position, wherein in the first position, the support-finger is configured to sandwich the support track between the track-wheel based device and the support-finger;
• and
• a biasing member having a first end and second end, the biasing member being coupled to the at least one support-finger via the first end, the biasing member being coupled to the track-wheel based device via the second end, wherein the biasing member is configured to maintain the at least one support-finger in the first position.

A stabilizing assembly for stabilizing a track-wheel based device over a support track, the stabilizing assembly comprising:

• a support-finger configured to be coupled to the track-wheel based device via a pivot point, the support-finger being rotatable about the pivot point between a first position and a second position, wherein in the first position, the support-finger is configured to sandwich the support track between the track-wheel based device and the support-finger;
• and
• a biasing member having a first end and second end, the biasing member being configured to be coupled to the at least one support-finger via the first end, the biasing member being coupled to the track-wheel based device via the second end, wherein the biasing member is configured to maintain the at least one support-finger biased in the first position.
