Remotely operated placement equipment
First Claim
1. A remotely operated track vehicle comprising:
- a lightweight frame having a deck portion and first and second track guiding portions;
a drive drum located at one end of each said track guiding portions;
first and second electric motors connected each to one of said drive drums;
first and second track means each encircling and operatively associated with one of said drive drums and one of said track guiding portions; and
an obstacle hook pivotally mounted on said deck portion, said obstacle hook being oriented forward of the vehicle and located above the ground so that the bottom portion of said obstacle hook will ride up onto the surface of an obstacle in a camming action, said pivot point being above the level of said track means and a camming surface extending downwardly at an acute angle from said pivot point toward said track means to permit the track means to engage the obstacle to move said vehicle over the obstacle as said vehicle is moved forward.

Abstract
The present invention relates to a track vehicle. The vehicle is comprised of a lightweight frame having a platform or deck portion and first and second track guiding portions. Drive drums are provided, located at one end of each of the track guiding portions. First and second electric motors are connected, via gear reducers, each to one of the drive drums. Idler rollers are located at the other end of each of the track guiding portions. First and second tracks are provided, each encircling and operatively associated with one of the drive drums, one of the track guiding portions and one of the idler drums. Each of the track guiding portions has a bottom portion with each bottom portion having a longitudinally oriented strip of low friction material fastened thereto to provide a sliding surface for each of the tracks when the vehicle is in motion. In another embodiment of the invention the deck portion and track guiding portions are blow-formed from sheet plastics material. When the plastic embodiment is manufactured the longitudinally oriented strips are eliminated and the track runs directly on the plastic surface of the track guiding portions. Further, in the plastic embodiment the idler drums are eliminated and the tracks merely slide over rounded ends of the track guiding portion.
