Pressurized hose embedded into cross pieces; the cross pieces are
covered with rubber, with felt on the bottom. Dollies with
specialized wheels ride on the pressurized hose once the pieces
have
been joined. The wheels fit the hose in cross section, but also
have
a rubber rim on each side
that will roll on level surfaces.
The track is rolled out through the house when moving. It is then
pressurized with air. Appropriate 90 and 45 degree sections are
included, and connect with fittings and O-rings. The track goes
out
of
an exterior door and up the ramp to the truck.
