Mobil-trac™ Undercarriage
The Mobil-trac undercarriage provides superior durability while delivering unmatched
mobility and traction.
Mobil-trac™ Undercarriage
The Mobil-trac undercarriage combines
the flotation and traction benefits of a
crawler suspension with the mobility
and ride quality of a wheel-type paver.
Durable Mobil-trac™ Belt
The Mobil-trac system includes a
durable, high strength rubber track belt
with a thick outer cover and five
internal layers of flexible steel cable.
Large Ground Contact Area
The Mobil-trac’s ground contact area is
3020 mm (119") long and 457 mm
(18") wide. This large footprint
provides even weight distribution over
the entire length of the belt.
Two Speed Planetary Drive
A fixed displacement motor drives a
two-speed planetary providing quick
mobility around the job site.
Friction Drive
A hydraulic tensioning cylinder with an
accumulator maintains friction between
the Mobil-trac belt and the drive wheel
in order to provide drive traction.
Manual adjustment of track tension is
not required.
Rubber Coated Steel Mid-Wheels
The fully bogied undercarriage
provides low maintenance and long
life.
