T450GT - Schramm Inc.

T450GT
BUILT FOR HIGH PRODUCTION GEOTHERMAL PROJECTS.
The track mounted T450GT is the drilling contractor’s rig of choice
for geothermal and water well applications where site conditions pose
challenges to traditional truck mounted designs. It is compact, light
weight and highly maneuverable.
When combined with Schramm’s patent pending Casing Rotator option,
the driller can now place casing and drill pipe simultaneously without
stopping to change equipment set up. The rotator itself is in a fixed
position and acts as the table of the rig. The mast slides up and down
to provide the feed for the rotator. A tilt–out top head is used for pipe
handling with the rotator. A diverter system discharges cuttings into an
onboard cyclone system.
Once casing placement is completed, drilling can continue utilizing an
onboard pipe carousel and other time proven features that are included
with standard T450GT rigs.
