Specifications include, but are not limited to: : Drill Machine, Mounted , All-Terrain Carrier, auger, core, rotary type.
Acceptable Brands/Models: CME-55/300, Acker Rebel, Diedrich D-50 or approved equal.
ALL SPECIFICATIONS ARE CONSIDERED MINIMUM UNLESS OTHERWISE NOTED
ITEM: One combination auger, core, rotary type boring and subsurface exploration drilling
machine built into a specially designed remote-controlled high flotation rubber track carrier.
INTENT: These specifications describe salient features that shall be required in a combination
auger-core-rotary type track carrier mounted drilling unit. The unit shall be completely
assembled and ready for operation when delivered.
PURPOSE: This equipment shall be used for soil sampling, foundation testing, monitoring well
installation and subsurface exploration work. The drill machine shall be capable of performing
auger borings in unconsolidated formations with conventional flight or hollow- stem augers.
The drill shall have the capability of productively using currently popular geoexploration
methods and techniques that include shelby tube or continuous tube sampling and standard
penetration testing. The drill shall be capable of coring or rotary drilling applications. The unit
shall be self-contained with rough terrain capabilities allowing access to off-road sites.
GENERAL SPECIFICATIONS: The drill unit shall be an integral part of a track carrier having
a single engine power source. The power shall be appropriately directed to the carrier,
hydraulic system and mechanically or hydraulically driven drill head. A hydraulically actuated
folding upright drill frame with twin hydraulic feed cylinders shall be supplied. The drill and
carrier shall have been in production for at least 2 years and shall be manufactured by one
supplier to insure one-source parts responsibility. The track carrier and drill shall meet the
TRACK CARRIER: The carrier shall have a rugged structural steel frame designed to resist
bending and twisting when drilling or traversing rough terrain. The following specifications shall
1- Tracks are driven by individual high efficiency two-speed hydraulic motors coupled to
heavy-duty direct drive planetaries.
2- Brakes shall be coupled to the planetaries that are static parking type, spring appliedpressure released.
3- Steel drive sprockets shall be furnished for driving the tracks.
4- Two continuous track belts shall be furnished (18” min each).
5- The tracks shall be adjusted for tension and supported at the front by steel idler
sprockets. Track tension and shock cushioning shall be controlled automatically by the
hydraulic system and gas filled accumulators or adjustable by grease fittings.
