It's a light weight energy-saving drifter rig for 44-64 mm (1-3/4 - 2-1/2") holes.
Don't let the small size of this husky little drilling rig fool you. It's a fully-mechanized, self-propelled Crawlair drill that does all the heavy work for you. It trams easily from hole to hole at the touch of a throttle, towing a portable air
compresor. The drill tower is quickly positioned by effortless hydraulic cylinder operation.
With the YD-90 drifter, it handles a 3048 mm (10') rod change, with 32 mm (1.25") rods, threaded bits and couplings, to depths of 12 m (40') at maximum efficiency.
Simple, safe one-man operation. All tramming and positioning controls are located at the rear of the machine for easy operation. Drilling controls can be mounted on the tower or at the side of the machine for convenience in either deep-hole or single-pass drilling.
Rugged crawler construction. With two independently-controlled 7-hp tramming-air motors, it can climb a 35° grade.
Track oscillation.
Heavy steel main frame has walking-beam track to tilt up or down to match ground irregularities.
More powerful hydraulics.
A 3-hp hydraulic pump motor assures faster positioning.
Air and oil gages.
Continuous indication of air pressure and lubricator oil level take the guesswork out of
drill operation.
Independent rotation drifter. The YD-90 air drifter has ample power for drilling holes to 64 mm (2-1/2") in diameter. Integral air motor drive provides independent rotation with infinitely variable speed control.
Uses little air.
With a P425 SpiroFlo Compressor, there's plenty of air to
operate the drill, rig and optional dry dust collector.
It's a low-noise deep-drilling downhole rig for 85-90 mm (3-3/8-3-1/2") holes.
Drills faster on deep holes because penetration rate doesn't fall off with each rod added to the string.
Uses less air because the same air does double duty, powering the drill and then cleaning the hole.
Externds rod life because no impact forces are transmitted through the drill rod.
Stop-action plunger automatically stops the hammer action whenever the drill is raised.
