The John Henry LTS – Excavator Mounted Rock Drill
The JH LTS consists of the full capacity 12′ heavy duty feedshell with stainless steel slide rails on the highly reputable Komatsu PC138USLC-10 excavator platform. The JH LTS is capable of horizontal and vertical drilling.
The following components are included:
LTS
Limited Tail Swing allows for “over the side” operation on narrow job sites and compact work areas.
Feed
12′ Feedshell with stainless steel slide rails capable of drilling with 38mm, 45mm, or 51mm drill steel creating holes ranging from 2″ to 6″ in diameter.
Drifter
“Dry Fire” model RD3 hydraulic percussion drifter.
Compressor
Portable Air Compressor required
Hydraulic System
The excavator is the primary source of power for all hydraulic John Henry drill functions. A dependable pilot operated hydraulic system (not an electric system) is used to direct the flow of oil to the drill package. Standard excavator functions and controls are not affected. Heavy-duty steel tubing is used in combination with hydraulic hosing for all hydraulic connections.
Controls
The control panel, located in the operators cab, contains pilot controls for tilt, rotation, air, feed, and impact. Rotation speed, feed pressure, air volume, and water suppression are all fully adjustable from this panel. Feed pressure and air pressure gauges are located here as well.
Dust Control
A water suppression system is provided. A hydraulically driven duplex pump transfers water from a stainless steel 60-gallon tank into the flushing air stream. An optional Dry Type 900 CFM dust collection system is available upon request.
Accessories
Allows operator to add (1) 16’ rod from cab allowing total drilling depth of 35’.
The Optional dust collection system can be added when air born dust is regulated or the standard water dust control is not an option for the project. The vacuum system captures the dust and distributes it gently tot he ground to minimize air born particles.
