Here is a complete system for drilling long holes and boring raises as large as 14 ft (4.3 m) in diameter and up to 2,200 ft (670 m) in length. System includes an Electrohydraulic Power Pack with integral controls, a Remote Control Station and tools to make or break threaded pipe connections.
Infinitely variable speed and constant torque of the hydraulic drive enable you to adjust rotary speed to exactly match your drilling conditions. Shifting is done hydraulically for a smooth change into either the high-speed range for pilot hole drilling or the low-speed range for reaming.
The tandem hydraulic cylinder mechanism is the basis for the low profile design which allows the machine to be set up for vertical drilling in a station height of only 17 ft (5 m).
