Hydraulic feed and retract system provides 19,600 lbs. [8,891 kg] of retract force and 13,650 lbs. [6,192 kg] of down pressure.
The 68 inch [173 cm] stroke, hydraulic vertical drive system has no chains or cables which can stretch. It gives you precise control of force on the drilling tools.
Rugged mechanical rotary drive with up to 4,815 foot pounds [6,528 Nm] of torque.
Several torque and rotation speed combinations are available, including a high-speed rotary drive that gives you up to 700 rpm. The four speed transmission is connected to the drill engine through a heavy-duty clutch. With four forward gears and one reverse, there’s a rotation speed and torque combination available for just about any situation. The mechanical rotary drive also gives you a good feel for changes in soil and drilling conditions down the hole. It allows you to sense the need to adjust feed pressure and rotational torque. A torque limiting clutch, which is adjustable, provides protection against shock overload.
All drilling and set-up controls are logically arranged on a control panel located at the drillers station. A lock-out position for the clutch lever helps prevent accidental engagement.
Our emergency spindle brake can stop rotation in less than a revolution. This system is activated by two conveniently located push button switches, as well as by strategically located multi-directional wobble switches.
