General Specifications and Operational Information
**download info in .pdf format here**
Rapidly disconnects drill stems
Functions in all weather conditions
Operator does not have to leave the cabin to make drill stem changes. Operator controls wrench from the operator’s console
Wrench consistently disconnects stubborn drill stem joints, reducing drill downtime
Automatically compensates for drill stem wear
Wrench uses existing hydraulic pressure from the drill
Simple to install and low maintenance
Low initial cost.
Wrench movement is controlled by the two hydraulic cylinders and two hydraulic valves.
The wrench moves from the parked position to the drill stem and then cradles the drill stem securely.
The wrench automatically adjusts to the diameter of the drill stem, grips the stem firmly and then turns the stem.
The hydraulic system pressure range required is from 2,000 to 3,500 PSI. Pressure is taken from the existing hydraulic system of the drill.
The binding force grows with the applied torque, which in turn avoids any slippage of the wrench on the drill stem.
The wrench adjusts to compensate for drill stem wear.
The two valves are operated from the operator’s console.
Models are in service for drills using drill stems from 8 5/8” up to 10 3/4 " diameter.
