Purpose
A double break out clamp mounted at the base section of a drill mast means that the breaking of casing or rod connections is rapid, safe, sure and ergonomically friendly.

Application
The casing is pulled up in such a way that the bottom and top clamp can clamp the bottom and top casing. Then the cylinder that rotates the upper casing is operated to break the connection. The top clamp is loosened to allow the drill motor to further untwist the top casing. The top clamp is closed again which allows breaking and completely untwisting the drill head spindle from the top casing. Then the top casing is lifted and stacked by hand or with a manipulator. The drill head is lowered on the bottom casing (which is still clamped in the lower clamp) and twisted in. The lower clamp is loosened and the casing is pulled up. This sequence is repeated until all casing sections or rods have been removed.

Quality
These are not just double break out clamps! You will not find construction errors like welds on hydraulic cylinders. This are heavy duty clamps equipped with oversized bearings and hydraulic parts. The construction is based on many years of experience and for many years of intensive use. All parts are exchangeable. Grip bit inserts can be field exchanged within minutes. |

In short
• All sliding surfaces are tempered and are in addition fitted with lubrication points
• Rotation is perfectly guided by a double thrust block
• Top and bottom clamps can be mounted at various distances to comply with any casing thread type
• The unscrewing part can be separated from the clamping part
• All components are separately replaceable and in stock
• Grip bit inserts (hardened at 58 Hrc) replaceable in only a few minutes
• Clamping and untwisting parts can be done independently |
