Atlas Copco CT 20
Mast and feed frame
Christensen masts are exceedingly robust, carrying the full weight of the drillstring with capacity to spare. The integrated feed frame is 1.8 or 3.5 m long. With the possibility of using rods up to 6 / 9 m in length, high productive rod tripping is achieved. All rigs are equiped with a easy to use rod positioner.
Placed at the base of the feed frame, the rod holder uses the latest in gas spring technology. A gas cartridge ensures high clamping force while the machine’s hydraulics open the holder. This safety measure means the rod is always clamped in place when the drilling rig is shutdown. This extremely reliable holder has a seal life of 1 000 000 cycles and is easily serviced or replaced. For extra safety, the gas pressure can be monitored from the rig’s control panel. Furthermore, as it features fewer parts than competing systems, you’re looking at a lot less maintenance.
