Trust Your Productivity to the Inventor of Wireline Coring.
Boart Longyear is globally recognized as the leader in exploration drilling technology. From the rig and the drill string to the innovative Stage™ diamond coring bit at the bottom of the hole, our customers trust us to deliver the most advanced and complete solutions.
Our newest addition to the exploration drilling industry is the innovative, easy-to-use Quick Descent™Roller Latch™ head assembly and overshot.
Together, they employ patented technology to be safer, more productive, and to last longer than any head and overshot system today.
Surface Roller Latch™ Quick Descent™
Before Roller Latch™ technology, mechanical elements commonly known as ‘drive keys’ or ‘tangs’ were employed to drive the head assembly with the rod string in order to eliminate movement and wear between the latches and the locking coupling and between the landing shoulder and outer tube landing ring.
Underground Roller Latch™ Quick Pump-In
Drillers regularly encounter challenges when retrieving a core barrel, including partial trips, false indications, and spearhead failures. Resetting the landing indication is a costly process and increases the risk of injury.
