Overshots

Overshots are a key component of Hole Products wireline coring systems. To retrieve the core sample, the overshot is lowered into the hole on a wire cable until it comes in contact with the spearhead point on the head assembly. Positive latching lifting dogs securely attach, and the inner tube assembly is pulled from the hole to retrieve the core. Once the core laden inner tube is hoisted above the top of the drill rods, the safety lock pin can be inserted through the overshot head and under the spearhead point. This will allow the operator to safely hoist and remove the core sample from the inner tube.
