Wireline Fishing Tools Ezy Lock Overshot Complete Assembly bq nq hq pq
Overshot is a necessary device in wireline drilling. It's dropped on a cable and directly couples onto and lift up the inner tube assembly, eliminating the need to couple and uncouple the rod string each time the core is retrieved.
Ezy Lock Overshot is a modified product based on compact overshot. It protects against accidental release of the core barrel. This is ideal for suface application when hoisting above ground.
Overshot is a key component of wire-line 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.
Features:
• Ezy Lock Sleeve provides a quick, one-handed rotation of the sleeve to lock the lifting dogs.
• Quick Release Safety Pin locks the overshot head to the spearhead point.
