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.
Features:
1.Ezy Lock Sleeve provides a quick, one-handed rotation of the sleeve to lock the lifting dogs.
2.Quick Release Safety Pin locks the overshot head to the spearhead point.
3.Threaded connection between jar staff and overshot head.
4.High strength alloy steel jar staff with increased diameter and fail safe stop.
