Ezy Lock Overshot
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.
• 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
