Product Description
Nq Overshot Assembly

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 point.
Threaded connection between jar staff and overshot head.
High strength alloy steel jar staff with increased diameter and fail safe stop.

Reaming shells and casing/rod shoes
Wireline drill rods,
Core barrels & overshot assemblies
Hoist plug and water swivels
Recovery tapes and Casing cutters
Drill string subs and adaptors
Overshot is a necessary device in wireline drilling. Once the inner tube is full of core, the overshot is lowered to the bottom of the hole, and its heavy-duty lifting dogs grab a secure hold at the top of the inner tube assembly. It saves the time to connect and dismantle the rod string when the core is retrieved.
