Elevator 86
Elevator 86 :
A heavy, hinged clamp in the derrick that is attached to the hook and traveling block by bail-like arms. The elevators are used for lifting drill pipe, casing, and tubing and lowering them into the hole. In hoisting a joint of drill pipe, the elevators are latched on to the pipe just below the tool joint (coupling), which prevents the pipe from slipping through the elevators
