Abstract: Disclosed is an actuator device for remotely engaging, in fail-safe fashion, the slip segments on a slip-type elevator used in connection with a drill pipe, casing, or other object being lowered into or pulled out an oil, gas, geothermal, water, mining or other subsurface well. An actuator drive mechanism is provided and capable of extending a cylinder to engage the top surface of a slip segment or slip setting plate to cause the slips to be pushed into gripping engagement against the outer surface of the drill pipe, casing, or other object. The slips may be equipped with retention springs to move the slips back to their non-engaged positions when the actuator drive is disengaged or to urge continued engagement. The actuator drive cylinder can also be directly attached to the slips or slip setting plate and is capable of moving the slips into and out of their engaged position.
