Abstract:
Implementations described herein include a hoisting device and method for handling, coupling and recovery of tubular members such as drill string components. The hoisting device has a self-energizing gripping means configured to releasably engage a drill string component. In one aspect, the self-energizing gripping means can be operable to increase at least one of a radial biasing force and a contact friction force applied to a drill string component, causing the gripping means to increase the overall gripping force applied to the component with minimal effort exerted by a hoisting device operator.
