  • Managing tensile forces in a cable
    Patent number: 8770272
    Abstract: A well servicing system includes a frame adapted to mount to a pipe handling system that includes a hanger adapted to guide a load coupled to a cable towards a wellhead, where the load exerts at least a portion of a tensile force on the cable; and a winch including a drum and a brake. The brake is adapted to control rotational motion of the drum to spool a portion of the cable over the drum and set the drum to substantially prevent rotational motion of the drum. The well servicing system also includes a hydraulic piston-cylinder coupled to a sheave. The piston is adapted to stroke into or out of the cylinder when the tensile force exceeds a desired load when the drum is set to substantially prevent rotational motion to spool the cable from the drum.
