Abstract
A device for applying tension to a string of coiled tubing for the purpose of its insertion into or withdrawal from a wellbore. Specifically, the device is used with a wheel-type tensioner, which contacts and supports the tubing over an arc length of less than 180°. The device enhances the tractive ability of the tensioner by applying forces normal to the tubing to press it into more intimate contact with the surface of the wheel, thereby increasing the normal force and attendant frictional force between the tubing and the wheel.
