Abstract
A pulling apparatus includes a frame having a securing stirrup for securing a beam. The beam is provided at one end with a return pulley. Due to the structure of the securing stirrup, the tractive forces are transferred completely to the beam and the frame so that the means for securing the apparatus to the ground can be minimized. Such a design easily allows the beam to be set at an angle when the pipe is off center. The apparatus may also be easily placed in a cable chamber for operation.
