Abstract:
1. A pulling device, comprising: a puller body having at least one opening configured to allow a flexible line to pass therethrough; first and second gear reductions coupled with the puller body, the first and second gear reductions each including an input and an output; first and second drive motors, the first drive motor coupled to the input of the first gear reduction, and the second drive motor coupled to the input of the second gear reduction; and first and second drums, the first drum coupled to the output of the first gear reduction, and the second drum coupled to the output of the second gear reduction, the first and second drums configured to grip and pull the flexible line with rotation of the first and second drums, wherein the flexible line contacts the first drum substantially immediately after passing through the opening, wherein the pulling device is configured to be coupled with a force distributing device, the force distributing device being configured to spread at least some reaction forces of the pulling device across a surface, the force distributing device including at least two substantially perpendicular force-distributing surfaces, wherein at least one of the force-distributing surfaces of the force distributing device includes a slot therein configured to allow the flexible line to pass therethrough.
