Abstract
The invention relates to a method for moving cable into or out of installations. In one embodiment there is provided method for moving cable into or out of underground and overhead installations, comprising: providing a mobile platform having a cable guiding assembly thereon, including cable pulling wheel means; positioning sheave means proximate the location of said cable installation; and movably presenting said sheave means using extensible means for providing a first straight path between said installation and said sheave, and a second straight path from said sheave to said wheel; said extensible means including first hydraulic means having a fixed reference for movement in an extension direction and a retraction direction; second hydraulic means moveable in both of said directions; and means for actuating said first and second hydraulic means in series, whereby actuation in said extension direction sequentially moves said first and second hydraulic means, and actuation in said retraction direction reverses the sequential order of movement of said two hydraulic means.
