<p>A lightweight, manually operable cable bender particularly adapted for forming expansion loops in relatively stiff cable, such as coaxial cable, during aerial cable stringing operations. The bender includes a lightweight plate member forming the main frame which carries a pair of bending shoes on its outer ends and an auxiliary frame carrying intermediate bending shoes, with the main and auxiliary frames interconnected by a rack and pinion to draw the shoes carried by the frames towards each other and form a loop in a straight piece of cable engaged by the shoes. The cable bender can be constructed to handle a single cable at a time or two or more cables simultaneously. In either case the bender permits the formation of loops at any point along the cable, eliminating the necessity of having access to a cable end in order to form a loop therein.</p> |
