High Strength Aluminum Alloy Wire Rope Clips Stringing Bare Overhead Line Conductors​

Cable Grip Introduction

Come-along clamps are used for tensioning and stringing bare overhead line conductors. They are an indispensable tool for every lineman. All parts are pivot fastened. Because of its spring action, the come-along clamp locks on to the conductor even without tensile load. The different conductor materials require clamping jaws with corresponding conductor grooves.

While the cable grips used in the original cable railways were manually operated, requiring considerable skill and strength, modern cable grips tend to be automatic. Given that the cable runs at a relatively constant speed, accelerating the vehicle to match the speed of the cable presents a technical difficulty; possible methods are to apply the grip gradually, to accelerate the vehicle (e.g. by guiding wheels) prior to applying the grip, or to use a sprung linkage between the grip and the vehicle. Also, the cable needs to be able to handle friction from the grip and increased load while the vehicle is accelerating.
