Professional Answer: A bridge type cable laying roller is an essential piece of equipment designed to facilitate the safe and efficient installation of new cables by allowing them to pass over existing ones or other obstacles within a trench or duct. Unlike standard straight-line rollers, our bridge rollers are specifically engineered with a robust frame and hoops that elevate the new cable, creating a protective "bridge" over the pre-existing infrastructure. This is critical for projects involving complex underground utility networks or when working in narrow, confined areas where space is a premium. Using a bridge roller is the best practice to prevent mechanical damage, such as crushing, twisting, or sheath fracture, to both the new cable being installed and the existing lines below.
