Answer: Selecting the correct roller depends on several critical factors, including the type of cable, project environment, and required load capacity. Our product line includes various types, such as straight-line rollers for open trenches, corner rollers for navigating bends, and hanging type rollers for overhead projects. We recommend considering the maximum cable weight and diameter to ensure the roller's capacity is sufficient. Our team is available to consult on specific project requirements to help you choose the best equipment for a safe and effective operation.
