What key features should I look for when choosing a hydraulic puller-tensioner for overhead line stringing?
2025-08-12When selecting a hydraulic puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner, several features are critical for ensuring safety, efficiency, and conductor integrity. At Ningbo Changshi, our hydraulic puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners incorporate these essential features:
-
Infinitely Variable Speed Control: This allows for precise adjustments during the stringing process, preventing sudden jerks that could damage the conductor.
-
Constant-Tension Control: This feature automatically adjusts the pulling force to maintain a steady tension, which is crucial for achieving the correct sag without overstressing the conductor.
-
Safety Brake System: A spring-applied, hydraulic-released brake should engage automatically in case of a hydraulic failure, ensuring the conductor remains securely in place.
-
Digital Control System: Modern machines include a digital interface to monitor and record parameters like pulling force, speed, and distance, which is vital for quality control and documentation.
-
Durable Bullwheels: The bullwheels should be lined with a wear-resistant material, such as MC nylon, to protect the conductor from damage during the pull.
