Long-span crossings present unique challenges requiring precision and specialized techniques. Best practices that our equipment supports include:

• Pilot Wire Installation: Often, a light pilot rope is first installed using a drone or a pilot helicopter. This rope is then used to pull in progressively larger pulling ropes, and finally the conductor.

• Sag and Tension Monitoring: Utilizing a dynamometer and sag scopes (or modern digital GPS-based systems) is critical. Our hydraulic pullers provide real-time tension readouts to ensure the conductor is not over-stressed.

• Use of Multiple OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners/Brakes: For exceptionally long or heavy conductors, a multi-reel tensioning system or braking systems on the pulling side might be employed to manage the immense forces involved.

• Communication: Clear and constant communication between the puller operator, OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner operator, and spotters along the span is paramount for safety and success.

Our high-capacity pullers (8 tons, 10 tons, and higher) and multi-conductor tensioners are specifically designed to provide the power and control needed for these demanding crossing projects.
