PT1250 Hydraulic Puller and Tensioner

The PT1250 offers 11,240 lbf (50 kN) of pulling or tensioning capacity for power line stringing and is designed for stringing one rope or one conductor. The bull-wheel grooves on the PT1250 are made from high resistance interchangeable nylon sectors. The PT1250 features a new digital interface with automatic power management and full safety controls making it one of the most advanced pieces of conductor stringing equipment available.

Frequently Asked Questions

Condux Tesmec Puller Tensioner Basics

Condux Tesmec puller tensioners are the state-of-the-art in the transmission and distribution industry. Much of the existing equipment designs in the industry are several decades old. The dual speed mode of most Condux Tesmec equipment provides cable safety by providing different installation speeds and low and high forces, while precisely monitoring, charting and controlling the installation. Electronic controls eliminate galloping and allow smooth installation at all speeds. This provides maximum safety, especially when pulling over energized lines.

How does the PT1250 figure into Condux Tesmec’s line up?

The PT1250 puller-tensioner is one of the latest additions to the Condux Tesmec line. The PT1250 offers 11,240 lbf (50 kN) of pulling or tensioning capacity and is designed for stringing one rope or one conductor. The bull-wheel grooves on the PT1250 are made from high resistance interchangeable nylon sectors.

How do operator controls compare to other units?

The PT1250 also comes standard with the latest and most advanced controls in the industry. The new user interface features a 7-inch color display with integrated pull and speed recorder. The radio remote control provides total user machine control while integrating with the new digital user interface.

Are there any special safety features?

A negative-brake maintains line tension in the event the pull is stopped or power/hydraulic pressure is lost. No operator action is required to initiate this feature. The unit’s hydraulic rope/conductor clamp allows for fast, easy and safe reel change operations.
