Tesmec’s PT1250 hydraulic puller-tensioner provides features to improve productivity and efficiency whilst also improving safety for operators. Advanced improvements to machine operating systems such as a negative self-acting hydraulic brake, an integrated hydraulic dynamometer, hydraulic cooling system and advanced user controls.

The PT1250 offers 50kN 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 sections. A new digital remote interface with automatic power management and full safety controls offers the user better safety features and increased control.
