OMAC T80.2 Hydraulic Tensioner

The OMAC T80.2 is a hydraulic tensioner for stringing conductors and fibre optic cable. It delivers a maximum tension of 80 kN and a minimum tension of 2 kN, with a top speed of 5 km/h. In pull-back mode it delivers a maximum pull of 80 kN at 1 km/h.

The machine has one pair of steel bull-wheels lined with multi-grooved nylon sectors, each Ø1500 mm with 10 grooves. It accepts conductors up to 2 x 42 mm in diameter. A version with Ø1800 mm bull-wheels is also available. A device to control low-force tensions (2–25 kN) is fitted as standard and is especially suited to fibre-optic cables.

Power comes from a water-cooled diesel engine rated at 35 hp (26 kW), with a 12 V electric plant. A heat exchanger cools the oil in the hydraulic circuit, and an auxiliary hydraulic circuit controls 1 or 2 reel-stands (not independent).

The operator works from a control panel with a built-in DEG 4.0 electronic instrument, which has a 7″ graphic colour display and a USB port. The T80.2 uses a maintenance-free load cell reading system and has an electronic instrument by-pass. It also has a self-recovery device for sagging operations, a negative hydraulic safety brake, a manual clamp for 2 conductors, and two back fix conductor-drivers with nylon rollers.

As standard, the T80.2 sits on a rigid-axle chassis with a manual brake and a detachable drawbar for low-speed towing on the job site. It has a mechanical front plough and back stabilisers, attachments for anchoring and lifting, and a grounding connection point. The machine measures 3.85 m long, 2.10 m wide and 2.20 m high, and weighs 3500 kg without rope.
