Bullwheel Tensioner – T-2608

Bullwheel Tensioner – T-2608


The Sherman + Reilly Revolution Series T-2608 is a bullwheel tensioner built with two pairs of 60 in. 5-groove bullwheels (4 total) and a max tensioning capacity of 8,000 lbs. per sub-conductor or bullwheel. Each bullwheel has its own planetary gearbox and hydraulic motor with spring-applied hydraulic release brake. A precision, microprocessor-controlled motor drive enables inching, even under maximum load.

The T-2608 includes an Automatic Tensioning System which maintains an operator set tension. The automatic bullwheel synchronization system maintains equal sag of all conductors, while recording/displaying tension and distance, and permitting manual override. In addition to tensioning mode, the T-2608 can operate in a pull-drive mode for easy rewinding of unused conductor.

With state of the art design to ensure operator safety, the T-2608 features a Safe Zone Cab™. This enclosure is designed to keep an operator off the ground while the equipment is in use. Built with a fully adjustable, ergonomic seat and a full set of electronic controls and gauges. The Safe Zone™ Cab is designed to reduce operator fatigue thereby reducing errors and injuries in the field. It also reduces the risk of “touch potential” in energized environments.

The T-2608 has PLC machine control with CAN-bus technology, uses a removable/replaceable memory card to store all relevant stringing data, self-diagnostic system for all hydraulic circuits, and a PTO for reel stand control. In addition to tensioning mode, the T-2608 can be operated in a pull-back mode for easy rewinding of unused conductor and in forward drive for ease of bullwheel reeving.

The T-2608 is also available in a 5th wheel configuration.
