Bullwheel Tensioner – T-7212

PRODUCT #T-7212

The Sherman + Reilly Revolution Series T-7212 is a bullwheel tensioner built with two pairs of 72 in. 5-groove bullwheels (4 total) and a max tensioning capacity of 12,000 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-7212 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-7212 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-7212 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, also reducing the risk of “touch potential” in energized environments.

The T-7212 is mounted on a 5th wheel trailer, 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-7212 can be operated in a pullback mode for easy rewinding of unused conductor and in forward drive for ease of bullwheel reeving.
