About the 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 pair. 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 and in forward drive for ease of bullwheel reeving. The T-7212 is designed to work with the CRS-96/67 and CRS-108/83 reel stands by connecting any two of the four available external hydraulic connections either on the front or rear of the T-7212. When the CRS-96/67 or CRS-108/83 is connected to the T-7212, the operator can control hold back tension from inside the T-7212’s Safe-Zone® Cab.
The T-7212 features a Safe-Zone® Cab providing ultimate safety and comfort for the operator. The Safe-Zone® Cab employs a polycarbonate front window for maximum visibility while providing superior protection against impact. The cab includes climate control, a fully adjustable ergonomic seat, and all required electronic controls and gauges. The Safe-Zone® Cab is designed to reduce operator fatigue, and provide an “off -ground” envelope for greatly reducing the risk of “touch potential” in energized environments.
The T-7212 off ers either a heavy-duty 5th wheel king pin hitch or a pintle eye hitch option for maximum vehicle towing compatibility, has PLC machine controll 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.
