The Sherman + Reilly™ Duct Dawg™ X DDHX 75/100 is an underground puller capable pulling 7,500 lb or 10,000 lb respectively. This underground unit simplifies jobsite setup with a fully articulated, self-supported 3-axis boom capable of performing a wide horizontal swing arc (greater than 50 degrees left/right), 90 degree vertical arc (up/down), 24-inch telescoping (in/out) with a sheave head that swivels approximately 60 degrees as well, allowing for approximately 10 degree adjustments within this range. The short length also makes setup easy.
Primary operational control is provided via a remote control which allows the operator complete locational flexibility. This also lowers the risk of “touch potential” when pulling in proximity to energized environments. The remote controller’s graphic system displays relevant pull information, including direction, line tension, line footage, and speed, as well as battery and connectivity strength. CANbus technology provides for accurate real time display readouts of the machine system status.
The 3-speed gearbox allows for smooth operation with potential pulling and payout speeds between 0 to 120 feet per minute and an on demand payout of up to 285 feet per minute. All on the continuous welded, heavy-duty frame, the pulling backbone is provided by hydraulically driven twin capstan 6-inch bullwheels (5 and 6 groove) with forward, reverse, and demand payout capabilities in each gear.
The control system and remote control are located in a lockable control box to prohibit unauthorized use. A custom toolbox insert organizes, secures, and protects air adapters and dies, while still providing room for sheaves and other tools.
