The DPT-50B is a heavy-duty drum puller designed for distribution conductor installation. The reel drive incorporates the latest in hydrostatic transmissions that allow the operator to infinitely vary the linespeed and linepull for safe, positive control during the pulling operation. The maximum desired linepull can be preset prior to pulling so that the reel drive will stall if a restriction to the line occurs avoiding damage to the conductor, towers and hardware. In the tensioning mode, the hydraulic system permits the line to be pulled at a steady and controlled tension with automatic pull back to keep the conductor suspended if the pulling force is reduced.
The central operator’s console allows the operator to completely control the pulling operation with optimum visibilty of the pulling rope. Operator controls include linepull, linespeed, holding brake, levelwind and engine controls.
