The DP-20-4H is a versatile, hydraulically powered four drum puller designed for medium distribution stringing. It can also be used as a pilot line winder for heavier distribution. Power is transmitted from the engine to the reels through a common hydraulic drive train. A diamond leadscrew levelwind, accommodating one reel at a time, aids in an even wrap during pulling.
Each reel is equipped with a mechanical clutch to allow selective reel rotation and a mechanical brake to retard overspin. 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.
The central operator’s console allows the operator to completely control the pulling operation with optimum visibility of the pulling rope. Operator controls include linepull, linespeed, holding brake and engine controls.
