Trenchless technology, such as Horizontal Directional Drilling (HDD), is a method of installing underground utilities without the need for open-cut trenching. This is particularly valuable in congested areas where cutting through roads, sidewalks, and existing infrastructure is not feasible. The process involves drilling a pilot hole along a predetermined path and then reaming it to a larger diameter before pulling the cable-carrying conduits into place.

Ningbo Changshi provides essential equipment that directly supports these trenchless projects, including:

• Cable Pulling Winches: Powerful winches with precise tension control are critical for pulling heavy and long lengths of conduit and cable through the drilled holes.

• Swivels and pulling grips: These are used to securely attach the cable to the pulling winch and to ensure the cable does not twist during the pullback operation.

• Hydraulic OHTLstringingequipment.com/Reel-Stands--Cable-Winders.html target='_blank'>Reel Stands: These stands are used to safely manage the large, heavy cable drums, ensuring a smooth, controlled feed of the cable into the conduit.
