Manholes serve as crucial access points for long-distance underground pulls. A proper setup here can make or break a project.

• Positioning and Equipment: A pulling winch should be set up at the exit manhole, securely anchored to withstand the high pulling tension. The feed manhole should be equipped with underground-Cable-Laying-Equipment-and-Tools.html target='_blank'>cable rollers and manhole sheaves to support the cable's weight and guide it smoothly around corners, maintaining the proper bending radius.

• Reducing Sidewall Pressure: Pulling a heavy cable through a bend in a manhole generates immense "sidewall pressure," a crushing force that can damage the cable. Using appropriately sized sheaves and rollers redirects this force away from the cable, ensuring its integrity.

• Communication: A crucial, yet often overlooked, part of the setup is clear communication. With workers at the winch, at the feed end, and often at intermediate manholes, a reliable communication system is essential for coordinating the pull and stopping immediately if an issue arises.
