Polypropylene hanging Ladder
Polypropylene hanging Ladder
Lane International developed the first steel reinforced polypropylene hanging ladder. The ladder is constructed of the same tough copolymer polypropylene as the Lane Poly Manhole Steps, and has the same tread design for safe, rust-free longevity. The ladder is designed to hang from the bottom step in a manhole shaft into the base section. The contractor now has the freedom to arrange the steps in the proper and safest location. The ladder rids the precaster of the guess work of trying to determine the proper location of the steps prior to the man hole being delivered to the job site. This eliminates the contractor having to remove the steps, plug the old step holes, and reinstall new steps into the proper position.
