Abstract:
Systems and methods for providing lifting workers up cell towers are disclosed. The system is useful on “stealth” cellular towers that do not have external ladders or climbing pegs for aesthetic reasons. The system can include a cable, a system of pulleys, and an internal or external winch. The cable can include a counterweight to enable the cable to be paid out from a storage position at the top of the tower down to the ground under its own weight. Workers can attach a harness or a basket to the cable. The winch can then pull the cable, worker, and/or basket to the top of the tower. The winch can be installed on site or can be provided by an on-site service vehicle. The system can also include a fall arrest system to prevent falls in the event of a component failure.
