With over 45,000 installations worldwide, 3S Lift Climb Assist has been proven to be safe, reliable and easy to use

By using variable-frequency vector control technology, the system provides lifting force for both ascent and descent. The lift speed adapts to operator’s speed automatically. Starting and stopping do not need hand operation, meaning user’s hands are always safely on the ladder.

CA-2D Overview

3S Lift Climb assist can retrofit to any existing turbine ladder. This provides a low cost solution for climbing assistance. It is easy to install and maintain.
