It is also called Pneumatic pilot ladder because of its power type. Some vessels install pilot ladder winch to avoid potential accident from manual operation, or to make operation easier due to ladder length and weight. Crews don’t need to shoulder the ladder from deck store room. The only difference is that this ladder should be covered with cloth to avoid corrosion by sea water or rain, because it is installed on main deck near to accommodation ladder. Without this pneumatic winch, the ladder structure is completely same as others. We can trade ladder winch together with ladders made in China or any origin you prefer.
