Cylindrically Shaped Rope Ladder 
A cylindrically shaped rope ladder is safer than 
conventional types, particularly for children, elderly 
people, or the partially crippled, and is useful where a 
sling and winch operation is not feasible. People who fear 
heights feel safer with this ladder because the climber 
ascends and descends inside the structure. The cylindri-
cally shaped ladder (see figure) is a rope net held in a 
cylindrical configuration by supporting metal hoops 
which are spaced at vertical intervals along the ladder. 
Being of rope construction, the ladder is easily handled 
and transported. In addition to the many general applica-
tions, the ladder has been used for internal inspections of 
empty liquid storage tanks.
