Jacob's ladder (rope ladder)
A rope ladder is referred to as a Jacob's ladder (named after the biblical Jacob's ladder ) in seafaring .
Jacob's ladders are simply constructed rope ladders or rope ladders in which round rungs are inserted between the usually four cardelike natural ropes and secured with cross straps. They are much easier to use than pilot ladders or gangways and are used for outboard work in the harbor or for the lifeboats. When not in use, it is not left hanging overboard, but rolled up and put away.
Types
Three different types of rope ladder are used in shipping:
- Pilot ladder ( English pilot ladder ), with flat steps and at a distance of two meters an Spreizstufe which prevents the twisting of the tailgate
- Embarkation ladder ( English Embarkation ladder ) as the pilot ladder , but without Spreizstufen
- Jakobsladder (Knüppelleiter) ( English Jacob's ladder ), with round steps
The safety of the individual ladders decreases from pilot to embarkation to Jacob's ladder.
