The V200 is a vertical JOMY ladder provided with a safety cage. This ladder can move horizontally over an I-shaped or O-shaped rail.
An horizontal access balcony or steps to cross roof edges can be added to increase the safety at heights. Folding landings can guarantee safety and give the workers moving space to move around at heights.
The disadvantages of a mobile ladder with safety cage is the aesthetic appearance. It can also be inconvenient when cleaning the windows.
