PERI UP Stair 75


The lightweight aluminium flights of stairs with 75 cm widths are mounted on ledgers of the PERI UP modular scaffolding. This results in 4-legged stair towers with alternating staircase units or staircase units in the same direction with heights of up to 100 m. The PERI UP Flex Stair 75 is designed to accommodate 2.00 kN/m² loads and serves as access to working areas or construction sites. 

Flexible assembly 
Through the 25 cm grid dimension, all bays can be completely closed even in the smallest of spaces 

Easily adapted 
for accessing building openings with brackets and small flights of stairs – regardless of story heights

Fast installation 
with only a minimum number of ledgers and anchors

Una variante para espacios estrechos

Escalera PERI UP para obras y ampliaciones

Con la escalera para obras y ampliaciones pueden montarse accesos en el interior de edificios con cajas de escalera estrechas. Para ello, se colocan largueros UH más cortos en un ángulo de 90° a la misma altura y se montan zancas de escalera de menor largo y altura. La escalera para obras y ampliaciones sirve al mismo tiempo de plataforma de trabajo para trabajar en los muros. Con componentes estándar  pueden montarse accesos modulados cada 25 cm. Las configuraciones estándar están disponibles para la altura de pisos frecuente de 2,75 m.
