Pit ladder type D
ALU stepladder with a hook-on profile that can be flexibly adjusted on a pair of rails for an individual shaft pit depth and is used to lock in the door threshold. The stepladder has replaceable, non-slip ladder shoes. The square ladder rungs are pressed together with the ladder rails and are ribbed to prevent slipping. Outer ladder width approx. 350 mm, rung spacing 280 mm. The ladder is available in various standard lengths. Each standard length covers a certain interval in which the shaft pit depth can vary. However, the required shaft pit depth must be observed in accordance with DIN EN 81-20 / 50!
The ladder is fastened to the shaft wall using a knotted chain (approx. 2.5 m long) with the appropriate fastening material (plug-in anchor dowel with three nuts and washer). These additional parts are completely supplied.
The pit ladder type D complies with DIN EN 131 + DIN EN 81-20/50 requirements (in combination with our floor stop plate).
