Hélicrab : commercial documentation

Fitting a safe erection guard rail Fitting the steps Erection trapdoor for safety Collective protection for erection Access between scaffolding towers Hélicrab staircases can be erected between 1.50 m square scaffolding towers to access both the working platform and the formwork. As they are compatible with the Crab system, they can be connected to the towers using ledgers. This Hélicrab staircase has been erected between 2.00 m square towers and connected using 0.15 m ledgers on one side and 0.35 m ledgers on the other. Attached to facade scaffolding Hélicrab staircases have a very small footprint and can be used where space is limited (narrow street, inner courtyard, etc.). They can be attached to facade scaffolding for access at 2 m intervals. A 6.50 m flatbed can carry the Multicrab cage components and the Hélicrab flights required for a 20 m high staircase. Access to various floor heights Hélicrab staircases can be easily adapted to the heights to be accessed. The picture shows that by using 3/4 of a turn after the first landing, you can access a floor 3.00 m higher. > Although the steps shown in this leaflet are blue, production units are hot dip galvanized. Steps can be coated in the colour of your choice. Hélicrab staircases can be erected and dismantled safely with the special erection trapdoors and guard rails. The components are lightweight for easy manual erection.
