Innovation: the Hélicrab staircase

The Hélicrab is a new staircase design patented by Entrepose Échafaudages which provides an ideal solution for access on building sites. Its small footprint (1.5 m x 1.5 m) means that it can be set up in confined spaces and it is easy and safe to use.

It is fully compatible with the Multicrab scaffolding system and can be erected to provide a wide range of access heights and angles. It can be used to access several heights at the same time (in multiples of 50 cm).

Particular attention has been paid to safety: Hélicrab includes erection guardrails and a special access platform so that it can be erected and dismantled in complete safety. The lightweight components mean that the staircase can be erected without lifting equipment.

Hôtel de Crillon, Paris

The Aulnay branch has been working on site at the Hôtel de Crillon since December 2013.
The initial contract was for scaffolding work on the whole of the façade overlooking rue Boissy d’Anglas (1872 m2, facing the US embassy), around the two courtyards (3364 m2) and for the construction of a 2900 m2 temporary roof for the entire building.
Since then, the Aulnay branch has installed several complementary structures such as: working platform, various stairways and access cranes, as well as the scaffolding to support the tarpaulin hiding the Algéco site facilities modules, which has just been replaced by a decorative curtain depicting how the front of the hotel will look once the work is finished.
