DALIS BASIC economic cover system

DALIS Basic :

The Dalis Basic system has a large manoeuvrability. It is a PVC tarpaulin carried by sliding arches in rails. The storage principle is patented allowing an implementation and an extremely fast storage.
This economical system makes it possible to secure pits in accordance with the instructions of the Carsat (R468& R469) at a moderate cost (250€/linear metre except installation)

Operation:

The Dalis Basic system consists of a tarpaulin carried by sliding arches and a storer for storing the entire cover at the end of the pit.

The very compact storer limits the footprint in the pit to 650mm.  The storage mechanism is entirely passive: By storing energy in springs during storage.  It helps to limit deployment efforts allowing manoeuvring by a single operator.
