Load limitation on lifts

The load an elevator can carry is defined during its design. Therefore, it is necessary to provide a load limitation system preventing its use in case of overload.

SENSY has developed a full range of load cells, load pins and management electronics to measure loads and to prevent any use in case of overload.

This concerns in particular the industrial lifts for civil engineering construction for which SENSY has developed thru hole force sensors intended to be mounted between the load-bearing structure and the cage. An adapted version of the BRIDGE BOY provides overload protection for this specific application.

To meet the standards applicable to lifting systems intended for transporting people, these sensors can withstand a breaking load equal to at least 10 times their nominal capacity (coefficient 10).
