As is well known, the new UNI EN 81-20: 2014 standard, together with UNI EN 81-50: 2014, imposes a 5 mm deformation limit on the elevator lift resulting from the sum of the following two contributions:
1) deformation of the guides themselves;
2) deformation of the structure (guide brackets + crossbeams + uprights).
In order to provide our customers with a formal and complete document that can be used during the final test, regardless of the type of procedure used, we have resolved to take the responsibility to certify the conformity of the entire installation (structure and lift) to new legislation by means of a total calculation, which includes all the above structural elements.
In order to be able to perform this project properly, including structural elements of the elevator, our designers will need substantially:
a) a dimensioned drawing of the used guides section;
b) detailed construction design of the geometries, machining and materials used for the guide brackets (if not included in our supply);
c) to interact with the lift manufacturer in order to identify structurally optimum solutions in the interest of the customer (eg change the profile of the guide or, if it is cheaper, reduce the pitch of the brackets).
In the impossibility of receiving and managing the above, Indastria will only calculate the metal structure without considering the loads given by the lift, in this case, will limit the structural deformation contribution to 3.5 mm.
