The new frame in welded stainless steel increases the torsion rigidity level (already the absolute top in its category) of the Z 9100 by 5%. The total weight has been decreased by 4 kg. The mass distribution has been maximally optimised and the design has been modified in order to have a better grip distribution. The result is a extraordinary sensation of compactness and solidness, incredible handling and an absolute precision in every path, with the possibility to block integrally all four swivelling wheels in order to make the transfer of the corpse an easier operation. Besides having an improved functionality of the frame, Z 9100 is characterized by a stainless steel basin, with the possibility to insert a draining element. A robust undercarriage with a special top finish, guarantees easy cleaning and an efficient sanitization. The constructive philosophy guarantees a long lasting performance without costly substitution of components or technical interventions.
