In addition, a permanent-electro system allows additional savings due to lower maintenance:
– does not require back-up batteries (with electromagnets the batteries must be checked and replaced periodically)
– it does not overheat, therefore it does not wear out (the windings of the electromagnets suffer from performance decay)
All TECNOLIFT handling systems are permanent-electro.
