Cranes maintenance


Technical assistance while using cranes aims to control ropes and / or chains of hoists and winches, as required by law. The operational staff of Sigma Group, provides, at the customer’s site, periodic checks and assistance.


During the days of assistance, all mechanical and electrical parts of the crane are subjected to careful checks (motors, wheels transmission, cables, switches, etc...) and everything else that is used to secure the load on the hook of the crane itself.


A careful and responsible control that only the professionalism acquired over many years, can guarantee
