Hand-crank winch fly facilities

The Manual winch fly facilities are usually used for lifting loads higher than those of Manual fly facilities and for which the lifting speed is not important, for example for the trusses of the stage lights.
They are used both with Fixed pulleys systems and with Flyloft systems, above all for their economy compared to the Motorized fly facilities with fixed pulleys and the Motorized fly facilities for flyloft.
Due to the importance of the load they use steel cables and metal trusses, usually Aluminium trusses.
