The Viper machine, suitable for buildings up to 60 m, is a variation of the Venus machine fitted with a mast to allow travel over obstacles on the roof. The overall size of the trolley is considerably reduced because of the counterweights fitted to the end of the jib. As with the Venus machine, the Viper is fitted with a SOLO or ALTA cradle onwhich are mounted the TIRAK hoists and wire rope winders. Advantages:
* reduced dimensions of the trolley
* easy travel over the parapets
