There will be a lower chance of problems and delays due to higher safety margins. It saves a lot of time as additional falling safety devices are no longer required. Tilting of longer wall panels is easier and faster. This saves time and therefore money. Moreover, operators will be less stressed. The same set of suction cups for big cladding lifters can be used to lift both roof and wall panels. This reduces investment cost and also costs for maintenance and inspection. The payback period is shorter because the machines are versatile (to be used for panels, glass and stone).
