STEEL TELESCOPIC COVER
Steel telescopic covers are formed from cold-rolled steel or stainless steel and configured around the guideway profile, travel and mounting direction. Standard designs operate up to 30 m/min; custom high-speed designs from 60 to 120 m/min require synchronized mechanisms, guided rollers and suitable buffering. A standard pull-type cover must not be used at high-speed ratings.
