HE Principle oi Opration The I-Lock Spiralift ILR250 is a linear actuator that is very compact using two stainless steel bands to form a solid lifting column. The vertical band is stored in a magazine around the ILR250 and the horizontal band is stored below. The vertical band that is perforated is laid over a horizontal band that is toothed with a rotary motion. The horizontal band is raised using a series of cam rollers arranged in a helix pattern. The vertical band is then pushed over the horizontal band. The vertical band is overlapped and the horizontal band perforates the vertical...
