STANDARD RAM - SMALL SIZE The single-stage standard ram series is completely matched to each other with sizes and extension lengths. The smaller ram creates an opening into which the next larger ram is then inserted. The R 410 has a minimum overall height with a comparatively large stroke with 750 mm extended length. The claws can be rotated through 360°. Sensitive operation of the star grip is possible without twisting the wrist. The easy-grip claws on the piston rod and in the cylinder base provide a secure grip on sloping and smooth surfaces.
