Four lifting cylinders are hydraulically dosed for exact parallel motion. Uneven cylinder loading (for example, due to asymmetrical weight distribution or due to different friction) does not cause a noticeable stroke discrepancy. Unequal distances between tool top and base are equalised with adjusting screws. Larger separation strokes than the actual stroke length of the cylinders, are achieved by repeated lifting and supporting action. For this cylinder and piston attachments are available as accessories.
Parallel lifting device HYLA-LIFT replaces sledgehammer and crowbar, saves working time and protects tool guides.
Tilt-free, parallel lifting of tool tops even with extremely uneven weight distribution or in the event of column damage
