For a Cairo new underground line, we have designed a support beam gripper with following characteristics:

Length 2 m, weight 700 Kg

This gripper, controlled from the excavator cabin on which it was mounted, allows to turn upside the support beams after lifting it up. The gripper consents a precise positioning along any axis.
