Handling coils by forklift truck





This gripper may be used for material handling by cranes, trucks, industrial robots or manual handling or as a part of an artificial hand. Size can be designed for any purpose.






Equipment for handling barrels up to 200 kg and up to Ø600 mm.

Friction is increased by increased surface area. (Compare with tires in Formel-1)




This gripper, which is suitable for any type of handling equipment, meets the requirements as a tool for flexible gripping. It can grip many different work pieces without having to be changed.

Market response has shown traditional grippers gives quality problems because of too few contact points.

This gripper is more cost-effective than tool exchanger systems. The total price is lower, no time loss for exchanging the tool and less service.

If it grips a rigid detail it normally has more than four points of contact. For any cylinder there is usually 10 points of contact when two fingers are used. There is possibilities to fix formed rubber at the contact surfaces. The gripper can have one finger working together with a "thumb" or more than two fingers depending upon the needs.

Each finger has a very simple design giving high reliability.

The gripper can also be designed for improved artificial hand.

The grippers can be combined for different purposes

Mounting flange will be delivered to fit equipment specification.

Any sizes of the gripper can be quoted.

The innovation has been honored at the opening ceremony of the Stockholm International Fair 1999:


Besides, in 2001 the gripper has got a price at Väsman Invest Competition of best Swedish Innovation.
