The multipurpose clamshell grab

Home
The Grapner is the only clamshell grab for knuckle-boom lorry cranes worldwide able to dig even in hard soil without damage to the crane and to grab rocks up to 4 tons safely.
Keywords: Grapner, clamshell grabs, lorry crane, grapples, excavator, earthmoving, rocks, bucket grab, knuckle-boom crane
Its patented kinematics and its high quality manufacture by a swiss company guarantee a lasting performance over many years.
The Grapner allows, through the use of knuckle-boom lorry cranes instead of excavators, to speed up the execution of typical small to medium excavating jobs.
