The Grapples are constructed as follows: The claws which serve to pick up the rocks, are attached by means of a shaft to the stick of the excavator. The shaft serves also as turning point of the upper claw. The claws are made of high wear resistant steel. The upper claw is driven by the original cylinder of the excavator to the claw. The claw can be opened and closed by pulling the cylinder rod in or out.
Because of all the different stick executions of the excavators, these grabs are manufactured according to the specifications of the customer. Executions are available upon request.
