Abstract
A lifting arm arrangement includes a gripper head arm, a lifting arm, and a lifting cylinder. A gripper head is fastened to a first gripper head arm end. A first lifting arm end is pivotally connected to the gripper head arm. A second lifting arm end is pivotally connected to a stationary lifting cylinder part. A second gripper head arm end is pivotally connected to a movable lifting cylinder part. The stationary lifting cylinder part comprises a cylinder with a cylinder cavity having first and second cylinder openings. A piston rod with a piston is arranged in the cylinder cavity. A first piston rod portion projects from a first piston end of the piston. A second piston rod portion projects from an opposite second piston end of the piston. Working areas of the first and second piston ends are substantially equal to each other.
