The clamping arms can be mounted on the square shaft of the power clamp in two angular positions offset by 90° and in a mirror-image configuration. Depending on the application, this can offer better accessibility in the clamped or open state. When mounting the clamping arms, the marks on the arm and on the clamp pieces must be situated on the same side. The screws that are located closer to the mark must be tightened first. For power clamps of type S, the clamping arms are loosely enclosed. |
