The JKB SGKTR hydraulic brick and block clamp is basically the same as the SGK clamp, but it is additionally equipped with a switchable function adjustment, whereby the clamp width can be operated from the elevated seat/high-standing position of the truck-mounted crane. This is switched in a special way by means of the rotation function of the hydraulic rotator on your crane. Your operator no longer has to manually set the clamp width directly at the clamp. The screw spindle for width adjustment is controlled by a hydraulic motor with mechanical transmission to the spindle and enables stepless width adjustment. You are therefore no longer dependent on the standard adjustment positions of the SGK clamp. The SGKTR brick & block grab is standard equipped with parallel guidance.
