Our JKB SGKPV hydraulic brick and block clamp features stepless adjustable gripper width set by the position of the lower adjustment cylinders. This brick and block clamp is fitted with switchable function adjustment that allows the clamp width to be controlled from the elevated operating position of the truck-mounted crane. This is ingeniously switched using the rotation function of the hydraulic rotator on your crane. Your operator therefore no longer needs to set the clamp width directly by hand.

What’s more, the SGKPV brick & block clamp is easy to operate and features extra cylinder rod protection for the lower adjustment cylinders, which minimises risk of damage.

This clamp is not available with parallel guides.
