The BK block clamp has been specially designed to pick up interlocking, stackable concrete (“lego”) blocks on both the long and short side. It has uniquely shaped clamping arms and the lower beam is fitted with a double row of white PU gripper pads each positioned at its own special angle.

This means it is no longer necessary to change the block clamp’s width setting allowing blocks to be picked up more quickly and more safely. The pads also ensure no black streaks are left behind on the blocks.

The clamp is optimised to handle concrete interlocking, stackable concrete blocks measuring 800x800x1600 mm and weighing up to 2,500 kg.

Benefits of the JKB BK block clamp;

  • Can be used for clamping both the short and long side
  • White PU rubber means no black streaks on the blocks
  • Parallel guides for an extremely stable clamping action
  • Quick opening/closing using a single powerful cylinder
