KWK12 12.000 KG

JKB has developed various retaining wall clamps to accommodate straight and tapered retaining walls.

The KWK12 is the heaviest in the series.

JKB has designed various hydraulic retaining wall clamps for easy and quick movement of retaining walls.

  • Straight walls, single-sided or double-sided tapered walls.
  • Single or double foot (L or T).
  • With or without buttresses.

The contact surface with blank PU rubber prevents black prints on these walls.
Large overhead clamping cylinder with hinged clamping action or side-mounted clamping cylinder with direct clamping to the wall.
Center of gravity of these walls are often positioned off-center.
For this purpose, the JKB hydraulic retaining wall clamp is equipped with a suspension point that can be moved manually, so that the center of gravity can be moved to almost any position.
As a result, the foot of the retaining wall can be lifted horizontally, so that no high point loads need to be placed on the ends of this foot.
Risk of breakage during loading and unloading is therefore reduced to a minimum.
