The central double wedge principle

The development of this precision wedge was based on the new double wedge principle. This involves the use of two wedges to provide levelling, rather than one. Both wedges move towards or away from the loading centre symmetrically and with zero clearance. The central loading point remains completely rigid and stable.

The distribution of the load over two wedges halves the forces exerted on the lifting mechanism, enabling the effortless and precise levelling of extremely heavy machines.

The torque for the setting screw is just 4 to 6 Nm per ton. The maximum levelling load per support point is an impressive 15 tons for DK-2, 25 tons for DK-3, and 40 tons for DK-4.

Application

  • heavy machine tools for processing crankshafts and camshafts or rollers
  • high-speed milling machines
  • boring and milling machines
  • horizontal and vertical machining centres
  • transfer machines
  • surface grinding and laser cutting machines
  • die-casting and plastic injection moulding machines.

No horizontal machine movement

Central fixation of bearing parts thanks to stable centring sleeve through which the floor bolt passes. The levelling screw and centring sleeve are on a single axis and prevent asymmetrical forces from acting on the lifting mechanism.

The central loading point

remains completely rigid and stable The patented double wedge system enables central attachment and bolting. The adjusting screw and levelling screw are in the centre. Both wedges move towards or away from the central loading point symmetrically and with zero clearance.

Full-surface and stable machine positioning

Spherical machine supports using large, spherical discs (calottes) to compensate for uneven floors.

Levelling safety

Easy determination of the lowest and highest wedge position, since these positions are blocked with stops.

Machines remain precise and stable for their entire service life

The solid DK-2 double wedge provides a vertical rigidity of 5000 N/μm and ensures precise production over many years.

Aesthetically pleasing, modern design

Cover to prevent dirt penetration.

Reduced installation time thanks to effortless and precise levelling

Low torque for high levelling, which takes place with zero clearance and with a force starting at just 4 to 6 Nm per ton; thanks to the distribution of the load over two wedges, the forces are halved; zero clearance when changing the levelling direction.
