CWSGK (with CW head plate) 4500 KG

The tough, heavy-duty SGK hydraulic brick and block clamp, which has long been widely used at brick factories and hauliers to grab full packs of bricks, tiles and kerbstones, is our most universal clamping attachment. With its fully tapered clamping arms, double lower beam and powerful cylinder, no job is too small for this all-rounder among brick and block clamps.

The CWSGK brick and block clamp can always be aligned for safe mounting and removal thanks to the CW bracket with integrated parking support. The brick and block clamp is suspended centrally below the CW bracket with integrated parking support. If your excavator is fitted with a tiltrotator, this brick and block clamp can turn on its axis. If you do not have a tiltrotator but still wish to be able to rotate the load with this clamp, you can opt for the CWSGK+R version.

The standard CWSGK brick and block clamp features:

  • CW bracket with integrated parking support
  • Set of paver plates
  • Set of extensions
  • Storage tubes for extensions
  • Pressure release valve with manometer and litre limiter
  • Parallel guide
