Hydraulic Digging / Dredging Clamshell Grabs

These grabs are specially designed for heavy duty digging and dredging purposes. Given our country's long historical struggle against the water, the Dutch have become specialists in the field of digging and dredging.

The grabs can be executed with open or closed shells with dust covers, depending on the job and the type of material to be handled.

The grabs are manufactured of high wear resistant steels. All bearings are heavy-duty and sealed for high performance.

Grab execution

The grabs can be executed with:

  • Mechanical rotator for 270˚ rotation (The mechanical rotator will standard be executed with 200mm height compensation)
  • Hydraulic rotator for 360˚ hydraulic rotation
  • Hydraulic 360˚ rotation by means of slewing ring and hydro Motor
  • Without rotation (fitted with plate and lifting eye(s)

The shells can be executed with a clay ejector to push out clay and other sticky materials. 

The open shells can be executed with a flat knive, with integrated teeth (standard) or with interchangeable teeth. Optional the grab can be executed with dewatering sleeves in the shells.

The grabs can be manufactured in any execution weight and capacity you require.

A suspension link for connection of the grab to the crane can be manufactured according to your requirements.
