For underwater operations Verstegen offers grabs for maintenance dredging (mainly silt and mud) and special grabs for digging operations (clay and hard ground layers).
The grabs are available in two and four rope version.
The inner side of the scales is smooth, without any abrupt transitions. This minimises the resistance during the digging in to the bottom and also makes it easier to unload sticky materials, like clay and mud.
Different types of cutting edges (scale lips)
The grab’s bottom lips can be delivered with contact lips without teeth. For hard layers and different to penetrate materials, we recommend lips with teeth. There are bottom lips with removable or exchangeable teeth and lips with permanent teeth (cut from the bottom lips).
Permanent teeth (cut into the bottom lips) are very suitable for extreme hard layers.
