Mechanical dredging clamshell
Round nose Grab (clamshell) The mechanical round nose grab is specially designed for heavy-duty dredging. The shells and knives are manufactured in a round shape for more strength and more penetration power into the very hard soils mixed with rocks. The grab is manufactured of high wear resistant steels such as Hardox 400, Weldox 700 .
The rotation points are equipped with heavy duty bearings. The bearings are double sealed to prevent entering dirt into the bearings. The shells are fitted with heavy-duty interchangeable teeth, which are easy and quick to replace. The grabs can be manufactured in any weight and capacity you require. In a two- or four rope execution.
Flat nose digging grab (Clamshell) These grabs are suitable for digging and dredging Clay and/or Sand. The grab is manufactured of high wear resistant steels such as Hardox 400, Weldox 700
The rotation points are equipped with heavy duty bearings and heavy duty shafts. The bearings are double sealed to prevent entering dirt into the bearings. The grabs can be manufactured in any weight and capacity you require. In a two- or four rope execution.
Level cut clamshell The mechanical Level Cut Clamshell is specially designed for environmental mud dredging. Because of its excellent design characteristics the clamshell closes nearly horizontal and is therefore able for precise removal of contaminated sediment. The shells are fully closed and because of its design the turbulence is minimised.
The grab is manufactured of high wear resistant steels like Hardox 400, 500 and T1. The grabs can be manufactured in any capacity you require. In a two- or four rope execution.
