nemaX grab

The new grab for iron ore, >10% higher productivity than all comparable clamshell grabs, way stronger and the lowest maintenance cost ever.

15% Lighter = more bulk per cycle

20% Faster closing and opening = more cycles per hour

30% Larger footprint = faster cleaning up


Innovative solutions
Dry bulk terminal operators are always looking for ways to increase terminal efficiency. It’s also important to optimise profits for shareholders, and to increase the competitive edge. Grabs are extremely decisive for terminal efficiency. That’s why Nemag introduces the most productive grab for iron ore: the nemaX®.

The nemaX®: a new generation of grabs
The nemaX features a deadweight efficiency of only 25-28%, and a grab ratio of 2.5 to 3. This means on average that the nemaX is about 15% lighter than any comparable clamshell grab on the market. The nemaX is also the fastest grab on the market; the optimised closing mechanism enables a 20% shorter closing time, and maintains closing force on the lip plates at high levels. The result is an increase in productivity of at least 10%, starting immediately from the very first grab cycle and continuing all the way down in the hatch. In addition to this improvement, there is an additional productivity gain from extended free digging and improved cleaning up.

Compare the grab glossary

Crane capacityIs the Safe Working Load of your crane in tons in grab duty, i.e. the total sum of grab dead weight and payload.

PayloadIs the nett load of cargo in the grab. Because it’s linked with the grab weight it will be filled in automatically.

Grab weightIs the Dead weight of your existing grab. Not sure? Check your grab manual, CE declaration, or on the ID plate on your grab.

Grab rope withdrawal lengthIs the length of the closing rope which needs to be pulled out in order to close the grab (not to confuse with the total reeved in grab rope length).

Not sure about the numbers?Check the grab manual. Don’t hesitate to contact us.
