Nemag has developed a new grab for iron ore handling that is claimed to offer 10% higher productivity than all comparable clamshell grabs. The company said that new “nemaX” grab is also far stronger and requires the lowest maintenance costs ever.
“Dry bulk terminal operators are always looking for ways to increase terminal efficiency,” stated Nemag. “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 has introduced the most productive grab for iron ore, the nemaX.”
With overcapacity in the dry bulk market, terminal operators need to achieve high productivity and fast vessel turnaround times, in order to remain an attractive proposition for investors. According to Nemag, the cheapest way to increase productivity of an existing grab unloader is to exchange the grab for a more efficient one.
“The lowest deadweight combined with speed of closing and opening are of paramount importance, and that’s exactly what Nemag’s new grab offers,” the firm said. “Through exhaustive computer simulations, Nemag has succeeded in
developing a new generation of patented grabs for handling iron.
“The nemaX features a deadweight efficiency of only 25-28%, and a grab ratio of 2.5 to three. 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.”
