Most efficient solution for your dry bulk handling

Through exhaustive computer simulations, Nemag has succeeded in developing a new generation of patented grabs: the NemaX®.

This innovative & strong grab delivers more than 10% higher productivity than all comparable clamshell grabs, with the lowest maintenance costs ever.

A good design, in combination with the use of high-tensile wear resistant steel as well as an excellent bearing system, makes this a strong grab with a relative low dead weight and high productive capacities.

"Today, we unload a ship in four days instead of five. The savings in demurrage costs are considerable, to say the least."

- Paulo Ribeiro, Spec. Port. Operations Technician at VLI Pecém.

Case study: VLI PECEM

 

"The NemaX grab has helped us achieve so many great results. Our hourly unloading rate has increased with 48%, there's a notable improved ease of maintenance and the standard crane load capacity has increased with 5-6 MT"

- Jonas Chupe, Head of Procurement at Voestalpine Texas Group.
