NemaX^® Grab

NemaX^® is our flagship four-rope mechanical grab, built to increase your productivity by at least 10%. With a wider opening, low dead-weight and wear-resistant 450 HB steel, it turns every cycle into more payload and fewer clean-up passes. Helping you cut demurrage costs.

Below is an example based on iron ore handling. Use the calculator to estimate potential performance gains for your own operation.

15% Lighter = more bulk per cycle 20%

20% Faster closing and opening = more cycles per hour

30% Larger footprint = faster cleaning up

01 Features & Specifications

Additional features & specifications

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

This graph shows how unloading productivity increases with the NemaX opposed to a clamshell grab.

Because NemaX^® carries less dead-weight, more of your crane’s capacity goes into payload. Combine that with a shorter open/close cycle and you get more productive cycles per hour. The bigger footprint and high stability guarantee a consistent filling of the grab, resulting in extended free digging phase combined with a shorter cleaning-up phase. The result is a shorter turnaround time and lower demurrage, vessel after vessel.

Marc Smeets

SMT Shipping

"Our handling speed increased from 1,000 to 1,250 tons per hour. The NemaX paid for itself more than four times in its first year. "

Paulo Ribeiro

VLI Pecém

"We now unload a ship in four days instead of five. Savings in demurrage costs are considerable, to say the least."

Service & maintenance

From commissioning to years of operation, we support our customers throughout the full lifecycle of the grab. Our service teams provide technical assistance, inspections, and guidance whenever needed, helping operators keep performance predictable over time.

Spare parts availability

All spare parts remain available throughout the entire lifetime of the grab. This ensures repairs, replacements, and upgrades can be carried out without uncertainty, even many years after delivery.

Documentation & guidance

Each grab is delivered with comprehensive manuals, inspection guidelines, and welding instructions. Combined with the manufacturing data book, this documentation provides full transparency and supports safe operation, maintenance, and repairs.

Grab selection can be hard

Selecting the right grab and ensuring you got all the information for your team can be a challenge. Most common questions are listed below, still need help then contact us.

Our grabs are designed to help reduce risk through engineering details (e.g., accessible harness points, smooth/flush contours), and are validated with documented processes (e.g., 60-point inspections, International Organization for Standardization (ISO) 9001 certificates, Finite Element Analysis (FEA) summaries, proof-load testing).

Safe operation always depends on trained personnel, correct procedures, and the crane/terminal’s own safety policies.

Planned inspections at regular cycle intervals (e.g., basic checks around 10 000 cycles; deeper inspections around 100 000 cycles) are recommended by Nemag.

Wear parts and kits are available and can be delivered with your purchase.

Typical dispatch target for stocked parts is under 48 hours to keep downtime low.
