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 and penetration—so the grab bites deeper on every first pass. Combine that with a shorter open/close cycle and you get more productive bites per hour. The wide footprint and high stability (low center of gravity, fewer rocking moments) keep those bites consistent longer, delaying bulldozer assistance and leaving a flatter floor. Net result: a shorter clean-up phase, faster hatch turnarounds, and lower demurrage—cycle after cycle.
