Crane concept
Transshipment and floating crane setups are built to move cargo continuously. Cranes work from a barge or ship and cycle between pick-up and discharge with minimal travel. The goal is a stable rhythm: fast closing, controlled rope loads, clean discharge into the hopper, and uninterrupted flow to the conveyor or receiving hold. With the right grab, you keep cycle times short and productivity high, even when conditions change.
Operational challenges
Revenue depends on transfer speed and uptime. Any slowdown increases fuel use, vessel waiting time, and cost per tonne. Rough conditions make trimming difficult, and maintenance stops cut capacity. Choosing a grab with low self-weight, high payload, and simple maintenance helps protect performance. The objective is clear: more useful tonnes per hour, fewer interruptions, and predictable cycles throughout the shift.
Choosing the right grab
NemaX is the reference choice for transshipment. Its low self-weight and optimized geometry support fast penetration and clean release, which shortens the cycle and lifts payload efficiency. Fewer components reduce maintenance, increase availability, and extend service life. During trimming, NemaX maintains control and productivity, even when conditions prevent the use of support equipment. Where operations also handle conventional duties, a heavy-duty clamshell remains a reliable alternative.
