CRX100 Excavator Datasheet

The CRX100 is a seafloor excavator tool skid for integration with a work class ROV. The excavator is designed for seafloor conditioning, collection of large samples from seafloor mineral deposits and to test rock cutting head designs at depth. The CRX100 can be configured with a bucket to clear the cutting area before the dual counter-rotating rock cutting head is used to excavate material to the hydro cyclone for separation and storage.
