A clamshell bucket, typically controlled by winches and wire rope, digs and hoists bulk materials from the transport vessel, lifting and discharging it into an onboard hopper . As this process is repeated, various types of feeders at the hopper discharge load the material onto a conveyor for transporting to its destination or transfer point.

Common use cases:

  • Electric power

  • Ports and terminals
