Bridge-Type Grab Ship Unloader Electrical Control System is suitable for ship unloading operations at ports or coal unloading operations for ships at power plant terminals, featuring fast speed and high efficiency. The bridge-type grab ship unloader can operate on tracks, with sufficient clearance height under the gantry for transport vehicles to pass through. The grab picks up bulk coal from the ship and unloads it into a conical hopper. The coal is then delivered through the hopper outlet to the belt conveyor on the dock, and finally transported to the storage yard. The front boom can perform luffing movements.
