The large bridge type grab bucket unloader is a large-scale equipment used to transport solid bulk cargo from the cabin to the coal conveyor belt on the dock. The main material retrieval device is the grab bucket. After the grab bucket grabs the loose material from the ship, it is unloaded into the conical hopper and sent to the belt conveyor on the dock through the hopper discharge port, and then sent to the yard.
The large bridge type grab bucket unloader has the characteristics of fast speed and high efficiency, and is suitable for unloading ships at large, medium, and small port terminals or power plant terminals.
The lifting, opening, closing, and translational movements of the grab bucket of the ship unloader are mainly coordinated by the support, opening, closing, and trolley mechanisms. The three mechanisms are respectively driven by the support motor, opening and closing motor, and trolley motor through the drum to drive the steel wire rope to jointly drive the grabbing motion.
When the large bridge type grab ship unloader is working normally, it often needs to translate the entire machine, which is completed by the trolley walking mechanism. In order to prevent the boom from colliding with the upper structure of the ship or encountering typhoons, the front beam can perform pitch motion, which is completed by the pitch mechanism. The large bridge type grab ship unloader can be operated by a driver in the cab, and the cab can complete all necessary operations and displays.
