Mechanical(electric)differential bridge-type ship unloader
The ship unloader is installed on the port,unloading dry bulk cargoes(coal, ore, mineral powder, cement, coke, ash, grain etc) from vessel`s hold via grab bucket. Discharging dry bulk cargoes to the hopper, then to the conveyor belt via hopper. By conveyor belt the dry bulk cargoes are conveying to the stockyard for storaging.
