Grab Type Ship Unloader for Coal and Ore Handling Ship Unloader Bulk Material Handling Ship Unloader
The ship unloader is mainly installed on the port,unloading dry
bulk cargoes 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.
The traveling of the mechanical differential grab ship unloader trolley depends on a driving motor to connect the two differential reducers through the a coupling. Through the differential transformation of the gearbox, the grab lifting is transformed into the transverse movement of the trolley.
