Ship Unloader System Grab Type Ship Unloader System Bulk Materials Ship Unloading System
Mechanical (electric) differential bridge-type ship unloader is a suite of effective, reliable and high performance unloading appliances customized to the port and terminal business handling dry bulk cargoes.
The connection of the main steel structure of the ship unloader adopts rigid connection, and the rigidity of the whole machine is strong enough.
Rolling T-section steel is adopted for the front and rear girder of the ship unloader and the trolley rail beam without fillet weld, to avoid weld fatigue cracking that may occur when the trolley wheels are rolled back and forth.
