Product Description
Bulk Cargo Belt Type Ship Unloading System Ship Unloader Bulk Material Handling Ship Unloader
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 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.
Bridge-type ship unloader including self-propelled trolley type and wire rope drawing trolley type. Wire rope drawing trolley type including main and auxiliary trolley type and differential four drums trolley type. Differential four drums trolley type including mechanical differential four drums trolley type and electric differential four drums trolley type.
Mechanical (electric) differential bridge-type ship unloader is most advanced and widely used today. Its hoisting system, opening system and drawing system, are controlled by four drums. It was particularly designed for specializing in professional bulk handling solutions that provide very highest levels of performance.

Main structure of bridge-type grab ship unloader
Mechanism of bridge-type grab ship unloader
1.Traveling mechanism
The driving method of traveling mechanism is multi drive. Traveling mechanism is composed of driving device, traveling support device and safety protection device. The traveling support device adopts the wheel group with balance beam, the wheel adopts the rolling bearing wheel with double wheel edges, and the number of driving wheels shall not be less than 50% of the total number of wheels.
Most of the driving unit are three in one reducers, which can also be combined by reducers, brakes and motors through couplings
2. Main structure of bridge-type ship unloader
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.
