Grab Type Ship Unloader Cost Effective Continuous 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.
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.
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
All the ship unloaders are designed based on our client`s technical specifications and applications, so the technical discussion meeting is essential before the project proposal stage.

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.
3. Hopper system
The hopper unloading system of the ship unloader is composed of coal hopper, feeder, fork hopper, coal spreading baffle, windshield, two way chute and buffer bracket.
4. Grab bucket hoisting mechanism(mechanical differential four drums)
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.
5.Grab bucket(wire rope reeving system)
6. Luffing mechanism
The luffing mechanism of bridge-type grab ship unloader is composed of motor, brake, reducer, drum and safety brake.
7.Wire rope reeving system of luffing mechanism
8. Cantilever safety hook device
When the cantilever of the ship unloader is luffing to 80 °, the safety hook device is used to hang the cantilever and loosen the steel wire rope at the same time. The safety hook is usually driven by hydraulic cylinder or electro-hydraulic actuator.
