Grab Type Ship Unloader Belt Type Continuous Ship Unloading System
Continuous 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.
