This Ship Unloader is with 4 drums differential compensation tow trolley, can do travelling by rail on port in
form of working or unworking. Whose effective working travelling distance is +_170 metres, ship unloader
can be used for unloading coal(its density is 0.85~1.0t/m3), whose capacity is 1500t/h, max capacity is 1800t/h.
Coal shipped by 35~50 thousand tons transportation vessel to port, then be unloaded to Hopper by Grab,
max outreach length of ship unloader is 30m, (the distance from railway center of sea side to the end of sea side).
After then, Coal will be exerted from hopper by feeding belt, and then be delivered to any one of the two ground
strap machines through the switchable fork hopper, finally delivered to transferring storey.
Ship Unloader has self-installed buffering carrier idlers, which can reduce the impact force from the bulk
materials to the ground strap machine.
We use the dustproof baffle enclosing the hopper and spraying system to prevent the dust floating, on the upper
side of hopper has been installed water supplying pipes and injectors, water in pipe can be outputed through
self-installed water tank, while water will be carrying from all water supplying spots to the water tank by water
Ship Unloader has installed safety ancher devices and wind proof adjustable rigid handle, to prevent wind in
unworking form. Boom of Ship Unloader can make luffing up to 80 degrees, without disturbing pulling in and
pulling out for ship.
Ship Unloader supply the power and communication through the power wire from the wire drum, with power
sources 6kv, 3-phase, 50Hz.
The control devices of ship unloader can be realised by digital control timing driver, while progarmmable
controller adopts imported devices.
Ship Unloader has equipped with advanced digital controlling system, automatical assistant controlling system,
and advanced communication system, which allows ship unloader work safely and reliablely, with highly
automation, having net control linked to centre of port.
Ship Unloader consists of the following mechanical parts:
1) Gantry traveling system
4) Jib luffing system
5) Movable operator's cabinet, luffing controlling cabinet, and second electric control cabinet.
7) Feeding belt
8) Baffle against coal dropping and returning system
9) Hoisting, opening and towing system
10) Spraying water against dust floating
11) Lift, laddles, patform, and aisle
12) Power unit, wire reeling control devices
13) Ancher, windproof wire rope
14) Mechanical, electric cabin
15) Trolley and towing system
16) Crane for maintenance
