Marine Hatch Cover System General description
We have abundant experience in designing hatch cover system，are good at designing, manufacturing, installing all
kinds of hatch cover system.
To meet customer's requirements, our hatch cover system is divided into translation type, folding type, rolling and
tipping type, lifting away type.Control mode is engine local control of manual direction valve and there is a control group valve besides every cabin. The power supply is to use two sets motor pump units as spare parts for each other. It can be collocated a portable pump station for emergency operation according to customer's requirements.
Our products are simple structure, covenient operation, cheap cost, safety and reliable performance, they are widely
used for large bulk vessel, containers and etc.
Self-contained open-circuit compressed air breathing apparatus are used widely for fire-fighting, chemical industry, shipping, laboratory, mine, pertroleum, warehose, factory and metallurgy. It can provide effetely respiratory protecting from toxic gases for fire-fighting, life-saver, rescuer and operator who working in thick smoke, steam, and oxygen deficiency hazardous atmosphere.
The product was awarded the certificate of inspection by state quality testing center for fire-fighting equipment, and it is up to the China standard of GA124” self-contained open-circuit compressed air breathing apparatus for fire-fighting.

Marine Hydraulic Steering Gear Description
1000kn·m test stand for hydraulic steering gear from our company is the biggest one in China
recently. It can simulate practical work condition of ship to load the product during navigation, in addition,
it use high-precision digital instrument to automatically test and record the output torque and mechanical
efficiency of tested steering gear at any rudder turning angles.The test stand is used for test our steering
gears, such as linked cylinder type, ram type and rotary vane type steering gear.

The electro-hydraulic steering gear is mainly composed by a set of rudder device, electro-controlled pump station, emergency system, operation console and spare oil tank.
The rudder devices consist of rudder-pushing device, manual isolation valves, rudder angle indicator etc. It can be sorted of one single rudder unit, double rudder units, special orders can be 3~4 rudder units.
The rudder-driving device is a mechanism which can change hydraulic energy into mechanical energy, by driving the rudder stock moving.
The electro-controlled pump station is a device which supply and control the hydraulic energy. The fuel tank, motor pump group and hydraulic system control valves are integrated.Normaly, the steering gear equipped with two sets of pump stations and can be used alternately. Due to the system's transform can be quick and convenient, the rudder can be controlled both in the cab or engine room.
There are many emergency system types according to different navigation zone, such as handle pump, bladder accumulator and DC motor pump sets.
The operate methods of steering gear include manual operation, servo-control, automatic control.
Different ships choose different control way.
We can supply all kinds of roller fairlead according to different standards. We can also make these products according to buyer's drawings.
Marine fairlead is used for guiding ropes in ship mooring and will not breakdown.They can be welded either into the bulwark or on deck. Various sizes can be provided,it features durable, long lifetime.
Used extensively throughout the marine industry and in certain rigging applications, fairleads are found on the majority of commercial shipping vessels.
1.can be made by cast iron,cast steel or as requested.
2.short manufacturing term and prompt delivery.
3.Surface Treatment:Polished, galvanized or bitumen painted
