HYDRAULIC CYLINDER
BUSINESS AREA HYDRAULIC CYLINDER

Our products provide excellent performance even in very bad conditions for product use, such as cryogenic environments in the Arctic and underwater environments such as submarines. Products are built and supplied to customers based on technology that enables optimal design based on numerous performance and experience and responds to all usage environments.
CRANE

SERVICE CRANE FOR SHIP
It is a cylinder installed on cranes used in VLCC, LNG, and LPG ships. Especially, it is mounted on cryogenic icebreakers for operation in the Arctic Ocean, so that it exhibits smooth required performance in cryogenic conditions.

KNUCKLE CRANE FOR OFFSHORE(FPSO,DRILL SHIP)
Luffing and folding hydraulic cylinders of pipe handling cranes mounted on marine plants and used for drilling operations are designed and constructed to reflect stringent quality requirements.

MULTI PURPOSE CRANE
It is a crane cylinder that is installed for multiple purposes on warships and coast guard ships. It is used for luffing and boom extension, and is designed and manufactured with an emphasis on corrosion of the marine environment.

TOWER CRANE
The cylinder is installed on the tower crane installed in shipyards and various construction sites. The cylinder is installed vertically, so the main operation is retraction, and it is designed and manufactured in consideration of the installation condition. It is mainly produced by applying rules such as API/ABS.
OFFSHORE MACHINERY

RISER TENSIONER
It is a cylinder installed in the Riser Tensioner, a drilling equipment of a semi-submersible offshore plant, designed and manufactured to withstand corrosion caused by the marine environment.

HULL PART EQUIPMENT FOR FPSO
Hydraulic cylinders installed in Hatch cover, Ramp, and Door of marine plants such as FPSO are designed and manufactured according to the functions of each equipment.

BURNER BOOM
It is a hydraulic cylinder for 90~180 degree rotation of the burner boom installed in drill ships, FPSOs, etc. It is designed to prevent corrosion in the marine environment, and the service life is also specially considered.
SPECIAL SHIP EQUIPMENT

A-FRAME
A-FRAME of 10 to 200 tons is used for underwater drop of working robots such as ROV Launching & Recovery and is intended for use at Sea state level 5 or lower. The cylinder installed in this equipment has various sensors attached to the inside of the cylinder according to the purpose of use and ensures corrosion resistance to maintain stable performance even during long hours of work.

BARGE JACK SYSTEM
It is a cylinder for up and down of the barge jack system used for offshore installation of wind power plants. It is closely related to safety and requires very high quality and reliability, and is designed and manufactured according to the jack-up rule of each classification.

DIVING MOONPOOL
It is a cylinder installed in the Diving Moonpool that is installed on the bottom of the ship so that ROV, PTC, and Diver can get it underwater. making it vulnerable to inflow/corrosion of sea water and is designed and manufactured according to these conditions of use.
WINCH SYSTEM

SPOOLING GEAR SYSTEM FOR HEAVY WINCH
It is a hydraulic cylinder installed in the spooling gear system for the purpose of aligning the wire alignment of 100ton ~ 850ton winch lifting capacity.
It is a high-precision product that maintains the wire tension and holds the winch drum at a constant speed under high load, so it is necessary to maintain the sensor inside the cylinder and the uniform cylinder output.

HYDRAULIIC SPRING UNIT FOR BREAK WINDLASS AND MOORING WINCH
It is a cylinder manufactured for the hydraulic release of Windlace & Mooring winch.
A disc spring is installed inside the cylinder to activate the band brake of the winch by the spring power. For semi-submersible drilling, the winch provides a spring unit for auto tension.
INDUSTRIAL

Hydraulic cylinders for construction equipment and civil engineering equipment
As a hydraulic cylinder used for construction equipment and civil engineering equipment mainly used in special construction methods, it is continuously used for a long time in a high temperature and high pressure environment, so sufficient durability and fatigue deformation are reflected in the design and manufacture.

Hydraulic cylinders for steel equipment and special purpose industrial machinery
It is a hydraulic cylinder supplied to domestic and Japanese steel mills, and is used in harsh environments such as extremely high temperatures and areas where a lot of dust is generated. In addition, it is a cylinder specially designed for vibration and noise of the cylinder itself due to the deflection of the cylinder rod as it requires a stroke distance of 9M or more due to the characteristics of steel equipment.

Telescopic Cylinder
Telescopic cylinders are reflected in equipment that requires long strokes even though the installation space of the cylinder is very narrow or small. It is composed of two types, single action and double action, and is designed and supplied to suit most customer situations.
WATER GATE SYSTEM

Water gate system for water resource management
It is a hydraulic cylinder installed in a water gate system installed for water resources and flood management in rivers. It is specially designed and manufactured for position control sensors and synchronized operation.

STANDING UP BARRIER
It is a hydraulic cylinder installed in the barrier system installed to prevent seawater overflow. It is designed to be strong against corrosion and is specially manufactured for control sensors and synchronized operation.
