With diverse applications and abundant experience, Hyosung Heavy Industries produces highly reliable products through experienced technical development personnel and various analysis, verification and testing.
Hyosung has started to manufacture wind turbine gear units in response to customer demands for eco-friendly products. Since 2005, Hyosung began wind turbine gear unit production with the 750kW gear box. Hyosung has completed development of the
2MW gear box model and is currently developing the 1.65MW and the 5MW gear box.
Characteristics
Easy maintenance
High gear ratio and power density
Water-pressure type damper (2MW)
Optimized design (gear, shaft, casing)
Highly durable gear with flexible pins (2MW)
Vertical Roller Mill Gear Unit
Vertical Roller Mill Gear Unit
Hyosung’s vertical roller mill gear unit technology is based on the know-how and technical capacity accumulated for the past 20 years and the technical agreement with RENK, and has been supplied to both domestic and international customers. Playing
a key role in the crushing of coal, which is fuel for thermal power plants, and limestone for cement plants, the vertical roller mill gear unit has excellent durability against severe environments and is able to handle high loads. A temperature
sensor is mounted on the vertical roller mill gear unit to monitor temperatures of the bearing and the oil. In addition, a combination of the planetary gear and the bevel gear enables Hyosung to design the reducer with a gear ratio of 20:1-40:1.
Characteristics
Drives the bevel gear and the planetary gear in a straight line in two stages
Welded case without any cracks
Uses a shaft thrust bearing lubricated hydrostatically or hydrodynamically
Applies lubrication and cooling to the gearing and gear bearing according to the isolated oil supply system’s oil pressure.
Jacking System
Jacking System
Hyosung’s Jacking System gear box is a core product of the Jack Up Vessel. Its reduction of the gear ratio ranges from 100:1-20,000:1 or higher and is capable of performing a self-test of loads over 1,200 tons. Therefore, analysis of all parts
and verification of the load test guarantees the best quality under heavy loads.
Characteristics
Various gear reduction ratio: Ranging from 100:1-20,000:1 or higher
Self-test of loads over 1,200 tons
Quick delivery
High durability and excellent quality even with heavy loads
Certified by ABS and CCS
Various supply record since 2006 (440kips, 550kips, 660kips, 750kips, 1000kips)

Marine Gear Unit
Marine Gear Unit
The marine gear units must have higher reliability and durability since their operational conditions are severe. Marine gear units are used for main propulsion, thrusters, dredger pumps, and generator gear boxes. The marine gear unit requires
very complicated and high technology in the design and production stages. In addition, the units must guarantee semi-permanent lifetimes since replacement is not possible after installation.
Characteristics
Design optimized for various customer requirements
Infrastructure for quick delivery and quality warranty
Easy operation and maintenance
High reliability and durability
Cooling Tower Gear Unit
Cooling Tower Gear Unit
Hyosung’s cooling tower gear is used to rotate the blade of the cooling tower. It must have water-proof functionality and it must endure long-term operations. In addition, the direction of the input shaft and the direction of the output shaft
must be at right angles to each other.
Characteristics
Protection class of IP55 or higher
Vertically-upward shaft
Input and output shafts are installed at a right angle
