Hydraulic Top Bracing
HANMI HYDRAULIC MACHINERY CO., LTD.
Hydraulic top bracing is an attenuation device installed between the main engine and the hull of the ship to reduce thermal expansion and vibration from the main engine to natural frequencies. The operating principle is an automatic control operating system through in/out and on/off the operating range of the hydraulic top bracing according to the rpm of the main engine.
The number of hydraulic cylinders per engine is typically 2, 4, 6 depending on the type of engine, up to 8 are installed if necessary, and 1~2 of control panels are installed.

Cylinder Lubricating Pump - WIN GD
HANMI HYDRAULIC MACHINERY CO., LTD.
This system product is a product that directly supplies and heats lubricant oil for smooth operation of the main engine cylinder’s metallic and mechanical movement.
Lubricator, a product that supplies lubrication directly to the main engine cylinder liner, can control injection timing and consumption using an electronic control method that responds to the movement of the main engine piston. The alpha lubricator system is based on an algorithm controlling the cylinder oil dosage proportionally to the sulphur content in the fuel and, fuel consumption on particular load of engine. Minimum cylinder oil dosage is required to provide an adequate oil film and detergency properties.
Everllence and WIN GD engines are currently applying the second generation Lubricator type, the Everllence type is Mk-I and the WIN GD type is Mk-ε (Epsilon).
