Company introduction
Since its establishment in 1986, DONGHYUN (DH HYDRAULIC), a leader in hydraulic equipment with more than 40 years of experience, has export networks not only in Korea but also in more than 40 countries, including the United States, China, and India. In particular, in China, it has offices in Yantai and supplies hydraulic products to various regions in China such as Guangzhou, Nanning, Guizhou, Changjo, Shanghai, Chongqing, Guangxi, and Kunming. The main sales items are all kinds of items related to hydraulic equipment such as pumps, driving motors, swing motors, radial piston motors, joystick/pedal valves, coupling, hydraulic parts, and decelerator parts.
The main pump is responsible for suctioning hydraulic oil from the excavator hydraulic tank, allowing all excavator parts to operate.
Our main pump product is suitable for high-pressure and fixed-capacity piston pumps and can be used as a main pump for excavators, special vehicles, industrial machinery and ship machinery. And the simple pump structure is easy to maintain and repair, and it is durable by using high-quality materials for friction parts.
In addition, they are products that can be used for major excavator equipment such as Hyundai / Doosan / Volvo.
TRAVEL DEVICE / FINAL DEVICE
The final motor is responsible for making the excavator drive using hydraulic pressure.
Our driving motor products have planetary reduction gears that can be controlled from high-speed low-torque to low-speed high-torque, and vice versa. It is used in various fields such as construction, shipbuilding, industrial machinery, and vehicles with special functions.
In addition, they are products that can be used for major excavator equipment such as Hyundai / Doosan / Volvo.
HYDRAULIC PARTS
Cylinder blocks, piston shoe set, set plate, valve plate, shoe plate, ball guide, swash plate, support, spring, etc.
All parts available for major excavator equipment such as Hyundai / Doosan / Volvo / Caterpillar / Hitachi / Komatsu / Kubota / Yamma can be supplied.
SWING MOTOR
Swing motors are axial flow piston motors used for industrial machinery and swings in industrial vehicles.
The swing motor generates rotational force through hydraulic power to rotate the upper structure of the excavator. Typically, an excavator has one or more swing motors, each of which is responsible for rotating the upper structure of the excavator. Different types of motors are used depending on the size and purpose of the excavator.
Our swing motor product is equipped with a mechanical brake relief valve and a makeup valve, so the swing operation of the motor is very smooth. And the design was optimized by properly arranging the motor, brake, and valve to realize high capacity and reliability. The use of a non-impact valve was minimized by absorbing changes in pressure and torque that can occur when the motor stops operating.
They are also available for major excavator equipment such as Hyundai / Doosan / Volvo.
HYDRAULIC MOTOR RADIAL PISTON MOTOR
The radial piston-type low-speed high-torque hydraulic motor is a high-efficiency, low-noise hydraulic motor used in many fields, including injection molding machines, construction machinery, general industrial machinery, and ship machinery.
Our radial piston-type motor product maintains high starting efficiency, can be operated at a wide range of rotational speeds from low speed to high speed, and has no failure and excellent durability.
COUPLING
Coupling is a product to connect the drive shaft and the Middle East shaft, and there are a variety of general-purpose motors, construction machine engines that generate large vibrations and shocks, and machine tools that perform precision control.
They are also available for major excavator equipment such as Hyundai / Doosan / Volvo.
Joystick/Pedal Valve
A pressure-sensitive remote control valve for controlling spools of multiple control valves. Widely applicable to construction and industrial machinery and marine equipment.
Our joystick/pedal valve products are designed to ensure durability and reliability and minimize pressure loss. In addition, it provides excellent responsiveness to even fine movements and guarantees high performance in a wide range of temperatures (-20°C to 90°C).
They are also available for major excavator equipment such as Hyundai / Doosan / Volvo.
REDUCTION PARTS
These are reducer parts such as driving motors/swing motors.
It is a reducer part used in equipment such as Hyundai/ Doosan/ Volvo and boasts excellent quality.
