Solutions

Construction Machinery

Construction equipment operates in punishing environments characterized by extreme climates, heavy dust, and intense vibration. Equipment stability is the ultimate key to maintaining project schedules. ASHUN provides highly durable custom hydraulic cylinders and high-torque rotary actuators specifically engineered for excavators, loaders, and heavy-duty construction vehicles. Our solutions feature superior anti-side-load capabilities and extreme precision, ensuring flawless performance under heavy loads, high pressure, and continuous operation—conquering the toughest job site challenges.

Lifting Equipment

Material handling equipment carries extreme risks to human safety and valuable assets; every lift and rotation must be flawless. For aerial work platforms (AWPs), cranes, tail lifts, and jacking systems, ASHUN delivers custom hydraulic cylinders integrated with fail-safe mechanisms and rotary actuators for high-precision positioning. We guarantee smooth, zero-leakage performance under heavy aerial loads and high-frequency lifting conditions.

Military and Aerospace

In defense and aerospace applications, mission success is paramount, and hydraulic system failures are strictly zero-tolerance. Certified by the AS9100 Aerospace Quality Management System, ASHUN provides custom hydraulic cylinders and high-torque rotary actuators engineered with exceptional safety factors for armored vehicles, radar antennas, and ground support equipment (GSE).

Agricultural Machinery

From soil preparation to harvesting, agricultural machinery is constantly exposed to mud, dust, and erratic weather. ASHUN provides weather-resistant, leak-proof custom cylinders and precision rotary actuators for tractors, combine harvesters, and diverse attachments. Our high-load capacity ensures uninterrupted, high-efficiency operation during critical farming seasons.

Smart Automation/Industry 4.0 or Robotics Industry

In the era of smart manufacturing, heavy robotics and automated equipment require actuation that combines high power density with precise data feedback. ASHUN empowers heavy-duty robotic arms, AGVs, and automated production lines with smart-sensor-integrated cylinders and high-precision rotary actuators, seamlessly bridging the gap between traditional hydraulics and Industry 4.0 servo-hydraulics.
