Durable Actuation for Punishing Job Sites #
Construction equipment operates in extreme climates, heavy dust and intense vibration, where stability determines whether a project stays on schedule. ASHUN provides custom hydraulic cylinders and high-torque rotary actuators for excavators, loaders and heavy construction vehicles, emphasizing anti-side-load capability and precision under continuous high-pressure operation.

Industry Challenges #
- Harsh environmental corrosion — Prolonged exposure to mud, gravel and extreme weather accelerates seal wear and cylinder corrosion, leading to unscheduled downtime.
- Severe vibration and impact loads — Crushing and excavating generate large shock loads; insufficient anti-side-load capacity can cause internal deformation, scoring or structural failure.
- Precision control in confined spaces — Urban construction requires maneuverability, while traditional linear cylinders struggle to provide flexible, high-torque, multi-angle articulation.
- High-pressure continuous loading — Tight schedules demand around-the-clock high-pressure operation; internal leakage or torque degradation reduces project efficiency.
Product Characteristics #
- Reinforced anti-side-load structure — Structural integrity is engineered to absorb shock loads and extend cylinder life under severe duty cycles.
- Stable high-torque rotary control — Rotary actuators offer a compact footprint with consistent torque and precise angle control for tiltrotators, grapples and steering.
- Advanced surface protection — Sealing configurations and surface treatments resist mud, dust and gravel ingress.
- Optimized leakage prevention — Manufacturing quality assurance minimizes internal leakage under high loads, reducing unexpected maintenance costs.
