100T-240T Mining Haul Trucks · Hydro-Pneumatic
Heavy Equipment Suspension Struts
Massive front and rear hydro-pneumatic suspension cylinders built for extreme axle loads and severe haul-road operating conditions.
Mining dump truck suspension struts bear extreme payload weights and violent dynamic forces during shovel loading and rough terrain hauling. Combining oil damping with nitrogen cushioning, they provide stable ride dynamics and chassis protection.
100T-240T Mining Haul Trucks · Hydro-PneumaticEngineering detail
Custom engineered & quality-tested in-house.
AB Hydromatics manufactures and re-engineers suspension cylinders featuring induction-hardened chrome rods, massive spherical bearing spherical eye mounts, and multi-stage damping orifices, tested on our custom suspension test benches.
Engineering Highlights
- Calibrated on dedicated suspension testing benches to ensure exact damping rates
- Reinforced heavy-wall forged cylinder barrels resist side-load bending moments
- Severe-duty multi-lip seal pack prevents oil-gas cross contamination
- Compatible with major global mining haul trucks (CAT, Komatsu, BEML, Belaz)
