Heavy-wall cylinder engineered for construction equipment vibration resistance, featuring 30% thicker tube walls compared to standard ISO cylinders. The chrome-silicon alloy piston rod withstands lateral forces common in excavator bucket linkages. Integrated shock absorbers reduce end-impact by 40% at maximum operating pressure.
- Excavator bucket positioning mechanisms
- Concrete pump truck boom articulation
- Pile driver impact dampening systems
- Crane outrigger pressure balancing
- Rock crusher jaw plate adjustment
Installation Protocol:
Requires vibration-damping mounts (5Nm torque limit on flange bolts).
For vertical installations, use rod-down orientation with 200mm minimum
rod clearance. Lubricate through air supply with ISO VG32 oil mist
(1/3000 oil-air ratio) if non-lubricated operation is needed.
