Variable-Load Duty  |  Excavators, Loaders, Cranes

El punto débil

Excavators, loaders, bulldozers, and cranes face highly variable loads — hydraulic pump pulsation and engine order excitation stack together, creating torsional peaks that fatigue the crankshaft and amplify hydraulic ripple. Add extreme ambient temperatures, dust, and shock loading, and the damper’s job becomes critical. A failure in the field stops an entire crew.

Solución Auramaia

We supply silicone-oil and composite dampers tuned for variable-load off-highway duty. Broadband viscous damping absorbs torsional energy across fluctuating RPM and load conditions. For extreme-duty applications, composite designs add tuned spring elements for precise frequency targeting. All units are built to withstand high ambient heat, vibration, and contaminant exposure.
