OVR VM Series
Amplitude/eccentric moment can be easily adjusted from minimum to maximum using a variable motor
The OVR VM Series is specifically engineered for efficient pile driving and extraction operations across a wide range of soil conditions. The advanced variable moment (phase shifter) technology of the OVR Variable Moment Vibratory Hammers minimizes resonance by automatically adjusting the eccentric moment during the start and stop phases of the vibration cycle inside the gearbox housing.
As a result, the vibration system delivers high performance and operational stability while significantly reducing vibration transfer to surrounding structures and soil.
• Advanced variable moment technology
• Reduced vibration impact on nearby structures
• Resonance-free start and stop operation
• Adjustable amplitude for different soil conditions
• High efficiency and stable performance
• Durable, powerful, and long-lasting construction
