Ho-Pac Hydraulic Vibratory Technology
At the core of the VMV 818 is proven Ho-Pac vibratory technology, integrated into Viking's engineered platform to deliver dependable performance in demanding marine and foundation applications. The system provides smooth, controlled vibration for efficient pile installation while helping reduce unnecessary stress on the carrier machine.
Whether driving sheet pile, H-beam, timber, pipe casing, or vinyl piles, the VMV 818 combines consistent vibratory force with precise hydraulic control to maximize productivity across a wide range of soil conditions. Paired with Viking's American-built frame, hydraulic system, and factory-direct support, the result is a durable, contractor-focused pile-driving solution built for everyday production.

VMV 818 FAQ
What The Crew Needs Confirmed Before Mobilization
Five practical questions to settle before the VMV 818 is configured, quoted, and sent to the job.
When should I move up from a compact model?
Move up when a compact system cannot maintain the required production rate, control the intended pile profile, or deliver reliable extraction across the expected ground conditions.
Which jobs are the best fit?
Marine, foundation, utility, retaining, and civil scopes that demand repeat pile driving and extraction are the strongest fit—especially where carrier mobility and access remain critical.
Can one clamp cover every pile?
No. Pile width, profile, wall thickness, material, handling load, and required grip determine the correct clamp or jaw configuration. Viking confirms the interface before quoting.
What must be confirmed on the carrier?
Pump flow, operating pressure, return pressure, case-drain routing, hose and coupler capacity, hydraulic mode, lift chart, stability, attachment weight, and working radius must agree with the application.
What should I send with a quote request?
Send the excavator make and model, auxiliary hydraulic data, pile profile and dimensions, soil or job conditions, working radius, project location, and schedule. Complete technical inputs produce a faster, cleaner machine match.
