The vibration source meets all the requirements of modern seismic prospecting, reliability, safety and has high performance. Designed to excite seismic longitudinal waves with a given amplitude and frequency with a peak force of 300,6 кН (67580 lbs) in the geological environment, by mechanical vibration effects on the surface of the soil during seismic exploration.
Applicable scope of the unit is seismic exploration of oil and gas fields, mainly in the northern regions in off-road conditions, virgin snow and wetlands.
The unit is mounted on a self-propelled snow and swamp chassis with a hydrostatic drive. The chassis has a caterpillar thread on rubber caterpillar track and has a high cross in hard-to-reach places, which allows for field work in a variety of geological and climatic conditions and transitional zones, with an ambient temperature of 233 K (minus 40 ° C) to 313 K (plus 40 ° C) and a relative humidity of not more than 80% at 293 K (20 ° C).
