AWD-33PS is a variant of seismic source of the “weight drop” type. The hammer is equipped with an inclined platform, allowing it to be installed at an angle of 45 degrees, and a special stop, adding stability in an upright position, what allows to perform survey on shear waves.
The striking mass (hammer) is accelerated with the aid of massive stretching springs that are armed by means of an electric winch powered by a car battery (65–180 A/h). The minimum period of operation of the source is 3 s.
The source AWD-33PS is mounted on a compact lightweight frame equipped with reliable wheel blocks. The delivery package of the source includes one hammer: 10, 20 or 33 kg. Hammers of another weights can be supplied additionally. The design of device allows hammer’s fast replacing in the field. The source can be used on a rugged terrain. The total weight of the source with a battery pack and a 33 kg hammer is less than 100 kg. The energy of a single impact reaches 600 J.
It is possible to develop fastenings for a car, ATV, cross-country vehicle or any other transport.
