Seismic sources
Weight dropper FFWD-GX II
Free fall of a 360 kg hammer from a height of 4 m with a tool assembled on an IVECO Daily truck.
The tool is equipped with a locking mechanism preventing the rebound of the weight when it hits the base plate.
Under favourable conditions investigation depths reached 4500m.
Weight dropper BISON EWG III
The fall of a 250 kg steel piston is accelerated by elastic rubber slings. The drop height is 0.8 m. The tool is assembled on a 4×4 GAZ truck.
Under favourable conditions investigation depths reached 3000m.
Weight dropper VAKIMPAK
The weight is a 50 kg hammer connected to an anvil in an airtight cylinder. The fall is accelerated by the vacuum produced when the hammer is lifted. The drop height is 1.6m, the total weight is 750 kg.
Under favourable conditions investigation depths reached 900m.
Weight droppper SAWD
The weight of 15 kg is accelerated by a spring. The SAWD is equipped with a small hydraulic weight lifting unit driven by an electric motor. In order to save battery power the lifting of the weight can be assisted manually. Very handy in rough terrain, the total weight is 150 kg.
