Abstract

A seismic source includes a seismic energy generating assembly (22) having an impulse generator (28) provided with a relatively large bottom (162) which, in use, is seated down flush against the earth surface. This provides a relatively large area of firm contact with the earth surface for transmitting powerful impulses generated by the generator (28) into the earth. The generator is mounted on a pivoted elevator including an outer supporting frame (23) mounted on a land vehicle, upright parallel channel members (64, 66) for guiding the generator in vertical movement relative to the outer supporting frame, the channel members (64, 66) being pivotally mounted by bearing assemblies (29) to the outer supporting frame (23) for swinging movement about a generally horizontal axis (63) extending transversely with respect to the vehicle. Hydraulic cylinders (134, 136) lift the generator relative to the channel members from an operating position in contact with the ground to a raised position above the ground in readiness for transport. <IMAGE>
