Title (EN) MOBILE HIGH FREQUENCY VIBRATOR SYSTEM
(FR) SYSTEME VIBRATEUR A HAUTE FREQUENCE, MOBILE
Abstract: front page image
(EN)A carrier mounted seismic vibrator system that is primarily adapted for generation of high force, high frequency seismic energy into an earth medium. The apparatus includes first and second vibrators (12F and R) as supported by first and second lift systems (28F and R) disposed in tandem juxtaposition generally centrally in said vehicle (10), and the lift systems (28F and R) are designed to maintain equal holddown force on the vibrator coupling baseplates (32F and R) without exceeding the weight of the carrier vehicle. The juxtaposed vibrators are then energized in synchronised relationship to propagate increased amounts of higher frequency seismic energy into an earth medium.
(FR)Un systeme vibrateur sismique monte sur un vehicule transporteur est adapte essentiellement pour produire une energie sismique de grande intensite et de haute frequence dans un milieu terrestre L"appareil comprend un premier et un second vibrateurs (12F et R) supportes par un premier et un second systemes de levage (28FR) disposes en tandem au centre dudit vehicule (10), et les systemes de levage (28F et R) sont concus pour maintenir une force d"assujettissement egale sur les plaques de base d"accouplement des vibrateurs (32FR) sans depasser le poids du vehicule transporteur. Les vibrateurs juxtaposes sont ensuite excites en synchronisation pour propager des quantites accrues d"energie sismique de frequence plus elevee dans un milieu terrestre.
