ABSTRACT:
An over-the-road type vehicle for transport and powering of a seismic hydraulic vibrator which is adapted to operate in either one of two modes of operation. A first mode is the conventional mode wherein the vehicle is operated over large distances at varying road speeds, obtained by use of multiple gear ratios, and varying engine speeds. The second mode of operation is in a single value of road speed, with engine under control of a governor, to operate at constant high speed, and the movement of the vehicle is by successive short traverses at constant speed. In this second mode of operation the single engine alternately powers the hydraulic vibrator, and with the engine still at high speed, then moves the vehicle to a new vibration point a short distance away. A high energy efficiency is provided by the use of a mechanical, rather than hydraulic drive system, and a high time efficiency is provided by a novel style of clutch that can start the vehicle from rest with the engine at maximum speed.
