Remote controlled heavy-duty vibration plate, to compress the ground, disengages the eccentric shaft system when the motor speed drops below a level for automatic eccentric shaft adjustments

摘要

To stop the action of a remote controlled vibration plate (1), with its own internal combustion motor, the transmission to the eccentric shaft system (8) is disengaged automatically when the motor speed drops below a given level to allow one or more automatic adjustments to the eccentric shaft system. The eccentric shafts are adjusted by a hydraulic system (12) with a connected accumulator (18). The remote control (16) has a computer (5) with a stored program sequence (17).
