ABSTRACT:
A vibration generator for a vibration pile driver has imbalance masses that can rotate and which are disposed on shafts. The rotational position of the imbalance masses can be adjusted relative to one another. A control and regulation circuit is provided which has a memory unit for storing ground composition data sets or task-specific default data sets with defined operational characteristic variables. The unit also has sensors for continuous detection of the defined operational characteristic variables, an evaluation unit for comparing the operational characteristic variables that are determined with the operational characteristic variables of the selected default data set, a regulation device for regulating the vibration generator, and a control device for controlling the adjustment of the rotational position of the imbalance masses relative to one another. The vibration generator is part of a vibration pile driver.
