Vibration ramming arrangement and method for operating the vibration ram assembly

摘要

The invention relates to a vibration ram arrangement comprising a hydraulic unit (1), a vibrator (2) which is connected to the hydraulic unit (1) via hydraulic hoses (3) and a controller (S) assigned to the hydraulic unit (1), wherein the hydraulic unit (1 ) has a hydraulic pump (6) driven by an internal combustion engine (5), the vibrator (2) having imbalances (11) and an adjustable hydraulic motor (2) driving the imbalances (11) and a hydraulic fluid being supplied by the hydraulic unit (1) , the hydraulic hoses (3) and the hydraulic motor (10) is circulated. According to the invention, the vibrator (2) has a device (12) independent of the control (S) for the automatic adjustment of a displacement volume of the hydraulic motor (10) as a function of a pressure within the circuit, wherein a frequency sensor (14) for determining the frequency of the vibrator (2) to the controller (S) is connected and wherein the controller (S) is adapted to control a guided through the circuit flow in dependence on the signal of the frequency sensor (14).
