Vibration ramming arrangement and method for operating the vibration ram assembly

摘要

Vibratory ram assembly comprising a hydraulic unit (1), a vibrator (2) spatially separated from the hydraulic unit (1) and connected via hydraulic hoses (3) to the hydraulic unit (1) and the hydraulic unit (1) associated with control (S), wherein the hydraulic unit (1) comprises an internal combustion engine (5) and a hydraulic pump (6) driven by the internal combustion engine (5), wherein the vibrator (2) comprises rotatably mounted imbalances (11) and at least one adjustable variable displacement hydraulic motor (10) Having drive of the imbalances (11) and wherein a hydraulic fluid through the hydraulic unit (1), the hydraulic hoses (3) and the at least one hydraulic motor (10) is circulated, characterized in that the vibrator (2) one of the controller (S) independent means (12) for adjusting the displacement of the hydraulic motor (10) in response to a pressure within the circuit and that a frequency sensor (14) for determining the frequency of the vibrator (2) to the controller (S) is connected, wherein the controller (S) is adapted to the guided through the circulation volume flow in response to the signal of the frequency sensor (14 ) to control.
