A vibrator assembly comprising a feed pipe that has a longitudinal axis as well as a first end and a second end. The vibrator assembly may further comprise a vibrator unit that is mechanically coupled to the feed pipe, and a filling assembly which extends into the feed pipe at the first end and is designed to pick up material and direct same into the feed pipe. The feed pipe may have at least two separate channels from the first end to the second end and parallel to the longitudinal axis.

A shock absorbing apparatus (suppressor) for a vibratory pile driver includes three suppressor sections, including a first section adapted and arranged to absorb a load up to a selected amount. A second suppressor section is adapted to absorb a load above the first shock-absorbing section, with a third suppressor system providing a transition between first and second suppressor action as load increases.

A bearing cooling system for a vibratory pile driving system comprising at least one housing wall defining at least one bearing opening and at least one bearing assembly supported by the at least one housing wall in the at least one bearing opening. The bearing cooling system comprises a bearing cover plate, a bearing cover seal member, and at least one bearing bolt. The bearing cover plate defines an inner surface having a bearing cover plate seal recess. The bearing cover seal member adapted to be received at least partly within the bearing cover plate seal recess. The at least one bearing bolt is configured to secure the bearing cover plate relative to the at least one housing wall to form at least one contact location at which the bearing cover plate is in contact with at least a portion of the at least one bearing assembly.

The invention relates to a method for operating a vibrating ram arrangement comprising a hydraulic assembly with a hydraulic pump driven by an internal combustion engine, a vibrator connected to the hydraulic assembly in a hydraulic circuit, a hydraulic clamping device connected to the vibrator for a material to be rammed, and a controller, with which a fluid flow through a hydraulic motor of the vibrator can be activated and deactivated and with which the hydraulic clamping device can be closed and opened. According to the invention, the controller requests at least one operating state value during a pause in the operation when the vibrator is deactivated and automatically stops the internal combustion engine if the operating state value corresponds to a specified value. Additionally, the controller automatically starts the internal combustion engine in order to resume the vibrating ram operation in the event of a user signal.
