A hydraulic drive of element of a water lock

PONAR Wadowice developed and manufactured hydraulic drives of gates and bars of the modernized chamber of the North Łabędy Lock at the Gliwicki Canal. The supply included 4 pieces of hydraulic power packs, 4 accumulator stations and 12 hydraulic cylinders.

A hydraulic drive of element of a water lock

The lock works in an automatic mode, that is why the power packs are equipped in electrically controlled directional control valves, pressure sensors, oil lever monitors and temperature sensors allowing for automated work of the hydraulic power pack. The developed solution for providing motion of the emergency gates and bars uses hydraulic accumulators. The hydraulic energy in the accumulators allows for closing the lock in case of a power failure.
