マニホールドを球面軸受を介してケーシングに支持して
なる油圧ドロップハンマ。In a hydraulic drop hammer that strikes a pile by raising and dropping a weight using a hydraulic cylinder within a casing with a soundproof structure, an outer cylinder that fits onto the cylinder cylinder of a double-rod type hydraulic cylinder is provided, and the cylinder cylinder and the outer cylinder are connected to each other. A manifold is integrally molded and connected to a manifold having a built-in control circuit that connects and blocks communication between the upper cylinder chamber and the lower cylinder chamber, and forms a flow path communicating between the cylinder and the upper cylinder chamber and the lower cylinder chamber, respectively. The hydraulic drop hammer becomes supported on the casing via a spherical bearing.
