    摘要： The present invention relates to a pile-driver, comprising a support member arranged or arrangeable in transverse direction at or on a pile, a liquid chamber which is bounded on the underside by the support member and which further comprises one or more side walls and is configured to receive a liquid therein, one or more pressure build-up chambers, an ignition mechanism configured to ignite a fuel present in the combustion space, and wherein the combustion space is configured to expand fuel present therein during combustion such that a pressure build-up takes place above the support member and the liquid present above the support member in the liquid chamber is displaced at least in upward direction away from the support member, whereby a downward force is exerted on the pile via the support member. The invention further relates to a method for driving a pile downward into the ground using such a pile-driver.

    摘要： A pile driving ram for driving piles into subaqueous ground, during which a heavy piston operating as a hammer is each time lifted by fuel explosion in a cylinder, comprises a considerable and expensive cylinder piece, which has inlet and outlet ports and which comprises at least two guide girdles for supporting guide members co-operating with at least one guide stay of a guide frame. In order to increase the lifetime of the cylinder piece, the core is moulded from precious steel according to the fling moulding method.

    摘要： A pile hammer includes a cylinder, a piston displaceably guided in the cylinder, and a striker displaceably guided in the cylinder. The striker is disposed underneath the piston in the operating position of the pile hammer. A combustion chamber is delimited axially by a face surface of the striker that lies in the interior of the cylinder and by a face surface of the piston. Using at least one fuel feed device a predetermined amount of fuel can be introduced into the combustion chamber during each working cycle. A primary fuel feed device is provided, which includes a primary fuel nozzle connected with a primary fuel tank having a fuel with great anti-knock properties. The primary fuel nozzle is structured as a high-pressure injection nozzle. An ignition oil feed device is also provided, which includes an ignition oil nozzle connected with an ignition oil tank having an ignition oil. The ignition oil nozzle is structured as a low-pressure injection nozzle. A method operates such a pile hammer.

    摘要： A cylinder piece for use as the cylinder in a pile driving ram is provided with inlet and outlet ports and at least two guide girdles for supporting guide members adapted to cooperate with at least one guide stay of the guide frame. The core of the cylinder piece is made by forging and has at least two substantially cylindrical guide girdle faces for guide girdles, with the guide girdle being formed by a ring having a cylindrical bore being shrunk around a guide girdle face.
