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.

Embodiments of the present disclosure generally relate to a pumping unit base and methods for operating with the pumping unit base. The pumping unit base may include a plurality of driven piles installed in the ground, and a metal platform fixedly attached to the plurality of driven piles, wherein the metal platform is positioned above the ground. The metal platform may be removed from the driven piles and reinstalled to the driven piles.

A hydraulic impact hammer for striking a pile has a main housing, a ram supported for movement within the main housing, a coupler rod detachably attached to the ram, a conversion housing detachably attached to the main housing, a hydraulic actuator supported by the conversion housing, the hydraulic actuator defining an actuator rod, a lifting head, a lift connector, and a ram connector. The lift connector is detachably attaches the actuator rod to the lifting head. The ram connector detachably attaches the coupler rod to the lifting head. Operation of the hydraulic actuator raises and lowers the ram to strike the pile.

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 work cycle. An end ring is disposed on the cylinder for forming a capture groove. The piston is provided with a step that projects outward, which makes contact with the capture groove in the upper end position of the piston, and the end ring is elastically connected with the cylinder.

A guide system for allowing a diesel hammer to be supported by a plurality of support systems comprises a primary channel system and a pair of first and second channel adapter assemblies. The primary channel system rigidly connected to the diesel hammer to define a pair of primary channels and a primary spacing distance. Each first channel adapter assembly defines a first secondary channel. The guide system operates in a first configuration and a second configuration. In the second configuration, each of the first channel adapter assemblies is detachably attached to the primary channel system such that the first channel adapter assemblies define a first secondary spacing distance between the first secondary channels, the first secondary spacing distance is different from the primary spacing distance, and portions of a second support system of the plurality of support systems are received within the first secondary channels.
