The invention relates to a construction device and to a method for operating this construction device, comprising a carrier device, an approximately vertical mast, which is mounted on the carrier device, a movement element, which is vertically movable along a linear guide on the mast, and at least one GPS receiving unit, which is arranged in the region of the mast. According to the invention, it is provided that the at least one GPS receiving unit is attached to the movement element and that the at least one GPS receiving unit can be moved between an upper, first measuring position and a lower, second measuring position by means of the movement element.

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.

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, a coupler rod, a conversion housing, a hydraulic actuator, and a ram connector. The hydraulic actuator defines an actuator rod, a lifting head, and a lift connector. The lifting head defines an upper wall and a lower wall. The lift connector attaches the actuator rod to the upper wall of the lifting head. The ram connector attaches the coupler rod to the lower wall of the lifting head. Operation of the hydraulic actuator raises and lowers the ram to strike the pile.

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.

A rope-suspended leader mast includes a lower part for accommodating a material to be pile-driven and an upper part for accommodating a diesel pile driver having a fuel feed. The leader mast is provided with at least one securing rope. A fuel feed interrupter interrupts the fuel feed of the diesel pile driver accommodated by the rope-suspended leader mast when the securing rope is tensioned.

An air-operated hammer, comprising a hollow ram; a frame; an air cylinder and piston assembly disposed within the ram, wherein a top of the cylinder and piston assembly is attached to a top of the frame and wherein a piston rod of the cylinder and piston assembly is attached to a bottom of the ram; an air flow control valve mounted on and in fluid communication with a manifold disposed on a top of the frame; a first pressurized air reservoir comprising a first flexible hose of a first size attached to an outside surface of the frame, wherein lifting of the ram is caused by pressurized air from the pressurized air reservoir being supplied to and entering a bottom of the cylinder, wherein pressurized air entering a bottom portion of the cylinder causes the piston to raise the ram.
