The clamping device includes a frame, a first clamp body and a second clamp body that are configured to enable a relative movement, and wherein the first and second clamp bodies are provided with respective first and second clamping surfaces that are configured for engaging with respective first and second flange surfaces, a positioning drive for moving the first clamp body relative to the second clamp body in a positioning direction, and a clamping drive for moving the first clamp body relative to the second clamp body to and/or from the flange surfaces in a clamping direction.

A pile-driver assembly for driving a pile into the ground, preferably offshore, and a method of driving a pile into the ground using the pile-driver assembly is disclosed. The assembly includes a casing defining a chamber, the chamber being configured to house a fluid. The assembly further includes a positioning element configured to position the casing at or on the pile, wherein at least a portion of the positioning element is positioned between the chamber and the pile. The assembly further includes actuating means, wherein actuation of the actuating means displaces the chamber relative to the positioning element, such that the chamber moves away from the pile, and wherein the actuating means is configured to release the chamber for displacement towards the pile such that a force is exerted by the chamber on the positioning member, to controllably drive the pile into the ground.

A pile-driver assembly for driving a pile into the ground is disclosed. The assembly includes a casing defining a chamber configured to house a fluid; a positioning element configured to position the casing at or on the pile; and actuating means. Actuation of the actuating means displaces the chamber relative to the positioning element such that the chamber moves away from the pile to an elevated position. The actuating means is configured to release the chamber from the elevated position for displacement towards the pile such that a force is exerted by the chamber on the positioning member, to controllably drive the pile into the ground. The assembly further includes buffering means, the buffering means being configured to controllably buffer the force exerted by the chamber on the pile as the pile is driven into the ground. The buffering means is configured to rebound the chamber to a rebound position. Further actuation of the actuating means displaces the chamber relative to the positioning element, such that the chamber moves from the rebound position to the elevated position. A control system for controlling the pile-driver assembly and a method of driving a pile into ground using the pile-driver assembly are also disclosed.

A civil engineering device, in particular a pile-driving or drilling device, has at least one positioner, in particular a working carriage for accommodating an implement, connected with a carrier device by relatively movable links within a kinematic chain and connected by joints and/or linear adjusters and with at least six actuators for changing their corresponding position and/or orientation, and with a control and regulation device for controlling them. The control and regulation device has an input module for specifying a positioner target position, and is connected with a computer module that determines at least one displacement path for moving the positioner from its current (starting) position to the target position, and, using inverse kinematics, the locations of the individual actuators required for implementing the path, and sends these locations to the control and regulation device to control the actuators. A method multi-dimensionally, free positions a civil engineering device positioner.

An alignment and installation jig for a screw anchor driving machine. The alignment and installation jig includes a laser target that can be moved from an alignment position to a driving position. The jig may also include one or more automated crimping assemblies to form permanent connections between overlapping foundation components while the machine is correctly oriented.

A mechanical hammer that includes a support and an elongated member. The support defines a linear guide track. The elongated member is laterally confined by the support while being movable back and forth along the linear guide track between an extended position extending from the support and a retracted position relatively retracted within the support. A rack and pinion drive assembly is provided to selectively drive the elongated member along the linear guide track.

An apparatus for driving a pile section having a central opening into the ground includes a mast attachment with roped hydraulic cylinders, a high frequency hydraulic impact hammer connected with the mast, and a drive cap. The mast with roped hydraulic cylinders provides for vertical movement of the high frequency hydraulic impact hammer, and the drive cap connects with the high frequency hydraulic impact hammer and a pile section to transfer the drive force of the hammer to the pile section. When the mast is connected with an excavator and the drive cap is connected with the high frequency hydraulic impact hammer, a pile section is connected with the drive cap lower end and the high frequency hydraulic impact hammer is operated to drive the pile section into the ground. A system for driving piles into the ground includes an excavator, an apparatus connected with the excavator, and a plurality of base pile sections. The pile sections have an upper end surface containing a central opening which connects with the apparatus prior to driving the pile sections into the ground. The apparatus includes a mast with roped hydraulic cylinders, a high frequency hydraulic impact hammer connected with the mast, and a drive cap. The mast with roped hydraulic cylinders provides for vertical movement of the high frequency hydraulic impact hammer, and the drive cap connects with the high frequency hydraulic impact hammer and a pile section to transfer the drive force of the hammer to the pile section.
