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 to assembly a truss foundation. One crimping assembly device may effect crimp joints between a foundation component held by the jig and overlapping upper ends of a pair of adjacent foundation legs. Second crimping assemblies may telescope down each leg to effect respective crimp joints between the lower end of the leg and the upper end of a driven foundation component.

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.

A pile-driver assembly for driving a pile into the ground, preferably off- shore, and a method of driving a pile into the ground using the pile-driver assembly is dis- closed. The assembly includes a casing defining a chamber, the chamber being configured to house a fluid, the chamber comprising a channel extending at least partially therethrough. 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, wherein the positioning element comprises a guide element, configured to extend at least partially through the channel of the chamber. 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.

The present disclosure relates to a vibro-hammer 1 connected to heavy construction equipment, and more particularly, a vibro-hammer 1 having a side grip in which vibrations are prevented from being transmitted to a connected heavy equipment machine to avoid a problem such as a change in a perforation position, the vibro-hammer 1 is firmly connected to a perforated pile to transmit vibrations generated in a gear box to the perforated pile through the side grip and improve workability, arms are gear-coupled to each other to prevent the arms and the side grip from being released from each other due to frequent vibrations, a pair of arms and the side grip can come into close contact with the perforated pile or separated from the performed pile by a single cylinder, the side grip can be easily replaced according a shape of the perforated pile, and applicability and workability is improved.
