Abstract

The present invention is directed to a pile driver with a lead that is capable of receiving and supporting a pile in a substantially horizontal orientation and subsequently rotating the lead and received pile from the substantially horizontal orientation to a substantially vertical orientation needed before the pile can be driven into the earth. In one embodiment of the pile driver, the chassis is of a relatively short length to be more maneuverable and the lead is capable of supporting a long and/or quite massive pile. To prevent the chassis, lead, and pile from tipping or being placed in an unstable condition, the pile driver further comprises a movable counterweight system. The method is also directed to methods of using such a pile driver to accomplish the driving of a pile.

Abstract

The present invention is directed to a precast girder that is used as the outer-most lateral girder in a bridge superstructure. In one embodiment, the girder is comprised of a first flange, a second flange that is separated from the first flange, and a web that connects the first flange to the second flange so that the resulting combination of the first flange, second flange, and web generally has an I-beam cross-section. The girder further includes an edge portion that is connected to the second flange and extends away from the first and second flanges.

Abstract

The present invention is directed to an apparatus for use in constructing a bridge comprised of a superstructure and a substructure that supports the superstructure and is comprised of foundations and piers. In one embodiment, the apparatus is comprised of a truss structure, a trolley that is supported by the truss structure and used to move materials used to build the bridge along at least a portion of the truss, a support structure for supporting the truss structure, and rotatable lead that can receive a substructure related element from the trolley and be used to rotate the element to a desired position to further the construction of the bridge.
