Benefits of technology

"The present invention is a modular vibratory pile driver system that can be used to drive different types of piles with a single base unit. The system includes a housing, vibratory gear case, and mounting base, as well as interchangeable gripping assemblies for different pile profiles. The system also includes a set of jaws that can grip a pile from two different locations, and a set of removable pivot arms that can be attached to the jaws. The system reduces costs and saves time by eliminating the need for multiple pile drivers and facilitates centering of the pile with the driver for more efficient energy transfer. The system also allows for easy interchange of the gripping assemblies for different pile profiles."

Problems solved by technology

Current side grip vibratory pile drivers have the disadvantage that they are designed for driving only one type of pile.
This leads to significant increased cost at a job site and requires that the construction company inventory more than type of pile driver for use at its various job sites.

Embodiment Construction

[0031]Referring now to FIGS. 1-5, modular vibratory side grip pile driver 30 is shown and generally includes housing 31, first assembly 35, and jaw assembly 50. Pile driver 30 may be used to grasp and drive sheet or beam, e.g., I-beam and H-beam, pile 33 into the ground. Housing 31 includes vibratory gear case 36 and mounting base 37. Bracket 41 connects housing 31 to attachment assembly 32 which is used to attach pile driver 30 to an excavator or other suitable construction machine for mounting pile driver 30 thereon. Rotational connector 38 is provided along with attachment plate 32 to permit rotation of housing 31 relative to the excavator. Rubber insulators 34 are included on the inner portions of housing 31 to reduce vibration caused by gear case 36 during use of pile driver 30 and to prevent such vibration from vibrating a portion of the excavator. Pile driver 30 is a modification of the Model SPM 15 vibratory pile driver manufactured by Hercules Machinery Corporation of Fort ...

Abstract

A modular side grip vibratory pile driver system having a housing, a vibratory gear case and a pair of jaws adapted to grip a variety of pile profiles. The housing is rotatably connected to a construction machine such that the jaws can be moved from a position wherein the jaws are oriented vertically and spaced apart horizontally to a position wherein the jaws are oriented horizontally and spaced apart vertically. A plurality of sets of gripping assemblies having different gripping profiles are interchangeably connected to the jaws.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under Title 35, U.S.C. §119(e) of U.S. Provisional Application Ser. No. 60 / 943,979, entitled MODULAR VIBRATORY PILE DRIVER, filed on Jun. 14, 2007.BACKGROUND[0002]1. Field of the Disclosure[0003]The present disclosure relates to pile driving equipment. More particularly, the present disclosure relates to a modular vibratory side grip pile driver system and method for assembly.[0004]2. Description of the Related Art[0005]Vibratory pile drivers are used in a plurality of applications to drive pile, such as sheet pile, pipes, I-beams, H-beams, and poles, for example, into the ground. The pile driver may be mounted on an excavator and include articulating arms and side-gripping jaws to facilitate the pile driving process.[0006]Current side grip vibratory pile drivers have the disadvantage that they are designed for driving only one type of pile. Therefore, if it is desired to switch from driving sheet pile ...
