Patent number: 7410008Abstract: A ground rod driver that uses an industry standard connecting plate to physically attach the driver to Skid Steer type equipment. The driver has a hydraulic, impact driving hammer connected to an alignment beam that enables vertical movement of the hammer. Operation of the driving hammer, as well as up and down motion of the driving hammer is derived from the accessory hydraulic system and connections of the Skid Steer. Simple operating control valves, flow control valve and hydraulic hoses, and an operating station are mounted directly to the driver.Type: GrantFiled: June 2, 2005Date of Patent: August 12, 2008Inventor: Timothy J. Jahnigen

Patent number: 7387173Abstract: A pile driver including an apparatus for allowing relative movement between a hammer and a boom of an excavator. The apparatus includes a mounting plate mounted to the boom that interfits with and is slidable with respect to a frame rail mounted to the hammer. In operation, the hammer is placed on top of a pile and, as the pile is driven downwardly, the hammer follows the pile. Owing to the relative movement between the boom of the excavator and the hammer, the hammer follows the pile without requiring continuous downward readjustment of the boom. In one embodiment, the mounting plate assembly does not extend substantially above the hammer frame. In another embodiment, the hammer can rotate with respect to the boom. In one embodiment, the hammer includes a ram, a cylinder for lifting the ram, and rotation-resistant cable connecting the ram and the cylinder.Type: GrantFiled: March 7, 2006Date of Patent: June 17, 2008Assignee: Innovative Pile Driving Products, LLCInventors: John Jinnings, Mark Gustin

Patent number: 7380611Abstract: A rock drilling machine (1) having, on a machine housing (2), a first attachment element on a first attachment side (13) for its fastening to a slide member which is movable back and forth along a feed beam, the attachment element having a contacting surface (17) for co-operation with a contacting element supported by the slide and a fastening element (18, 19) for the engagement with fasteners co-operating with the slide. The machine is distinguished by the rock drilling machine (1) being provided also with a second attachment element on a second attachment side (15), the second attachment element being configured similarly to the first attachment element, having a contacting surface (17) and fastening element (18, 19), to allow the rock drilling machine (1) to be fastened to the slide member also with the second attachment element. A rock drilling system has the rock drilling machine as one of its components.Type: GrantFiled: January 27, 2006Date of Patent: June 3, 2008Assignee: Atlas Copco Rock Drills ABInventor: Thomas Östling

Patent number: 7198115Abstract: A construction equipment attachment for driving an object, such as a timber piles, steel piles, pipe piles, steel sheet piles, h-beam and the like, is provided. In one embodiment, the attachment includes a hammer slidably coupled to a lead, a lead mounting assembly and a hydraulic actuator coupled to the lead and the lead mounting assembly. The hydraulic actuator is adapted to control the orientation of the lead relative to the lead mounting assembly. In another embodiment, the attachment may be for a self-propelled heavy construction machine. In another embodiment, a self-propelled heavy construction machine having a lead positionable along three axes is provided.Type: GrantFiled: May 6, 2004Date of Patent: April 3, 2007Assignee: Cruz Construction Corp.Inventor: Antonio Cardoso

Patent number: 7052216Abstract: A T-bracket having a pair of spaced apart arms support a housing containing a sprocket wheel and a shaft to turn the sprocket. A handle attached to one end of the shaft turns the sprocket to tighten a chain turning on the sprocket teeth. A flexible wire rod is welded to the T-bracket and is juxtaposed around a rear end of a power drill. The chain is looped around a work piece and attached to a side of the drill opposite from the T-bracket. The handle is turned to tighten the chain and exert force on a drill bit being driven by the power drill.Type: GrantFiled: January 11, 2005Date of Patent: May 30, 2006Inventor: Robert M. Fields

Patent number: 6725946Abstract: An excavation apparatus especially useful when mounted on backhoes and other lighter vehicles used in the construction industry. The excavation apparatus does not require a winch for letting out and retracting its cable nor a reel for storing retracted cable which reduces the weight of the excavation apparatus, lowers its cost while facilitating both operation and servicing. The apparatus has a kelly assembly housing which houses an outer kelly section, and an extendable innermost kelly section adaptable for attachment of a tool. More than one extendable kelly section can be used. A rotary table rotates the kelly sections. A support structure supports the rotary table and the housing. A frame allows the housing to slide relative to the frame in a direction parallel to the axis of the assembly. A downcrowd mechanism, supported by the frame, downcrowds the support structure relative to the frame.Type: GrantFiled: August 27, 2001Date of Patent: April 27, 2004Inventor: Richard L. Howell, Jr.
