Excavator Hammer Attachment Apparatus

Abstract

The excavator hammer attachment apparatus is adapted to be quickly attached to an excavator or skid-steer loader arm and used in easily and quickly demolishing concrete by swinging the apparatus and striking the concrete. Because the apparatus employs rubber isolators instead metal springs, such demolition is able to be accomplished with less noise and shock to the machine to which it is attached than would otherwise occur and with substantially improved operator safety.

I claim: 
     
         1 . A excavator attachment apparatus for use in demolishing concrete and like objects by attaching said apparatus to an excavator arm and swinging said apparatus into said concrete or like object, said apparatus comprising a hammer device and a mount bracket, wherein said hammer device is connected to said mount bracket by a pivotable hinge joint and by at least one flexible elastomeric member. 
     
     
         2 . The apparatus of  claim 1 , wherein said mount bracket is connected to an arm of at least one of an excavator and a skid-steer loader. 
     
     
         3 . The apparatus of  claim 1 , wherein said hammer defines a single weldment. 
     
     
         4 . The apparatus of  claim 1 , wherein said wherein said apparatus has a mass of at least one of 200 pounds, 350 pounds, 500 pounds, 750 pounds, 1,000 pounds, 1,500 pounds, 2,000 pounds, 3,000 pounds, and 5,000 pounds. 
     
     
         5 . The apparatus of  claim 1 , wherein said hammer includes a hammer head, and wherein said hammer is adapted such that said hammer head is readily replaceable with an alternate hammer head. 
     
     
         6 . The apparatus of  claim 1 , wherein said flexible elastomeric member defines a rubber isolator. 
     
     
         7 . The apparatus of  claim 1 , wherein said mount bracket includes a protective screen connected thereto. 
     
     
         8 . A excavator attachment apparatus for use in demolishing concrete and like objects by attaching said apparatus to an excavator arm and swinging said apparatus into said concrete or like object, said apparatus comprising a hammer device and a mount bracket, wherein said hammer device is connected to said mount bracket by a pivotable hinge joint and by at least one flexible elastomeric member, and wherein said mount bracket is connected to an arm of at least one of an excavator and a skid-steer loader. 
     
     
         9 . The apparatus of  claim 8 , wherein said hammer defines a single weldment. 
     
     
         10 . The apparatus of  claim 8 , wherein said wherein said apparatus has a mass of at least one of 200 pounds, 350 pounds, 500 pounds, 750 pounds, 1,000 pounds, 1,500 pounds, 2,000 pounds, 3,000 pounds, and 5,000 pounds. 
     
     
         11 . The apparatus of  claim 8 , wherein said hammer includes a hammer head, and wherein said hammer is adapted such that said hammer head is readily replaceable with an alternate hammer head. 
     
     
         12 . The apparatus of  claim 8 , wherein said flexible elastomeric member defines a rubber isolator. 
     
     
         13 . The apparatus of  claim 8 , wherein said mount bracket includes a protective screen connected thereto. 
     
     
         14 . A excavator attachment apparatus for use in demolishing concrete and like objects by attaching said apparatus to an excavator arm and swinging said apparatus into said concrete or like object, said apparatus comprising a hammer device and a mount bracket, wherein said hammer device is connected to said mount bracket by pivotable hinge joint and by at least one flexible elastomeric member, and wherein said hammer defines a single weldment, and wherein said apparatus has a mass of at least 200 pounds. 
     
     
         15 . The apparatus of  claim 14 , wherein said mount bracket is connected to an arm of at least one of an excavator and a skid-steer loader. 
     
     
         16 . The apparatus of  claim 14 , wherein said wherein said apparatus has a mass of at least one of 350 pounds, 500 pounds, 750 pounds, 1,000 pounds, 1,500 pounds, 2,000 pounds, 3,000 pounds, and 5,000 pounds. 
     
     
         17 . The apparatus of  claim 14 , wherein said hammer includes a hammer head, and wherein said hammer is adapted such that said hammer head is readily replaceable with an alternate hammer head. 
     
     
         18 . The apparatus of  claim 14 , wherein said flexible elastomeric member defines a rubber isolator. 
     
     
         19 . The apparatus of  claim 14 , wherein said flexible elastomeric member defines a plurality of flexible elastomeric members, and wherein a first side of each of said flexible elastomeric members is connected to said hammer, and wherein a second side of each of said flexible elastomeric members is connected to said mount bracket. 
     
     
         20 . The apparatus of  claim 14 , wherein said mount bracket includes a protective screen connected thereto.
