Claims18
A system for lifting heavy items with a hydraulic bucket configured for scooping earth and loose bulk material, the system comprising:
- a bucket with a bucket bottom portion with a terminal bottom front end;
- a removable bucket ring attachment having:
- a front closed end and an opposing open end and further having an attachment width characteristic, an attachment length characteristic and an attachment thickness characteristic;
- wherein said removable bucket ring attachment comprises:
- an outside ring plate portion having a outer plate width characteristic, an outer plate length characteristic and an outer plate thickness characteristic;
- an inside plate portion having an inside plate width characteristic, an inside plate length characteristic and an inside plate thickness characteristic;
- wherein said outer plate width characteristic is substantially the same as said attachment width characteristic and said inside plate width characteristic;
- wherein said outer ring plate and said inner plate are substantially parallel and a plane defined by said outer plate width characteristic and said outer plate length characteristic faces an outside surface of said bucket bottom portion;
- wherein said outer ring plate comprises:
- an outer ring plate bucket facing surface and an opposing parallel outer ring plate attachment surface, where said outer ring plate bucket facing surface is free of any protuberances thereon;
- a means for connecting the outside ring plate portion to the inside plate portion at one end so as to leave an opposing end open and configured to receive therein said terminal bottom front end, where said opposing end is said opposing open end;
- an outer plate free end distal to said means for connecting, where said outer plate free end is free of any protuberances thereon;
- and
- an elongated flexible member receiving ring disposed on and rigidly coupled only to said outer ring plate at a location which is between said front closed end and said opposing open end.
