发明名称 Claw attachment for backhoes and excavators
摘要 A claw attachment for use in conjunction with the bucket of a backhoe or excavator for removing large boulders and other objects from the surface of the ground or from a partially embedded position within the ground. The claw is removably mounted in a fixed bracket on the earth moving machine and can be secured in a first or operative position on the "crowd" and then relocated to a second or storage position on said "crowd". In configuration, the claw resembles the claw of a Maine lobster, but with a pair of normally disposed outward extending ears toward the front thereof.
