Abstract
Abstract A counterweight structure for use in counterbalancing earthmoving apparatus, such as a loader, having a removable backhoe. The counterweight includes bracket structures for facilitated mounting of the counterweight to different supports carried by the drive machine of the earthmoving apparatus. One of the bracket structures is adapted for temporarily supporting the counterweight on a support portion of a removable section of the earthmoving apparatus, such as the backhoe thereof. The bracket structures are adapted to permit the transfer between the different supports by normal operation of the apparatus whereby a transfer may be effected by a single operator.
