Abstract

Abstract A machine for handling bales comprises a chassis frame (1,2,3) which can be raised or lowered by movement of wheels (16,17) relative to the frame. Bale engaging means which can be constituted by movable frame members (2,3) and/or gripping elements (9,10) attached thereto, are movable to engage and disengage a bale or group of bales. With the frame lowered, a bale or group of bales is engaged and then the frame is raised by the wheels to lift the bale(s) from the ground for transport. In a preferred embodiment, the distance by which the bales are raised permits them to be located over a second bale or group of bales. The first bale(s) can then be released from the bale engaging means to rest upon the second bale(s) and the frame lowered to permit the second bale(s) to be gripped and raised from the ground thereby permitting a stack of bales to be built up.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 221 words
A bale handling machine comprising: a generally U-shaped chassis frame having a pair of laterally spaced arms extending rearwardly from a forward cross-member to define a bale-receiving zone which is open from below and has an open rear end to receive a group of bales and closed forward end; a tow bar extending forwardly from said cross-member and adapted for connection to a towing vehicle; a pair of laterally spaced wheels supporting said frame above the ground for translational movement of the frame and movable relative to the frame to lower and raise the frame between a lowered bale-receiving position and a raised bale-transport position; a pair of mutually horizontally opposed gripping elements mounted on respective arms of the frame, said gripping elements being relatively movable to grip and subsequently release bales located between them; the said wheels being at the forward end of the frame and spaced rearwardly of the cross-member by a distance less than the length of the tow bar, and the vertical distance moved by the wheels relative to the frame being at least 14 inches and greater than the individual height of the bales which the machine is intended to handle, whereby the machine can place a transported bale onto a bale standing on the ground and subsequently raise and transport the resultant stack of bales.
Claim 2
Dependent Claim 221 words
A bale handling machine comprising: a generally U-shaped chassis frame having a pair of laterally spaced arms extending rearwardly from a forward cross-member to define a bale-receiving zone which is open from below and has an open rear end to receive a group of bales and closed forward end; a tow bar extending forwardly from said cross-member and adapted for connection to a towing vehicle; a pair of laterally spaced wheels supporting said frame above the ground for translational movement of the frame and movable relative to the frame to lower and raise the frame between a lowered bale-receiving position and a raised bale-transport position; a pair of mutually horizontally opposed gripping elements mounted on respective arms of the frame, said gripping elements being relatively movable to grip and subsequently release bales located between them; the said wheels being at the forward end of the frame and spaced rearwardly of the cross-member by a distance less than the length of the tow bar, and the vertical distance moved by the wheels relative to the frame being at least 14 inches and greater than the individual height of the bales which the machine is intended to handle, whereby the machine can place a transported bale onto a bale standing on the ground and subsequently raise and transport the resultant stack of bales.
