A rebuilt crane starts as you would think … removing all parts down to a bare frame. During this process every part coming off the machine is evaluated for reuse, repair, or replacement. A lot of parts are automatically placed in the “replacement” category like bearings, brass, nuts and bolts. There are many parts which can be repaired like a bearing block, the block is in good shape but the bushing is wore out, we simply push the old bushing out, clean and paint the bearing block and press in a new bushing.
