A hydraulic concrete breaker and post driving tool 1, 2, with attached hydraulic grapple 3 mounted in either a fixed position on the post driver body, or on a rotation device attached to the post driver body (8 on fig 4). The device may include a guide for alignment such as a weighted chain 7 attached via a mount 6. The entire device is able to be mounted to a carrier vehicle such as an excavator, tractor, or crane, for example. The device allows posts to be picked up by the grapple, individually or in a bundle, and positioned vertically, allowing the pile driver tool to then engage with the post and drive it into the ground without the need for additional support. |
