Chain Drive Post Driver The Cross post driver is the only chain drive and free fall post driver on the market. This unique system allows for the most substantial contact force of any other post driver available.
The chain system lifts the 400kg wieght to the top of the mast where the weight is released and free falls. This means no large rush of return oil to the tractor like a ram and rope machine. Smaller hits can also be achieved by only lifting the weight to a chosen height and reversing the hydraulic motor. |
