<p>The excavator machinery comprises a series of toothed wheels arranged on a drum and revolving upon a common axis. Excavated material is discharged onto a transfer platform and from thence to an inclined continuous conveyor belt which deposits it at the rear of the excavator and into a raised position, suitable for charging onto a transport vehicle. The excavation equipment may be moved forwards and backwards by a endless track type tractor with two equal diameter driving wheels at either end. The machine incorporates two chassis which may be rotated relative to one another.</p> |
