Rock cutters added to American Augers line-up
American Augers and Trencor have come together under parent company The Charles Machine Works, to develop a four-model line of surface mining machines. Using an American Augers mining head, with a Trencor trencher chassis, the machines offer a cost-effective means of removing material without drilling and blasting. The machines offer cutting widths of 3.2-4.5m with maximum cutting depths of 0.91-1.1m.
The T1360 is the smallest machine in the line, powered by a 328kW Caterpillar C13 engine. This is followed by the T1460, with a 470kW CAT C18 engine, while the T1660 and T1760 use a CAT C27 motor, offering 597kW and 708kW respectively. All four models have infinitely variable hydrostatic transmissions to provide smooth travel with independent cutter drive speeds.
American Augers is also introducing a range of roller cone cutting heads to its auger boring tool line. The roller cone cutters offer similar performance but at around half the price of previous cutting heads. Sizes range from 600-1,200mm in regular heads, though the company says that it can produce roller cone heads right up to 3m diameter.
