About UsThe Robbins Company is engaged in the design, manufacture, sale and rental of custom equipment for the underground excavation industry. Robbins products excavate materials, including very hard rock, mechanically as opposed to the traditional "drill and blast" method.
Mechanical rock excavation today provides a much more cost efficient method of tunneling than drill and blast. The drill and blast method is necessarily a sequential operation: drill small diameter holes, load with explosives, blast, ventilate, remove muck and start the cycle again. Mechanical rock excavation is a continuous process whereby rock is "cut" from the tunnel face and removed by conveyor or train from the tunnel. Robbins' primary product is tunnel boring machines (TBMs).
TBMs are used to excavate circular cross-section tunnels through a wide variety of geology, from soils to hard rock. Robbins has produced TBMs which have excavated tunnels from 1.6 to 12.87 meters. Machine weights range from 50 to more than 1500 metric tons, total installed power from 300 kW to more than 3000 kW.
Robbins also designs and sells a wide range of other equipment and services which are required for efficient utilization of a TBM.
