Compact radio remote control track driven machines for construction and mining applications.

The idea that started Rohmac Inc.  A compact machine that could go into difficult to access areas of underground mines, with the capacity to perform work that had required demanding physical labor. A versatile machine that could quickly change implements to perform tasks ranging from loading and lifting debris, to hauling payloads; the track drive allowed it to traverse the most difficult of terrains, and the compact size allowed it to work in areas where larger equipment could not go. MICROTRAXX™ equipment is truly Power for Confined Spaces. The addition of radio remote control to the machines allowed work to be performed in hazardous areas, keeping the operator safely away from harm. 


MICROTRAXX™ construction equipment is often used in culvert and bridge applications. Models SL 436, MT 3234, and MT 2242 remove material obstructions quickly and efficiently from drainage structures as low as 24” in height. These machines are designed tough while being capable of working in environmentally sensitive areas such as stream beds. The use of biodegradable fluids in these machines help to reduce their environmental impact.

MICROTRAXX™ equipment for underground mining ranges from compact track loaders, tool carriers, and purpose-built payload hauling machines, drilling machines, and cutting machines, to the BC 1530 belt entry cleaner, made to remove material accumulated under the conveyor and discharge it onto the conveyor belt. A variety of power options are available, from electric to diesel. Let us tailor a MICORTRAXX to suit your needs.

MB 530.jpg

MB 530

Underground mines are dynamic environments, with changing roof and rib conditions. The MICROTRAXX MB 530 was built to help respond to these conditions when additional roof or rib support is needed. The compact machine can work around belt lines or other equipment, and is powered by hydraulic or even emulsion PTO lines, to put bolts where they are needed.

♦ Narrow footprint allows it to bolt along side of a belt line
