Maintenance Research Corner
The test-bed tandem
The members of the Mn/DOT New Technology, Research, and Equipment Committee (NTREC), as well as staff of Mn/DOT's Maintenance Operations Research (MOR), publish a monthly one-page bulletin of their latest news and findings. Below are highlights from recent bulletins. If you would like to be added to the bulletin mailing list, please e-mail Benjamin Zwart of Mn/DOT Maintenance Research at ben.zwart@dot.state.mn.us.
Test-bed tandem project
This project is ongoing and almost constantly in a state of change. It will be back in the field at the Golden Valley Truck Station for evaluation of several new components. A completely new hydraulic valve body has been engineered and installed that includes wireless connections with the material controller. Evaluation of a prototype LED (light-emitting diode) emergency lighting system will be included, as well as a newly designed front plow featuring a 45-degree attack angle.

Hydraulic oil recycler and oil pre-cleaning
Dirt and other friction-causing contaminants greatly reduce life expectancy of hydraulic pumps and both diesel and internal combustion engines. This oil recycler system is claimed to clean hydraulic oils and new motor oils better than manufacturers' recommendations. This being the case, it could greatly improve longevity of engines and other mechanical equipment and reduce maintenance and repair costs.

Pack-a-cone
Due to the amount of equipment, tools, and other supplies that are required in field mechanic trucks, space is at a premium. To allow for additional room in mechanic trucks, "pack-a-cones" are being evaluated in temporary work zones needed for equipment breakdowns and other short-term instances. The Mn/DOT Safety and Traffic Offices approved this project in District 7E.
