MgM Rotar
Objective
Provide a capability to sift mines from soil.
Description
The MgM Rotar is an armored vehicle system for safely excavating
and sifting mine contaminated soils. The system is constructed from a
commercially available rubble sifter, modified and mounted on a mine protected
front end loader. The system picks up a bucket load of soil and closes
a cage around the contents. The soil is then tumbled by rotating the cage,
separating all contaminants smaller than the grid size. The loader is
moved out of the hazardous area and the cage opened. The sifted contents
are spread on the ground in a predesignated area or blast-protected container
for visual inspection by deminers. The system can withstand explosions
from both blast and fragmentation AP mines with minimal damage.

Performance
In tests against surrogate mines
in Namibia, the MgM Rotar demonstrated a 99% clearance capability
in one test that was certified by Price-Waterhouse. In another test, the
system also cleared 14 live AP mines from two mined berms next to powerline
pylons. These berms had previously been declared mine free by commercial
contractors. The Namibian Defence Forces certified the MgM clearance (combined
process including the Rotar) of the pylon berms at the 99.6% United
Nations clearance standard.

Limitations
- The system is limited to use in areas where the
front loader can operate.
- Highly cohesive and vegetated soils may not sift
effectively.
- Large blast mines, in particular AT, may damage
the Rotar.
Status
The prototype system has undergone extensive testing
in Namibia and additional systems could be produced in a relatively short
period of time.
