The M412 crawler mounted side discharge loader is a low profile

high output machine. The latest development in the fields of

hydraulics and fabrication and underground work are

considered while designing the loaders and they are developed

to offer maximum benefit to the mining industry. Flameproof

electricals make them suitable for operation in gassy mines.
