High Technology Diesel or Electric Underground LHD

diesel or electric underground L.H.D

DRWJ-1 is a1metric tonne underground loader for small-sized operations ranging from construction sites to narrow-vein mining at extreme altitudes

Improvedfuel economy&Less fuel with better combustionfromDeutz&CUMMINS

Great power fromrear mountedengine

Perfect balance between low effort controls and powerful forces for smooth and fast cycle time

Conventional and proven components are well protected within the frame, resulting in low maintenance costs

Compact and powerful design

Improvedfuel economy,Less fuel withbetter combustion

Great power from Deutz rear mountedengine

Robust and efficientDANA Power Train-Transmission

Heavy duty axles with 100% LSD

key parts from MICO guarantee the high performance of the braking system
