The DRWJ-1 hard rock loader is a diesel-powered heavy-duty machine intended for the most demanding mine environments. The DRWJ-1 is only 1.38 meters wide (1.38 is width of bucket, width of frame is 1.24-1.28 meter) so it is perfect for small narrow-vein applications where maneuvering space is limited.
The DRWJ-1, like all DERUI loaders, is designed specifically for ease of use and maintenance, with simple operation gauges and a rugged long-life structure, providing the lowest possible total costs of operation including low capital costs.
In addition to mining applications, the compact and agile equipment fits well for civil engineering and construction projects for building new and improving existing infrastructure. Due to its relatively light weight and the possibility to disassemble the equipment for transport, the DRWJ-1 is a fit match for small-dimensioned construction sites, even if located in remote areas within challenging access.
