Grydale hold the patent for manufacturing the only self propelled Dust Collector on the market.
The JMS-40-MDT (Diesel, Track) and JMS-40-MHT (Hybrid, Track) units are able to move and operate alongside excavation equipment, such as road headers, surface miners, profilers, and trenchers. Track units offer full mobility with variable speeds between 2-4 k.p.h. to increase the speed and efficiency of operations.
The JMS-40-MHS (Hybrid, Stepping System) features four hydraulic legs lift the unit up while a pair of skates help to move the unit forward/backwards. Movement can be repeated to achieve the desired travel distance.
The JMS-40-MDS (Diesel, Skid) and JMS-40-MES (Electric Skid) units can be easily moved with a crane using the four lifting lugs or dragged into position using the rigging mounts at the end of the machine. Units mounted on drag skids are perfect when dust collection needs are relatively static.
