Epiroc has released the Scooptram ST4, which has been developed in close collaboration with customers, resulting in a compact underground loader tailored to the needs of small drift mines.<\/p>\n\n\n\n

This 4-tonne loader features a Stage V engine and has already undergone field testing, demonstrating impressive results in safety, productivity, and reliability.<\/p>\n\n\n\n

The new powertrain system, which includes updated components such as the transmission, converter, and engine options, significantly enhances the Scooptram ST4\u2019s overall performance. It is available with both Tier 3\/EU Stage IIIA and Tier 4\/EU Stage V engine configurations.<\/p>\n\n\n\n

Notably, both engine alternatives offer 20% more power than the Scooptram ST2G\u2019s current engine. In addition to faster cycle times and improved efficiency, the Stage V engine meets the highest emission standards, significantly reducing particulate matter (PM) and nitrogen oxides (NOx) in mining operations, thus improving underground air quality. These environmental benefits are further amplified by the loader\u2019s compatibility with HVO100 fuel, which helps reduce the overall CO\u2082 footprint.<\/p>\n\n\n\n

\u201cThe Scooptram ST4 builds on years of experience from its predecessor, the Scooptram ST2G, and features major upgrades, particularly in productivity. With a completely new powertrain system and redesigned rear frame, combined with our proven safety features, this compact yet powerful loader is already making a positive impact in our customers\u2019 operations, as seen in earlier field trials,\u201d said Mary Zhu, global product manager, Scooptram \u2013 Small Segment. <\/p>\n\n\n\n

\u201cThe new powertrain is the foundation of the Scooptram ST4\u2019s superior mucking capabilities. Field trials show a 26% increase in average traction force compared to the ST2G, along with a 19% improvement in mechanical breakout force,\u201d added Zhu.<\/p>\n\n\n\n

Additionally, the loader demonstrates a 27% increase in revolutions per minute (RPM) during mucking and hydraulic operations, and a 13% reduction in total cycle motion time. This results in faster bucket movements and hydraulic responses, leading to better fill factors and quicker loading. The enhanced powertrain enables the Scooptram ST4 to achieve up to 45% faster tramming speeds on flat ground with a loaded bucket and maintain higher gears even when tramming uphill under full load, delivering a notable boost in tonnage output per cycle. <\/p>\n\n\n\n

Another key upgrade is the redesigned rear frame, which improves both safety and reliability. The new layout lowers the frame by 100 mm, significantly enhancing operator visibility. High-quality components, such as a reinforced drive shaft and the optional passive Diesel Particulate Filter (pDPF) system, further increase reliability by enabling longer service intervals, reducing maintenance needs, and ensuring consistent performance in demanding underground conditions. <\/p>\n\n\n\n

The Scooptram ST4 is designed for drift sizes with a minimum height of 2.8 meters and performs exceptionally well at high altitudes. Field trials conducted at a mine located 4,100 meters above sea level showed the loader delivering up to 12% more power compared to the previous model.<\/p>\n\n\n\n

The Scooptram ST4 is now available for the global market, with the first customer order currently in production.<\/p>\n\n\n\n
