Atlas Copco launches an improved 10t underground loader - the Scooptram® ST1030

An improved electrical system, an EPA Tier 3 diesel engine and a new instrument panel represent the major improvements being incorporated in Atlas Copco’s new front end loader; the Scooptram® ST1030. This new model, replacing the ST1020, is the latest member of the ST10X0 progression. A large number of design changes have been made to keep this 10 metric tonnes capacity loader at top production levels in medium to large sized underground operations.

The most important improvement, from a service point of view, is the electrical system. It has been redesigned, with focus on reliability and serviceability. Erik Svedlund, service engineer at Atlas Copco, says:
“-The reduction of downtime due to electric failures in the electrical system has resulted in a further increase of machine productivity”.
Another service friendly change is the new display panel, which replaces the previous gauge cluster arrangement. The new instrument panel features an integrated warning system and an engine fault code display. The system also indicates when it is time to change the air filters.

Change of engine

Among all the improvements, the change of engine is the most noticeable. The QSL9 Cummins engine uses the high-pressure common rail system to meet the EPA Tier 3 requirements. It has an optimized design resulting in a favourable relationship between size and costs which gives high productivity. The engine has a high energy density design providing a compact installation which facilitates service. The engine also provides electronic protection for overheat or low oil pressure. Trial tests conducted in Chile and Brazil with ST1020 equipped with the QSL9 engine has been successfully completed. 

Two vehicles have been in operation for more than 2 200 hours each. Comments from the Jacobina Mine in Brazil include more power, lower fuel consumption, less noise and emissions and a higher availability. Cummins is a major engine supplier with a worldwide sales and service network. As part of an agreement between Cummins and Atlas Copco, Cummins will provide “Limited Repairer” level training to Atlas Copco service personnel at Customer Centres located throughout the world. 

Other changes

Other changes worth mentioning are the Ansul system as standard and improved routing systems for hydraulic hoses and electrical wiring. Additionally, the transmission hydraulic cooler has been changed to improve the cooling capacity. Finally, the new vehicle is fitted with a service bay in the rear fender for fuel and oil filters.
