technicians to fully understand the machine, its capabilities and its complexities,” he says. “With any new generation machine, there is always an element of training.” He emphasises that the Pilot Crushtec team is also well equipped to assist customers with upskilling their operators and maintenance teams so they can extract full value from the technology. Marais highlights how the improvements in design impact both operation and maintenance, reflecting Metso’s broader design philosophy of integrating real-world operational feedback into equipment development. He points to the redesigned extended discharge conveyor as an example. “The discharge conveyor can operate at three different angles,” he explains. “You can raise it to build a higher stockpile, lower it to feed directly into the next unit in the crushing circuit or drop it horizontally to the ground for maintenance access.” This last function is particularly significant as it allows technicians easier access to the underside of the jaw crusher – an area that often becomes difficult to inspect or service on conventional machines. “Liner changes have also been simplified,” he notes. “The LT400J incorporates dedicated lifting tools and improved access around the fixed jaw end, making the removal and replacement of wear liners safer and more efficient.” In addition, the bypass chute behind the jaw crusher is hydraulically adjustable, allowing it to move away from the service area and improve working space during maintenance. Warren adds that the machine was effectively redesigned from the ground up. “Every aspect was reviewed and improved where it could be,” he says. “There is now enhanced engine access through large gull-wing doors, for instance, providing clear unobstructed access to service components.” Combined with reduced hydraulic complexity – including a much smaller hydraulic tank used primarily for tracking and setup – these design improvements help shorten service times, reduce maintenance effort and ultimately increase machine availability in demanding African applications. Enhancing the value of mobility in crushing, the Metso LT400J’s track-mounted design allows rapid relocation within a site or between sites, enabling operators to respond quickly to changing production requirements. n
The control panel of the Metso Lokotrack LT400J integrates advanced IC process automation, enabling operators to monitor key parameters and adjust crusher settings for consistent, efficient production.
The digital controls support improved production consistency and preventative maintenance by providing clearer operational data and system status information. Customers can respond more rapidly and conduct quicker troubleshooting, reducing unnecessary stoppages and limiting downtime. The significant technological advances in the LT400J – in terms of software, sensors and control philosophy – call for a high level of technical understanding for both operation and maintenance. Typical customers are therefore expected to be sophisticated operators with the necessary skills and resources. “Our strategic relationship with Metso ensures that Pilot Crushtec continuously develops its aftersales support, training and technical readiness for new technologies,” Warren says. “We invest in ensuring that both our teams and our customers are equipped to manage the advanced digital and electrical systems on the crushing solutions we provide.” For the arrival of the Metso LT400J in South Africa, two senior Metso master technicians, including one from the factory where it was built, were hosted at Pilot Crushtec’s Jet Park facility to conduct in-depth training sessions with the local technical and workshop teams. “Working directly with the factory specialists allows our
