REBUILDS
Six 218 t Cat 793D trucks from Brazilian iron ore mining company CSN have gained a new life after undergoing a complete overhaul via a Cat Certified Rebuild by dealer Sotreq
Manager of Maintenance and Engineering at CSN . The Caterpillar Certified Rebuild ( CCR ) was carried out at Sotreq ’ s Vespasiano unit , which has been completely reformulated and has five workshops .
It is a complete structure for renovations , recovery , tests and adjustments to serve customers in mining and other segments , following Sotreq & Caterpillar quality standards . In addition to the technical aspect of the equipment rebuild , the financial aspect is also taken into account by the company when opting for the rebuild . “ In fact , the big point is the costbenefit ratio , that is , this renovation allows us to have equipment with new features and performance but with a much lower investment . In addition , the big point that makes the project feasible is the extension of the asset ’ s useful life .”
Rodrigo Amaral , Product Support Manager at Sotreq , confirms this cost-benefit advantage : “ A CCR for large mining equipment , on average ,
Liebherr - reman in Indonesia during the pandemic
PT Liebherr Indonesia Perkasa was established on the Indonesian island
of Borneo in Balikpapan , East Kalimantan in February 1997 . Since then , Liebherr Indonesia has provided local representation for the Liebherr Group and its mining product portfolio . Liebherr Indonesia focuses on the distribution and service of hydraulic excavators , dozers , and off-highway trucks , and provides a range of other services such as component remanufacturing and key component production .
Liebherr Indonesia established its remanufacturing business in its early days in 1997 . The strategy behind local remanufacturing was to improve and extend the proposed services for customers after an equipment sale . Liebherr Indonesia ’ s remanufacturing program enables splitter box rebuilds and cylinder resealing services . These tasks are supported by the locally trained and experienced technicians under the supervision of General Manager of Operations Graeme Dalzell , Maintenance Advisor Carter Byron , and Remanufacturing Supervisor Rudi Hartono .
Although Indonesia was hit hard by the global COVID-19 pandemic , the latest commodity price surge has driven the demand for locally remanufactured components to assist with the re-commissioning of previously parked equipment , enabling an increase in mine ’ s production targets .
However , the pandemic introduced its own new set of challenges for the company . International parts supply chain interruption has had a detrimental effect on Liebherr Indonesia ’ s remanufacturing capabilities , as the availability of required parts is not consistency with pre-pandemic levels . Furthermore , the work force reduction due to local government regulations , limiting the total numbers of staff permitted in the facilities to 25 %, has also had its impact . To face the new situation , a shift in mindset was necessary , as Dalzell explains . “ It is our priority to plan the component changes , and review parts requirements and stock levels ”, said Dalzell . “ We assign labour to components for which all required parts are available , or their delivery is imminent .”
Another strategy that has been implemented by Liebherr Indonesia during the pandemic is to increase preventive component exchange , by aligning with the component ’ s given service life . Oil analysis reports , and monitoring for abnormal wear in the system that has an adverse effect on component life , is also important . This strategy decreases the risk of failures that may require the replacement of additional components not normally necessary to be changed . This benefits both the customer and Liebherr ’ s parts planning process .
Fortunately , with the availability of professional local technicians , the post-pandemic work performance has been maintained to the pre-

pandemic levels . All health , safety , and environment measures continue to be implemented to ensure Liebherr Indonesia technicians ’ wellbeing .
The Liebherr Group holds strong family values which are also shared by Liebherr Indonesia . Liebherr Indonesia works and interacts as a family , taking care of each other no matter how difficult circumstances . Liebherr Indonesia ’ s Remanufacturing Supervisor , Rudi Hartono , shared his story about his many years with the company . “ I have experienced so many things , but this pandemic will be one of the most memorable stories . It is very challenging to work with limited manpower and working-hours while trying to deliver the best support for the customers and maintain our wellbeing at the same time .” Hartono further added , “ I am glad to have a reliable team and thanks to everyone involved , we are able to maintain a great result and fulfil the customers ’ needs .”
Liebherr Indonesia ’ s Managing Director Christian Bombenger added , “ Remanufacturing is a key activity and a necessity to support our business and our customers by providing the highest quality products and services . To achieve the highest quality , Liebherr Indonesia strictly adheres to the Liebherr Mining Remanufacturing guidelines and processes , as well as the ongoing and tailored training programs for the workshop technicians ."
Liebherr Indonesia says it " consistently strives to provide a pleasant and safe working environment for all employees , especially during the pandemic , in order to maintain good performance standards and achieve outstanding deliverables for customers . While the situation is certainly challenging , nothing is impossible for Liebherr Indonesia and its dedicated workforce ."
