Swann Blaise presents a case study on a mining excavator in operation in South Africa GREAT excavations
The R 9200 at the Beeshoek mine
province of South Africa. Composed of fi ve open-cast pits, Beeshoek’s production output is around 3.4 million tonnes a year. T e mine is jointly managed by ARM Ferrous (a subsidiary of African Rainbow Minerals) and Assore, through Assmang. Beeshoek undertakes its own mining but also contracts out a smaller proportion of its mining requirement through a Plant & Hire contract, attributed to South-Africa based company, Basil Read. T is company is active in opencast mining, civil engineering projects, road construction, building, mixed integrated housing developments, property development and related services, and is among Liebherr’s

major customers. As of 2015, Basil Read holds a fl eet of 20 Liebherr mining excavators, including fi ve units operated at Beeshoek mine. To sustain Assmang’s ambitious stripping target and initially as part of a pre-series agreement with Liebherr, Basil Read was the very fi rst operator of the new R 9200, since February 2015. As the machine demonstrated high performances and successfully passed the fi eld test period, Beeshoek decided to purchase it. During the fi eld tests, the observed availability on the R 9200 working at Beeshoek exceeded 90%. T e machine has been developed to promote easy and fast maintenance: its service fl ap is accessible from the ground level and off ers direct access to fuel, engine oil, grease and hydraulic oil refi lling points. Fitted with Wiggins quick couplings for all fl uids as a standard feature, the required time to refi ll
