COVER STORY

safety features such as the LED load display that avoids overloading, as well as not being allowed to drive the truck without the safety belt engaged,” says Prigge. “It has been a favou- rite with the operators and has handled the tough site conditions well.” The 777E is designed to provide lower cost per ton through improvements in productiv- ity, fuel economy, durability and maintenance costs. It offers the highest payload and best safety features in its class, the same C32 ACERT technology engines as the F series, as well as other interchangeable components. The more efficient design of the E series makes it seven tons lighter than competing trucks. Servicing is more convenient with engine oil changes extended from 250 to 500 hours and hydraulic filter life extended to 1 000 hours. The Cat 777E also comes standard with technology to connect to Equipment Management Services for improved machine management and maintenance. This technol- ogy gives Barloworld Equipment customers the ability to listen to their machines and make decisions about maintenance, parts and operator training. The cab interior and operator station have been redesigned to provide better visibility and comfort. Safety is prioritised with a new industry-leading four-point access system that is stronger and wider. Other safety features include joystick gearshift control with inbuilt parking brake control, delayed engine shut- down to allow system components to cool down, which also extends component life, and engine crank lock out to lock the engine and disable the starter during servicing. 

deliver reliable, cost effective tons to our production plants in demanding mining condi- tions over their lifetime,” he adds. The 6030 BH is powered by two Cat C27 die- sel engines producing 1 530 hp (1 140 kW) and Cat C95 GET with hammerless design makes for simplified removal and installation of bucket teeth. Improving on its predecessor, the 6030, the Cat 6030 BH hydraulic mining shovel comes with an upgraded cab with advanced ergo- nomic design, superior visibility to the work area, and clear lines of sight to the stick and boom. Access walkways and hand rails were redesigned to enhance safety. The shovels will be paired with the fleet of six 100-ton capacity Cat 777 trucks on the mine for fast and efficient ore loading and hauling. Cat 777E truck Prigge says the mine is happy with the per- formance of its Cat 777 trucks, with corrosion and fatigue as the only issues affecting per- formance in the high hour machines. “These factors are managed by the Barloworld Equipment team as part of the overall mainte- nance plan for the fleet.” The first new Cat 777E truck landed in South Africa in March 2017 and has been eagerly received by the market as the succes- sor to the respected Cat 777D model, with several enhancements based on customer feed- back around the world. These, together with a competitive price, prompted Tronox to add a 777E to its fleet. “The new Cat 777E off-highway truck has operated for more than 3 000 hours on site, with reliable performance and value-adding

This view of the 6030 BH with employees from the mine and Barloworld Equipment gives some idea of the size of the machine, which has a payload of 33 tons.

“We expect these shovels to consistently deliver reliable, cost effective tons to our production plants in demanding mining conditions

over their lifetime.”
