previous largest hauler, the A40G which comes in at 24 m³. It is powered by a 16 ℓ D16 engine Volvo engine delivering 382 kW of power and 495 Nm of torque. While it is a high production machine, it’s not just the largest sites that can accommodate the new 55 t hauler. Although the A60H offers 40% more capacity than the A40G, it is only 432 mm wider, 940 mm longer and 254 mm higher than the A40G. According to Roger O’Callaghan, CEO of Babcock International Group’s African operations, thanks to the 33.25R29 tyres, the ground pressure of the A60H is better than that of the A40G and the A35G. Meanwhile, an added advantage is that the machine has many features familiar to A40G operators, eliminating the need for any major operator training. “It will be an easy transition for operators with only a short orientation course needed,” says Vaughan. Enter EC950E Mining operations place a premium on sizing excavators to maximise production with each truck load. According to Vaughan, the general rule of thumb is typically four to six passes or under 90-second loading. The goal is to maximise the total cycle time. The fewer passes that are made result in shorter cycle times, which in turn will increase production. With that in mind, the A60H has been launched in conjunction with the EC950E crawler excavator. With its 90 t capacity, it is designed to load the 55 t hauler cost effectively, achieving five to six passes per load. With over 424 kN of breakout force and 408 kN of tearout force, the EC950E offers a combination of power and stability to handle the high capacity duties in tough conditions such as hard rock mining, coal mining and big quarry applications. It is powered by a 446 kW Volvo D16 engine, the same motor driving the A60H, for parts commonality. The EC950E features a wide track gauge, long track length, a retractable undercarriage and an optimised counterweight, resulting in a well-balanced, solid machine. All machine

interfaces – including joysticks, keypad and LCD monitor – are ergonomically positioned and designed for optimum control and efficiency. Increased efficiencies Both machines can be purchased from Bab- cock with Customer Support Agreements, offering preventative maintenance, total repairs and several uptime services, while the latest intelligent systems from Volvo CE, such as MATRIS, CareTrack and the On Board Weighing System, allow fleet oper- ators to optimise production and minimise operational costs. CareTrack is the Volvo CE telematics system, which comes as standard on both machines, that offers access to a wide range of machine monitoring information designed to save the operator time and money. CareTrack generates a wide range of reports – including fuel consumption, operational hours and geographical location – via a web portal, as well as sending SMS/ email alerts. Fleet managers can use CareTrack to proactively manage their wear parts and their service maintenance. The benefits include a reduction in fuel costs, optimised machine and operator performance and increased uptime. Geo and time fencing features on CareTrack can notify the owner if a machine goes outside pre-set location and time boundaries. A status report provides access to fuel level, machine location and machine hours. With Volvo MATRIS analysis, Babcock can provide expert analysis of machine operating activity via this tool. MATRIS analysis supports optimised operation by tracking activity characteristics and identifying opportunities for improvement – resulting in better economy and reduced wear. The On Board Weighing System, standard on the A60H, guarantees optimal load every cycle. This maximises production, boosts fuel efficiency and reduces machine wear in all site conditions and operations. This load data can also be reviewed remotely via the CareTrack system. b

A60H,” says Vaughan, adding that Goodyear, Bridgestone and Michelin will manufacture these specialised tyres. Why A60H? According to Vaughan, interest in the A60H in southern Africa has been phenomenal. This was highlighted by visitors from as far as Zambia, Zimbabwe and Mozambique, going out of the way to attend the recent official launch in Middelburg. Six A60H units are already on order and currently en route to South Africa. Understandably, the machine, due to its sheer size, defines a new era in the global ADT space. With its 55 t capacity, the Volvo A60H is ideally suited for heavy hauling in high production sites such as opencast mines, quarries and large earthmoving operations. It is a machine that will help operations keep a lid on high production costs due to its higher payload that significantly increases productivity at lower cost per tonne production. With its 34 m³ capacity, the A60H delivers up to 40% more productivity than Volvo’s
