Volvo’s new EC950E excavator is the largest excavator the company has ever built, and was designed to load the A60H with maximum efficiency. offers the perfect combination of power and stability to handle high-capacity duties in the toughest applications, particularly when working with hard and heavy materials. Like the A60H, the fuel-efficient EC950E heavy- duty excavator features the powerful Volvo 446kW D16 engine and comes standard with Volvo’s CareTrack telematics system. It also features a new electro-hydraulic control system with intelligent technology that allows the system to control on- demand flow and reduce internal losses in the hydraulic circuit. Combined with Volvo’s unique ECO Mode, this reduces loss of flow and pressure to improve fuel efficiency. The integrated work mode also allows operators to choose the best work mode for the task at hand. The EC950E’s wide track gauge, long track length, retractable undercarriage and optimised counterweight result 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, and operators can work comfortably and confidently in the most challenging environments in the comfortable, low-noise cab. Essential maintenance points are easily accessed via the wide-opening and conveniently located compartment doors using central and surrounding walkways. For 24 _ QUARRY SA | JULY 2017 added safety and durability, a full-length track guard can be fitted and optional Falling Object Guard (FOG) and Falling Object Protective Structure (FOPS) certified cabs provide peace- of-mind. One Indonesian mining contractor that has already experienced the exceptional productivity of the EC950E is Samudera Mulia Abadi (SMA), which brought two of crawler excavators in to its operations at a Manado gold mine earlier this year. Since introducing the EC950Es, SMA, which has over 60 Volvo machines working on the site – including six 75-tonne rated EC750D excavators – has seen its fleet productivity increase by up to 30%. Improved production, lower CPT According to Vaughan, the decision to build a 60-tonne ADT came down to volumes and cost-per-tonne (CPT). “The initial tests done by Volvo overseas show that the A60H is highly cost-effective. While there are several rigid 60-tonne trucks on the market, they require haul roads to be in very good condition. Given the (often) difficult on-site conditions in Africa, including high rainfall, the option to use an ADT over a rigid vehicle without sacrificing payload capacity is one we believe will have a high take-up. We expect the A60H to compete very well against the rigid 60-tonne market.” EC950E crawler excavator: key specifications EC950E T2/T3 Specification and unit Engine Volvo D16E Rated output at 1 800rpm ISO 9249/SAE J1349 net 446kW Breakout force (Normal/Boost) SAE J1179 424kN/- Bucket capacity 3.9–5.6m 3 Max. digging reach 12.270m Max. digging depth 7.120m Lifting capacity along undercarriage 37 460kg At reach/height 6.0/1.5m Operating weight 89 96 to 91 840kg * Based on machine configuration: 7.25m boom, 2.95m arm and 16 100kg CWT.
