Hyundai Heavy Industries (HHI) has recently added the HX520 L to its excavator line-up to meet growing demand in the market for strong, reliable and economical excavators. This Tier 4F/ EU Stage IV compliant excavator is among the six all-new HX excavators ranging from the 22-ton HX220 L to the 52-ton HX520 L that HHI debuted at Intermat 2015.
HX models standing for ‘Hyundai Excavators’ boast the greatest extent of improvements on the existing Hyundai line-up. All HX series excavators are Tier 4F/ EU Stage IV compliant and more operator friendly and robust than their predecessors.
Equipped with a new, fuel-efficient and eco-friendly Scania engine, the HX520 L can perform 3% faster truck loading and up to 6% faster leveling. It can achieve this improved productivity with greater fuel efficiency: it is up to 7% more fuel-efficient in leveling and generates 90% less PM and NOx.
To back up such improved performance, the HX520 L offers a variety of intelligent electronic support for operators: Eco Gauge enables economic and efficient operation of the machine that shows engine torque and average, daily and hourly fuel consumption rate; Intelligent Power Control (IPC) controls the fuel pump flow depending on work environments; and three-mode power control (power, standard, economy) ensures fuel efficiency.
The strength of the HX520 L is also evident in its durability. Proven by rigorous tests, the robust upper and lower frame structure can endure sustained external shock and high-load work, thereby making it ideal for use in tough working environments such as mining, quarrying and demolition operations. The machine also gets a boost from its expanded cooling module.
Moreover, the equipment has improved lubricity of the connecting parts between the equipment and the attachments along with wear-resistant long-life pins, bushes and polymer. A wear-resistant cover plate placed at the end of the arm minimizes abrasion on the connector between the arm and the bucket. Durability of the arm and boom has also been reinforced, compared with the previous generation 9-series.
HX520 L offers a range of features that boost operator comfort and convenience: an enhanced instrument panel comprised of an extra-wide intelligent cluster with excellent legibility; an integrated haptic-type controller facilitating convenient operation; a wi-fi link up with smart phone system; a radio player, USB-based MP3 player and an integrated Bluetooth hands-free feature allowing convenient phone calls at work or in transit.
A low-vibration design with coil spring and damper inside the mount has been incorporated to reduce noise inside the cabin and improve durability, reducing operator fatigue.
In terms of safety, it is equipped with the Advanced Around View Monitoring (AAVM) system that secures the field of vision for all directions and enables the operator to detect people or dangerous objects within a 5m range.
By using Hi-Mate, Hyundai’s proprietary remote management system, the operator and dealer service personnel can access vital service and diagnostic information on the machine from any computer with internet access. This allows preventative maintenance and reduces downtime, thereby saving money and time for the owner and dealer.
Koo Ja-jin, an executive vice president R&D at HHI, construction equipment division, said, “HX series excavators including the HX520 L are a materialization of HHI’s long-standing efforts to meet the needs of our clients for both powerful and fuel-efficient construction equipment. We will continue to strives to bring greater satisfaction to our customers through ongoing product improvement. We will tide over the increasing competition on the strength of better products and services.”
HHI plans to introduce the equipment in the North American markets in the second half of 2015.
