The Excavator of Tomorrow – Power by Scania

Scania Press Release / August 20, 2015

Doosan’s new 50 metric ton DX530LC-5 excavator is undergoing endurance trials in the mountains of South Korea’s South Chungcheong province, and Scania is playing a key role.

When you’re in the quarrying business, you need heavy machinery that you can depend on. With environmental regulations around the world rapidly becoming tougher, you also need equipment that meets the latest emissions standards.

The process of developing just such equipment is now underway in South Korea, where industrial and construction equipment maker Doosan is working with Scania and local customer Bochang Industries.

In the mountains surrounding the South Korean coastal city of Boryeong-si, the three companies are testing the DX530LC-5, a powerful large excavator featuring a 13-liter Scania DC13 Tier 4 engine. The excavator aims to marry functional engine design and low emissions output to produce a piece of heavy machinery capable of turning rocks into gravel.

Featuring XPI (extra-high pressure injection - 2400 bar) common rail fuel injection and Selective Catalytic Reduction (SCR), Scania's 13-liter DC13 engine is able to meet Stage IV emissions without the use of a Diesel Particulate Filter (DPF), so there's no reduction in operational productivity due to regeneration requirements.

Testing ground for Scania Doosan cooperation

Bochang Industries excavates rock that is then crushed into gravel for construction use. It has excavated a long string of hillsides around Boryeong since 1992.

Bochang’s quarry has been a testing ground for Doosan products since 2004. With Doosan and Scania signing an agreement in 2014 to produce Tier 4 final engines for Doosan’s new series of 40 to 50 metric ton excavators, the focus of activities in the quarry has been on the heavyweight DX530LC-5.

The testing process involves a prototype being put to work, and Scania and Doosan working together with Bochang to rectify any unforeseen problems. So far, the prototype has clocked up 500 hours of operating time.

Scania’s Engineering Project Director in Korea, Ian Hooper, says, the new excavator incorporates significantly higher levels of technology to control emission levels.

Quiet and responsive

Lee Young Woo, an excavator driver with 25 years’ experience, has been testing the DX530LC-5 and says it is quiet and responsive. “The dynamic characteristics are better than other machines,” he says. “The noise level is lower and the engine response is better. With more engine space, it’s easy to maintain and the ergonomics of the pedals are more functional.

With increased power, Woo easily shifts around 250,000 metric tons daily, with the 380 horsepower Scania engine returning to its 1,800 rpm in less than a second under load.

“This machine lets me utilize all its engine power,” says Woo.

Long relationship with Scania

Having a Scania engine in the quarry is no new experience for Bochang Industries. The company uses a wide array of Scania-powered equipment in its day-to-day operation.

Its relationship with Scania began in 1995 when Bochang’s manager, Juhun Kwon, began operating Scania vocational trucks. He says the experience highlighted the performance and reliability of Scania engines.

“Excellent fuel consumption, durability, and reliability of the engine are the key factors in our choosing Scania engines,” Kwon says. “Importantly, we have access to many service dealers, including Doosan and Scania, so it’s easy to get parts.”
