Volvo excavators at work in the Alam Jaya volcanic rock quarry
A Volvo EC220DL excavator is said to be increasing productivity by 30% at the Alam Jaya volcanic rock quarry in Indonesia, and also reducing fuel consumption by 2litres/hour.
At the foot of Tangkuban Perahu, a dormant volcano that last erupted in 1983, is West Java’s capital city, Bandung, home to 2.5 million people.
At 768m above sea level, Bandung enjoys one of Indonesia’s coolest climates, with an average year-round temperature of 23°C. It does not escape the tropical rainstorms however, and sees average rainfall of an incredible 3,500mm a year in some parts.
Located just outside the city is aggregates producer Alam Jaya. The company excavates Andesite volcanic rock and crushes it into various sizes of aggregate for use in general construction and roadbuilding throughout West Java.
It uses three Volvo Construction Equipment (Volvo CE) excavators, including two EC210B-Primes and one EC220DL to load the rock onto trucks amid what looks like a lunar landscape.
The company’s owner, Hj. Nendah, purchased his first Volvo machine in 2012 and was pleased with the EC210B-Prime model.
“I was very satisfied with the machine’s performance. It had always been reliable, even when the weather conditions made operations more difficult,” he explains.
ITU is Volvo’s dealer for the island of Java. The company has a local sales, spare parts and service branch in the province for fast, responsive aftermarket support. Its team of technicians has been trained by Volvo to resolve issues in the shortest time and to offer maintenance advice to customers.

The EC210B-Prime features a Volvo D6E engine with a power output of 106kW at 1,800rpm. Its high-capacity electrical system is protected by waterproof double-lock harness plugs to prevent damage or corrosion – even in the wettest conditions. The machine has a robust X-shaped undercarriage and wide tracks for maximum stability on uneven ground.
“When we purchased the EC220DL 18 months ago, we were even more impressed,” explains Nendah.
“It has increased our productivity by 30% as well as reducing fuel consumption by two litres per hour. This has had a positive impact on our business.”
The EC220DL is an evolution of the popular EC210B-Prime, packed with innovations to improve productivity and efficiency. It features the improved Volvo D6E Tier 2 engine, while improved hydraulics are said to contribute towards improved fuel efficiency, along with Volvo’s patented award-winning ECO mode, as well as shorter cycle times for increased performance.
The cab has been improved to feature a more ergonomic control layout and increased comfort for operators.
Mr Obay has been operating the EC220DL since it was bought, and says: “This is the best 22tonne excavator I’ve ever operated.”
The EC220DL at Alam Jaya CV’s site has clocked over 3,260 hours so far.
Nendah intends to purchase another two EC220DLs within the next year if demand for aggregates continues to rise in the local area.
