LOAD & HAUL DEEP IMPACT Maintenance means mileage at Chinese quarry R


esting on the coast of Eastern China is the ancient province of Zhejiang. Situated 60km from the provincial capital,


Hangzhou and 200km from Shanghai, the subtropical region – often thought of as one of the cradles of the Chinese civilisation – of Zhejiang maintains a comfortable distance from the bustling cities on its borders, off ering tourists a cool and lofty summer retreat from the scorching cities. Hidden deep within the dense bamboo forests of Moganshan is Li Yu Shan Mining Co. T e quarrying company is renowned in the region for producing small and medium- sized aggregate of 20-25mm and 50-60mm. A third of its output is used as base material for the thousands of kilometres of high-speed railway tracks that crisscross China. A relatively cheap


commodity, the product sells for 48-50 RMB (€6.5) per tonne.


Beating the odds Li Yu Shan Mining has built a solid reputation in China as a quarrying specialist, producing 1.5 million tonnes of material in 2015. T e company was enjoying steady growth until the Chinese hit the brakes, causing it – and many construction companies – to contract. Because of the relative slowdown and consequent lower utilisation rates of equipment, contractors are tending to keep machines for longer. T e key to customer success when doing this is to take special care of their machines. T anks to sensible routine maintenance and scheduled servicing Li Yu Shan Mining has prevailed, and is again growing its staff of 60 and machine line-up. Since 2010, the company has purchased seven EC210B and two EC240B models from its local Volvo dealer, Zhejiang Liyang Machinery, based in Deqing, Zhejiang.


Digging deep T e EC210B and EC240B excavators are equipped with a high-strength boom and arm, allowing excavating depths of up to 6m. To maintain stability on the rocky terrain, the machines also feature robust X-shaped frames, made of high tensile steel, to ensure a long service life. When purchasing the equipment,


quarry operations manager, Yuan Jian Zhong, was impressed by the good fuel economy off ered by the Volvo B-series excavators. “Volvo excavators typically consume 14-15 litres per hour. When compared to competitor models that often average 19 litres, that translates into considerable fi nancial savings,” he explains. Greater savings have allowed Li

Yu Shan Mining to expand both its operations and fl eet. Recently, the company put down a three million RMB (€400,000) deposit for the fi rst three of a batch of 15 Volvo EC380D excavators for work on an upcoming mining project. Ensuring the machines remain in optimum working condition is the job of Zhejiang Liyang Machinery. Managing the maintenance of more than 1,000 machines in Zhejiang alone, the dealership uses Volvo’s remote telematics, CareTrack, to alert customers of impending maintenance deadlines. “T e technology enables Volvo CE dealers to help customers extract an extra 200,000 RMB (€26,600) out of the lifetime of a machine, even in the harsh conditions of a quarry,” says Cliff Zou, regional service manager at Volvo CE China. As Volvo CE continues to advance its technology, so too will construction companies. Smart solutions, plus the durability and high performance provided by the machines, ensure companies such as Li Yu Shan Mining reap the riches of the deep, with more projects on the horizon. ●
