Purchase Details
Purchase Details
- Purchase Date: September 20, 2006
- Payment Method: Installments
- Purchase Price: 780,000 RMB, with a 20% down payment and the balance paid in two years
- Reason for Purchase: When choosing an excavator, Mr. Wang considered three brands: Caterpillar, Volvo, and Doosan. Ultimately, he selected Doosan due to its competitive pricing, which offered a faster return on investment and lower risk for a first-time purchase. Over time, he also purchased other models such as the Doosan DH225LC-7, Caterpillar 320D, and Komatsu PC220-8.
- Primary Work: The Doosan DH220LC-7 is primarily used for earthwork and rockwork. Mr. Wang’s machine is frequently employed in road construction and local aluminum mining for rockwork.
- According to Mr. Wang, the Doosan DH220LC-7 operates relatively slowly compared to other machines on the same site, especially when compared to Caterpillar and Komatsu machines. However, overall, its work efficiency is still adequate for most projects.
- Since most of the work is contracted out to the site, with the site covering fuel costs, the Doosan DH220LC-7 has demonstrated good fuel efficiency. Under full load, it consumes 17-18 liters per hour, which is approximately 5-6 liters less than his Komatsu PC220-8, indicating solid fuel economy.
- Engine: To date, the engine has not experienced any major issues and performs reliably.
- Hydraulic System: After 800 operating hours, the hydraulic system showed some oil leakage at the main pump and distributor valve, but it did not affect the machine’s operation.
- Doosan’s authorized dealer in Henan is Qianlima Engineering Machinery Co., Ltd., one of China’s largest equipment dealers. Mr. Wang comments that their after-sales service is generally good, with timely responses thanks to the dealer’s broad coverage. Despite this, most of the maintenance work is done in-house, reflecting the growing scale and professional development of Mr. Wang’s rental business.
- Mr. Wang shared that, with extensive knowledge about his equipment, he no longer relies on the dealer for parts after the warranty expires. Instead, he directly sources parts from subcontracted manufacturers, as many parts are not produced by the original manufacturers but outsourced to third parties. By doing so, Mr. Wang saves a significant amount on parts costs. His strong in-house repair capabilities and deep understanding of the equipment allow him to avoid the high prices set by manufacturers and dealers, which is a lesson worth learning for other users.
- Overall, the Doosan DH220LC-7 is a reliable and stable machine, well-suited for earth and rockwork, especially for those entering the excavator market. While its work speed may not be the fastest, it offers excellent fuel economy, performance stability, and good after-sales service. For new users or small-to-medium businesses, the DH220LC-7 is an excellent option.
