To ensure the normal operation of construction machinery, new processing and assembly of parts, there is a bias geometry and with the size of the initial application, due to shock, vibration, and other small alternating load double drum compactor, and the impact of heat, deformation and other factors plus excessive wear and tear and other reasons small roller, easy to make the original fastening parts loose. Unique steering in corrective institutions, can facilitate the realization of the template parallel to the direction of travel; 5, full hydraulic design reasonable driving small roller from the head office, make the operation convenient, comfortable, easy, comfortable. Bearing bits of each roller shaft primary processing by the large lathes, to ensure concentricity of the rollers, smooth pavement of dual-drive dual vibration small roller, Shandong Jin Heavy Industries (certified), Ziyang small roller by the Shandong Jinzhou Heavy Machinery Co., company. Heavy Machinery Co., Ltd. Shandong Jin (www.dajinzg.com) Shandong Jining, compaction machinery leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In Shanxi, Shandong Heavy Industry leadership with the staff warmly welcome all inquiries negotiations to create Shandong Jin Heavy better future.
