DOWIN International Corp. is a company specialized in manufacturing and export of hydraulic breakers and excavator attachments. It started business in 1999 as a professional component exporter of construction machinery and has been incorporated up to the present since August 2002 due to expansion of business.
DOWIN T series breakers are very powerful and productive thanks to the cylinder embedded control valve system.
DOWIN T series breakers are designed to harmonize the long piston stroke with a nitrogen cushion on the top of the piston, creating less shock and vibration than competing breakers.
Superior quality alloy steel provides excellent durability and longer life. The Box Type breaker was developed to minimize noise during operation, with the use of sound absorbing materials and noise-reducing frame design, which is very useful in the job sites of urban areas. DOWIN T series provides a variety of selections with a diversified range of 14 models.
The pressurized N2 gas in the main power cell is designed to operate with less demand on the base machine hydraulic power. Minimized inner parts facilitate easy maintenance with lower costs.
DOWIN International obtained international certifications such as ISO9001 & 14000, and CE in 2005, Gost-R in 2007, etc. In particular, due to strengthening of business and marketing activities targeting growth areas all over the world since 2005, the export scale of the hydraulic breaker, its flagship item, has been increased year by year.
