From Experiences To Success

Back in the days when Thailand has just entered industrial development era, Dr. Thaworn Phornprapha, Honorary Chairman of Siam Motor Group insisted that Siam Motor took part in the development of the country. He was well aware of how important heavy machinery was for construction. Thus, Machinery Division was established. And it was the first distributor of Komatsu machinery in the world. Later, it was decided that, due to high demand of products, a new, separate company should be founded. Hence, on 7th January 1956, Siam Engineering Co., Ltd. Later, on 18th July 1960, the company changed its name to Bangkok Motor Works Co., Ltd.

With experiences and expertise imparted from both Siam Motor and Komatsu Group Japan, Bangkok Motor Works Co., Ltd. business prospered and grew rapidly in many aspects. Bangkok Motor Works became distributor of many other types of merchandise from both Japan and Europe. In order to make the company runs efficiently, a new company named Bangkok Komatsu Sales was established. It is a joint venture company between Bangkok Motor Works Co., Ltd. and Komatsu Group Japan. The new company, founded on 1st April 2010, provides complete heavy machinery for construction and mining.
