Nachi-Fujikoshi Group Expands Hydraulic Machinery Business for the Utility Construction Machinery Manufacturers

Strengthening the Production System at Nachi Tohoku Seiko

Nachi-Fujikoshi Group will strengthen its supply system for utility (small construction machinery) makers in order to build a firm position as a top-level hydraulic equipment maker in the global utility construction sector. Under the plan, the company will develop a system to supply rotary center joints in addition to hydraulic drive motors, swing motors, and piston pumps, emphasizing the supply of these products as one set.

As a part of this plan, a new plant will be built at Nachi Tohoku Seiko in Yamagata Prefecture that is a major manufacturing base of hydraulic equipments for the Group. This will expand production lines of rotary center joints to meet the growing demands for utility construction equipment. Rotary center joint is a precision hydraulic device (i.e. rotating hydraulic joint) that can smoothly and efficiently circulate hydraulic fluid without any loss at any swing angle of the cockpit (operator’s seat). This is due to joining the gap between the hydraulic pump in the cockpit that can rotate 360 degrees, and the hydraulic motor in the crawler.
