Undercarriage Parts

We continue to supply parts
to support domestic construction equipment quality

Major products

Our high-quality construction machinery undercarriage parts are manufactured using the experience and technologies we have developed over many years. Each part that uses special steel as a material is made using advanced heat treatment, while roller connection areas are made using “friction pressure welding,” which we were the first in the world to develop.

Technology and quality

Taiheiyo Seiki manufacturers products in the pursuit of world-class quality. Our high-quality materials and parts (such as seals) are obtained through our supply chain management system, while our rotating and sliding mechanisms are designed by expert engineers, and manufactured within our manufacturing system that makes use of advanced production technologies and quality management.

An index table is used for automatic delivery during the outer diameter heating, cooling, and inner diameter quenching processes.
A power source with a maximum output of 600 kw is used to quench half the side of a 560 ton lower roller for a 400 g workpiece.
Welding with the rotary table and welding robot synchronized. This results in the formation of clean welding beads.
Two net-type pallets: Capable of processing up to 2 tons. Equipped with a thyristor stack with a maximum output of 90 kw.
A special claw is used to pull the workpiece out, in order to prevent dropping and ensure precision while cutting.
Assembling a lower roller (190 to 800 tons). It is expertly delivered and turned over to improve efficiency and reduce heavy lifting work.
