We are pleased to announce that Nippon Sharyo, Ltd. (Headquarters: Nagoya, Aichi; President & CEO: Mamoru Tanaka; hereinafter referred to as “Nippon Sharyo”) and DeepX Inc. (Headquarters: Bunkyo Ward, Tokyo; President & CEO: Joji Toyama; hereinafter referred to as “DeepX”) have agreed to collaborate on system development aimed at the automation and manpower reduction of the Casing Rotator (hereafter “RT”), a core product in the construction equipment business of Nippon Sharyo.

1. Overview of RT
The RT, or Casing Rotator, is a construction machine used in deep foundation work, specifically developed for the fully cased drilled shafts. It is capable of safe and efficient drilled shafts construction under harsh drilling conditions, such as boulders or existing reinforced concrete foundations of old structures. In recent years, the RT has been utilized not only for drilled shafts construction but also for steel rotation in pile methods and obstacle removal operations, serving a wide range of foundational construction tasks.

2. Development Overview
The RT is often used in tough environments, such as hard stratum or layer with underground obstructions. These conditions frequently cause significant fluctuations in drilling load, necessitating highly skilled operation techniques. The know-how related to this operation tends to be tacit knowledge among operators, presenting challenges in skill transfer and perpetuation. Moreover, the decreasing population of working-age individuals poses a significant challenge in finding successors for machine operators.
To address these issues, Nippon Sharyo, which specializes in the design and manufacturing of construction machinery for foundation work, and DeepX, known for its automation technology in construction machinery, will leverage their respective areas of expertise to develop an automated construction system for the RT that can be used for fully cased drilled shafts. This initiative will also help to mitigate the challenges posed by the aging skilled operator workforce and the shortage of operators due to demographic changes.

3. Future Prospects
Moving forward, the plan is to continue development with the goal of implementing the automated construction system by 2026. By introducing automation technologies into construction machinery, we aim to enhance productivity at construction sites and promote sustainable development.
