[Reduce Risk Before Excavation!] Nishio Rent All Begins Rental of Buried Object Detection Sensor-Equipped Excavation Bucket "LDR EXCAVATE™"

Nishio Rent All Co., Ltd. (Headquarters: Osaka City, Osaka Prefecture; President and Representative Director: Kimishi Nishio; hereinafter "the Company"), a subsidiary of Nishio Holdings Co., Ltd., has commenced rental of the 'LDR EXCAVATE™' excavation bucket equipped with a buried object detection sensor for underground excavation. This product was developed by RodRadar (Headquarters: Israel; CEO and Co-Founder: Moshe Dalman).

Furthermore, this product will be introduced at the 8th International Construction & Surveying Exhibition (CSPI2026), to be held from Wednesday, June 17 to Saturday, June 20, 2026.

■ Unabating Damage to Buried Objects During Excavation

In 2022, a large-scale power outage occurred in Yokohama City, Kawasaki City, and other areas, affecting approximately 69,000 households. It was revealed that the cause was damage to underground power transmission lines during waterworks construction carried out that night.

Additionally, according to the "Status of Underground Buried Object and Overhead Wire Accidents Accompanying Construction Work in 2024" published by the Japan Federation of Construction Contractors in May 2025, 168 buried object accidents occurred nationwide in 2024, an increase of 8 from the previous year. This indicates that such accidents can occur at any worksite.

Accidents involving water pipes and power cables, in particular, not only cause work stoppages and increased repair costs but also inflict severe damage on local residents and lifelines.

■ Achieving Safe and Reliable Excavation Work

Buried object contact accidents, which have a significant impact on construction sites and surrounding areas, are often caused by insufficient checks or the assumption that "it will be fine."

While it is important not to rely too heavily on drawings and to confirm, mark, and share information on-site, construction sites are bustling with people and information. With tight deadlines, ensuring all steps are reliably executed requires significant effort.

The solution to this is the buried object detection sensor-equipped excavation bucket 'LDR EXCAVATE™'.

This system incorporates RodRadar's proprietary patented technology, the ground-penetrating radar system "Live Dig Radar (LDR)," at the bottom of the bucket, enabling real-time automatic alerts on-site. It warns the operator of the location and depth of buried objects. This enables safe and reliable excavation work.

*Detection may not be possible depending on the condition of the buried object, soil type, etc.

■ Features of LDR EXCAVATE™

① Issues a real-time warning to the operator when a buried object is detected

② The operator can easily check the excavation status using a dedicated tablet

③ Reduces the risk of work stoppages and schedule delays due to damage to buried objects

■ Reducing the Risk of Common Major Accidents with the Latest Proprietary Technology

This system is already in use at many sites overseas. The Company is the first to handle it in Japan.

For the common risk of buried object damage accidents, the latest proprietary technology can mitigate risks that cannot be addressed by human effort alone.

The Company will continue to propose new technologies and products from an on-site perspective to address potential dangers at construction sites.
