Launch of the New REGZAM Series

Kato Works, based in Shinagawa, Tokyo, challenges the construction industry with the introduction of their latest hydraulic excavator, the "HD514MR-9," part of the new REGZAM series. Set to be available for purchase in July 2026, the HD514MR-9 is built to meet the growing demands of both efficiency and environmental safety, especially in confined working areas that require careful operation.

Development Background

The construction sector is witnessing an escalating need for machinery that not only reduces environmental impact but also enhances performance in terms of comfort, safety, and maintenance. Particularly in densely populated areas, equipment capable of efficient operation while being considerate of surrounding space has become essential. The HD514MR-9 is designed precisely to address these needs by integrating the much-admired basic performance of its predecessor while offering a compact tail swing ideal for tight job sites. Incorporating new design elements throughout the machine, it achieves improvements in work efficiency, environmental performance, durability, ease of maintenance, comfort, safety, and equipment management.

Key Features

1. Performance Capabilities

The HD514MR-9 boasts a new engine that enhances output and torque, paired with an optimized hydraulic system for a smoother operation experience. Key improvements include:

• - Enhanced Traction: 10% increase in towing capacity.
• - Improved Swing Torque: 18% increase, ensuring more powerful rotations.
• - Increased Work Efficiency: 9% reduction in cycle time during 90-degree swing excavations.

The excavator’s versatility is unparalleled, supporting a wide range of attachments for various tasks.

2. Environmental Considerations

The HD514MR-9 is equipped with a newly developed clean engine that conforms not just to Japan's 2014 emission regulations but also the stricter European Stage V standards. It has achieved the Ministry of Land, Infrastructure, Transport and Tourism's designation as a "Super Low Noise Construction Machinery," producing noise levels significantly below the established standards by over 6 dB. Additionally, it meets the 2020 fuel economy standards, asserting its excellence in fuel efficiency, which is recognized by government certification.

3. Durability and Maintenance

The excavator’s structural integrity is ensured with high-performance sintered bushes at the joints of the boom and arm, increasing grease retention and durability. A redesign of the swing motor has resulted in a 35% improvement in longevity. Maintenance has also been simplified with the integration of various filters within the engine room, streamlining daily checks.

4. Comfort in the Cab

The new cab design enhances overall comfort with an increased forward space that facilitates easier entry and exit. The trusted APC control system remains, allowing operators to adjust work mode and hydraulic flow settings via a user-friendly touchscreen. A split floor mat improves ease of cleaning, making upkeep a breeze.

5. Enhanced Safety

With safety as a priority, the HD514MR-9 features a 7-inch wide LCD monitor with an expanded camera view, improving visibility. The side defroster function ensures clear visibility by directing airflow to the side windows to prevent fogging. Additionally, an optional human-detection surround-view system alerts operators to the presence of individuals around the machine, enhancing workplace safety.

6. Security and Management Features

Incorporating the K-Cast telematics system, the HD514MR-9 allows for remote monitoring of each unit's location, operational status, and fuel levels, significantly improving vehicle management efficiency. This provides optimal planning for site operations and maintenance. The introduction of a new entry system replaces the previous tag authentication with a password input, reducing the risks of tag loss and vehicle theft.
