Kato's large excavator range provides the smartest solution that combines quality, durability, and innovation to get the job done right.
Kato's large excavator range, particularly the HD820-7 and HD823MR-7 models, represents the pinnacle of Japanese engineering in heavy-duty machinery. Designed for maximum efficiency and power, these excavators are ideal for large-scale projects, including mining, demolition, quarrying, and civil infrastructure. They offer a blend of robust performance, advanced technology, and operator-focused design that sets them apart from the competition.
The Kato HD820-7 is a conventional-tail excavator with an operating weight of approximately 21 tonnes. It's a true workhorse, built for demanding tasks that require immense digging force and stability. Equipped with a powerful Isuzu engine, the HD820-7 delivers high torque and horsepower, ensuring it can handle the toughest materials with ease. Its conventional design provides a larger counterweight, which in turn offers superior lifting capacity and stability for heavy-duty applications.
This model is known for its fast cycle times, improved over previous models, and a highly responsive hydraulic system. This allows operators to complete tasks faster, boosting overall productivity on the job site. The HD820-7's heavy-duty undercarriage and large-capacity bucket options (0.45 - 1.10m³) make it a reliable choice for bulk earthmoving and large-scale excavation.
The Kato HD823MR-7 is the perfect solution when you need large excavator power but are restricted by space. This model features a compact-radius or "reduced tail swing" design, meaning the rear of the machine stays within the width of its tracks as it rotates. With an operating weight of around 23 tonnes, the HD823MR-7 packs significant power into a more manoeuvrable frame.
The HD823MR-7 is specifically designed for urban construction, roadwork, and projects in congested areas where a conventional excavator would be too large. Despite its compact design, it doesn't compromise on performance. It boasts an even greater improvement in cycle time compared to its predecessors, making it highly efficient. The machine's stability is enhanced by its design, allowing it to perform a variety of tasks, from trenching and grading to demolition, with precision and control.
Both the HD820-7 and HD823MR-7 share a commitment to operator comfort, safety, and modern technology. They feature a redesigned cabin that meets ISO safety standards, offering enhanced visibility, improved ergonomics, and a comfortable, climate-controlled environment. The new cabin design includes a user-friendly LCD touchscreen monitor, making it easy to access machine data and control settings.
Maintenance is also a key consideration in the design of these models. They feature wide-opening access panels for simple and safe servicing of filters and other components. The new engine start mechanism and standard rear-view camera further enhance safety on the job site. The use of an eco-friendly, Tier 4 compliant engine and an SCR system reduces emissions, making these large excavators a responsible choice for modern projects.
Whether your job demands the sheer power and lifting capacity of the HD820-7 or the agile, compact performance of the HD823MR-7, the Kato large excavator range provides a solution that combines Japanese quality, durability, and innovation to get the job done right.
