The Komatsu PW98MR-8 is a mini excavator designed as a compact construction machine for use in confined spaces. As a representative of the mini excavator class, it combines the maneuverability of smaller units with a substantial weight for this category. The model is manufactured by Komatsu and targets users who require high stability in limited space conditions. The design, with a height of 3,100 mm and a width of 2,350 mm, allows for transport on standard low-loaders, while the overall length of 6,650 mm defines the reach of the working range.
The machine is powered by a four-cylinder diesel engine with a displacement of 3,261 cm³. The tank holds 125.3 l, allowing for long operating times without frequent refueling stops. With an empty weight of 10,000 kg, the excavator is among the heavier models in its class. This weight ensures high stability when digging trenches or moving material. The mass positively affects tipping stability but requires adherence to the permissible gross vehicle weights of the towing vehicles during transport.
Within the mini excavator series, the PW98MR-8 is positioned by its high self-weight and generous dimensions. It is suitable for tasks that require a stable platform for attaching tools such as digging buckets or hydraulic breakers. The dimensions allow for use in areas where lighter machines reach their limits due to stability issues. The combination of compact design and high weight makes it suitable for civil engineering works where precision and stability are paramount.
