At bauma 2025 exhibition, Hitachi Construction Machinery's special application equipment may become a bright spot. Hitachi Construction Machinery will collaborate with KTEG to showcase six specially modified excavators to meet specific application needs such as demolition, dredging, and underground excavation. Firstly, the excavator ZX250LC-7 super long arm is assembled at Hitachi Construction Machinery Europe's factory in Amsterdam. This model is designed specifically for dredging, loading, and slope finishing. The design of its large and small arms combines strength and flexibility, allowing the equipment to have a working range of up to 18m. The grab boom equipped on the second-hand excavator ZX350-7 is produced by Hitachi Construction Machinery in Japan. Its maximum operating depth can reach 30m, making it an ideal choice for underground excavation. With an enhanced hydraulic system, the equipment operates smoothly and efficiently, which can improve the productivity of complex excavation projects in cities. The grab bucket telescopic arm has high-speed telescopic function and strong traction force, allowing it to operate efficiently in narrow spaces. Unlike standard excavators or long arm excavators, it requires minimal rotational space and is an ideal solution for compact work environments.
