Kobelco KMG6300

The Kobelco KMG6300 is a 300-tonne capacity all-terrain crane, uniquely designed in partnership with Manitowoc under an OEM supply agreement, wherein Grove’s all-terrain cranes from the Deutsche Grove plant in Wilhelmshaven are rebranded for exclusive sale in Japan. The KMG6300 is based on Grove’s proven GMK6300L platform but has been customized to meet Japan’s stringent regulatory, operational, and transport requirements. It features a 6-axle all-terrain chassis and integrates a special boom structure that improves lifting performance while ensuring compatibility with Japanese road and site conditions.

The main boom extends to 80 meters, and when paired with a hydraulic luffing jib (12.5 to 37.3 meters), the maximum lifting height exceeds 115 meters. The crane is driven by a high-power 530 HP (395 kW) Daimler-Chrysler OM502LA Tier 3 diesel engine, while crane operations are powered by a separate 175 HP (129 kW) OM926LA engine. The drivetrain includes a ZF TC Tronic automated transmission system and hydro-pneumatic suspension for stable travel and ease of transport across various terrain.

Notably, the KMG6300 is engineered for ease of disassembly and reassembly to facilitate efficient road transport within Japan’s strict size and weight limits. It also supports interchangeable counterweights, including compatibility with other Grove crane models such as the GMK5180-1, GMK5200-1, GMK5250L, and GMK6300L, maximizing logistics and fleet flexibility.

As a Japan-exclusive model, the KMG6300 showcases Kobelco’s commitment to local market needs with advanced safety systems, intuitive operator controls, and refined lifting configurations suitable for demanding urban and infrastructure construction projects.
