Hitachi KH150-3 Crawler Crane (40 tons), manufactured in 1985

Hitachi KH150-3 is a 40-ton hydraulic crawler crane, manufactured in 1985, well maintained and suitable for foundation works, port construction, and heavy infrastructure projects.

Among Hitachi’s hydraulic crawler crane lineup, the KH150-3 is considered one of the most durable and reliable models. With a maximum lifting capacity of 40 tons when using the shortest boom at a 3.7 m radius, this crane effectively meets the demands of complex construction tasks, ranging from foundation works and steel structure erection to port and key infrastructure projects.

The outstanding feature of the Hitachi KH150/180/230-3 series lies in its Japanese manufacturing quality—long-lasting durability, minimal breakdowns, and stable operation even after tens of thousands of working hours. This is why the KH150-3 has remained a preferred choice for major contractors over many decades.

Overall Design and Key Characteristics of the Hitachi KH150-3

The Hitachi KH150-3 belongs to the mid-range crawler crane category, designed to balance lifting capacity, mobility, and structural durability.

• Undercarriage structure: Expandable undercarriage with a width ranging from 3,300 to 4,060 mm, using bulldozer-type crawler tracks with flat shoes, ensuring excellent ground grip even on soft or muddy terrain.
• Hino H06C-T engine: 6-cylinder diesel engine delivering 150 HP at 2,000 rpm. This engine is well known for its durability, fuel efficiency, and ease of maintenance.
• Hydraulic system: Equipped with 2 piston pumps and 2 gear pumps, providing stable pressure and continuous operation, ideal for long-duration lifting tasks.
• Operational safety: Fitted with the Krüger Load Moment Indicator (MARK4 E/2), an advanced safety system of its era, designed to warn operators and prevent overload conditions.

Thanks to this design, the KH150-3 can operate reliably in harsh working environments while maintaining stable performance, making it an ideal choice for projects requiring high safety and precision.

Boom Configuration and Working Capability

One of the key advantages of the KH150-3 is its flexible boom configuration.

• Total boom length: 25 m, including the base section, boom head (10 m), one 3 m section, and two 6 m sections. These components can be combined flexibly to suit various working requirements.
• Example configuration: Base section + one 6 m section + boom head = total length of 16 m, suitable for medium lifting tasks.
• Hook block: Equipped with one heavy-duty hook, capable of handling large loads for steel structures, precast concrete, and heavy infrastructure works.

The KH150-3 delivers optimal lifting performance with shorter boom configurations, while still ensuring safety and stability when operating with longer boom setups, thanks to its balanced hydraulic system.

Winch System and Operating Performance

Winch performance is a critical factor determining construction productivity.

• Main winch lifting capacity: 11 tons, with a lifting speed of 35–70 m/min, ensuring fast and safe hoisting operations.
• Slewing speed: 3.3 rpm, sufficient for maneuvering within confined construction sites.
• Travel speed: 1.5 km/h – not fast, but stable and appropriate for mid-range crawler cranes.

A key advantage of the KH150-3 is its combined mechanical–hydraulic transmission system, which is simpler, more durable, and easier to repair than many modern electronically complex cranes.
