Product Description

The Demag AC1200J is a versatile and high-capacity all-terrain crane designed specifically for heavy lifting operations in Japan. This 400-ton capacity crane offers an advanced hydraulic system, exceptional boom configurations, and a robust carrier design, making it a top choice for major construction projects, industrial installations, and infrastructure development.

The AC1200J’s main boom extends from 15.0 meters to 57.9 meters, offering impressive lifting capacities at various radii. At 2.8 meters, the crane can lift 400 tons, while at 12 meters, it still manages a substantial 360 tons. To enhance its operational flexibility, the crane is equipped with two jib options:

Fixed Jib: Extends from 12.0 meters (22.0-ton capacity) to 19.0 meters (16.0-ton capacity)
Luffing Jib: Ranges from 20.0 meters (82.0-ton capacity) to 86.0 meters
The hoist system is optimized for speed and efficiency, with both main and auxiliary hoists capable of speeds up to 160 meters per minute. The boom elevation system allows for quick adjustments between -0.5° and 82° in just 95 seconds, improving operational efficiency. The slewing mechanism provides a smooth 360° continuous rotation at 1.0 rpm, ensuring precise and controlled movements during heavy lifts.

The carrier of the AC1200J is designed for both power and mobility, featuring a 10×8 drive/steering system, which enhances maneuverability in tight job sites. It is powered by a Mercedes-Benz OM443LA turbocharged 10-cylinder engine, delivering 560 HP at 2100 rpm and a maximum torque of 245 kg·m at 1300 rpm. This powerful drivetrain allows the crane to reach speeds of up to 65 km/h, ensuring fast and efficient transport between job sites. The air brake system, electric retarder, and additional braking technologies contribute to optimal safety and control.

Despite its massive lifting capability, the AC1200J maintains compact dimensions for ease of transport and on-site positioning. Measuring 15.965 meters in length, 3.000 meters in width, and 2.719 meters in height, it provides stability and balance while remaining road-friendly. With a total vehicle weight of 41,800 kg, the crane is optimized for efficient load distribution.

The Demag AC1200J represents a perfect blend of power, efficiency, and versatility, catering to demanding lifting operations in Japan. With state-of-the-art control systems, a powerful drivetrain, and advanced lifting configurations, it stands as a reliable and high-performance solution for industries requiring heavy-duty lifting capabilities.
