Overview of the Model
The 2004 Demag AC 200-1 is a 220-ton all-terrain crane co-developed by Demag and Terex. AC-series cranes from Demag were designed for versatility in construction, industrial, and infrastructure projects. The AC 200-1 features a main boom length of 223 feet with a quick disconnect system, allowing operators to adapt the boom for different lift requirements. Its maximum jib configuration includes a 108-foot standard jib, a 30–56-foot double swing-away jib, and a 52-foot main boom extension to achieve a higher pivot point for complex lifts.
Specifications and Features
The AC 200-1’s modular design enables rapid configuration for various lifting scenarios. The quick disconnect system reduces setup time when changing between main boom and jib configurations. Counterweight can be adjusted to optimize stability while maximizing lift capacity. The crane’s drive and steering system (10 x 8 x 8) provides exceptional maneuverability on rough terrain, while the 5-axle carrier supports highway transport.
Industry Context and Usage
Demag’s AC series was widely adopted in the early 2000s due to its combination of lifting power and mobility. Cranes like the AC 200-1 are commonly used in industrial construction, bridge building, and wind turbine installation projects. Its robust winch system allows simultaneous multi-line lifts, which increases efficiency on complex jobsites.
Maintenance and Best Practices
Operators report that regular maintenance of winches, sheaves, and boom extensions is critical to prevent downtime. Inspecting drum rotation indicators, hook blocks, and outriggers ensures safety during heavy lifts. Hydraulic system checks and counterweight balance verification should be performed daily. Keeping tires at proper pressure and checking carrier steering components enhances mobility and stability.
Small Story
A crane rental company in Arizona added a 2004 AC 200-1 to its fleet. The crane quickly became the preferred choice for downtown high-rise construction due to its fast setup and 223-foot boom reach. A particularly challenging lift involved installing HVAC units on a 12-story building. By using the swing-away jib and precise counterweight adjustment, the crew completed the lift safely and efficiently, demonstrating the machine’s flexibility in real-world conditions.
Conclusion
The 2004 Demag AC 200-1 remains a versatile and reliable all-terrain crane. Its combination of modular boom configurations, strong lifting capacity, and mobile carrier design makes it suitable for a wide range of construction and industrial applications. Consistent maintenance and operator training are essential to fully leverage its capabilities and extend service life.
