Tadano AC 5.250L-2 All-Terrain Crane Delivers Unmatched Performance
Tadano has once again pushed the boundaries of crane engineering with the launch of the AC 5.250L-2. This powerhouse of an all-terrain crane boasts a staggering 79-metre main boom, setting a new standard in its class. Whether navigating complex urban lifts or assembling towering cranes, this machine delivers unmatched performance, versatility, and efficiency.
Not only does it offer industry-leading boom length, but its impressive load moment of up to 736 tonne-metres makes it a top-tier contender for heavy-duty applications. Featuring self-erecting extensions and a transport-friendly design, the AC 5.250L-2 is set to become a game-changer in lifting technology.
Class-Leading Boom and Load Moment
At the heart of the AC 5.250L-2 lies its standout feature—the extended 79-metre main boom. This places it firmly at the top of the five-axle crane category. The optional 30-metre main boom extension pushes the total system length to 109 metres, making it ideal for high-rise urban projects and large-scale industrial applications.
Its superior load moment capability allows the AC 5.250L-2 to handle up to 736 tonne-metres with a 7-metre working radius and a 13.5-metre boom. Need even more lifting muscle? Tadano’s optional heavy-lift attachment ups the ante, enabling load capacities of up to 138.7 tonnes when fitted with additional sheaves.
The Perfect Taxi Crane
Designed with mobility and cost efficiency in mind, the AC 5.250L-2 excels as a taxi crane. Its transport configuration ensures seamless road travel without excessive logistical challenges. Featuring a 10×6 drive system, it remains within the 12-tonne axle load limit while carrying a 32-tonne Vario hook block, outriggers, and up to 250 kg of equipment—all within a total weight of under 60 tonnes.
For operations requiring a higher axle load, the 10×8 drive configuration allows a total weight of 82.5 tonnes, accommodating a 12-metre extension, 20 tonnes of counterweight, and up to 500 kg of additional equipment in the rear box. This flexibility ensures easy transportation while optimising lifting potential.
Smart Counterweight Concept for Maximum Efficiency
The AC 5.250L-2’s counterweight system is as sophisticated as its lifting capabilities. With a maximum counterweight of 80 tonnes, the crane can pick up loads in three structured lifts:
- 49.6 tonnes at a radius of up to 6.8 metres (full 360-degree range)
- 15.2 tonnes at a radius of up to 13 metres
- Smaller configurations available, including a 5.5-tonne base plate that can be picked up from 23 metres
Tadano’s IC-1 Plus control system ensures seamless counterweight adjustments, maximising lifting capacity at any slewing angle. No counterweight component exceeds 10 tonnes, allowing for transport via smaller trucks—ideal for tight job sites.
Advanced Technology
Tadano has equipped the AC 5.250L-2 with cutting-edge technology to enhance safety, precision, and efficiency. The IC-1 Plus crane control system continuously calculates real-time load capacities based on the superstructure’s slewing angle. This dynamic feature enables optimal performance, even when the counterweight is reduced or the outriggers are only partially extended.
The Surround View camera system, a standout optional feature, simplifies site positioning. With six cameras, the system provides a computer-assisted display showing maximum outrigger extension widths, eliminating the guesswork. This ensures faster crane setup, reducing delays and improving site safety.
Operator Comfort and Safety Prioritised
Tadano understands that an efficient crane is only as good as its operator. That’s why the AC 5.250L-2 is designed with comfort and safety at the forefront. Noise-emitting hydraulic components are positioned away from the upper cabin, ensuring a quieter workspace. Spacious cabs, well-placed access steps, and secure attachment points enhance safety and ease of use.
Additional features include:
- Pendant lights and load view cameras for improved operational visibility
- Extendable step for easy entry and exit to the upper cab
- Repeater system for wireless camera connection, especially useful when lifting over edges
Eco-Friendly and Cost-Effective Performance
Beneath the hood, the AC 5.250L-2 packs a punch with its 530-horsepower Mercedes-Benz engine, delivering a formidable 2,600 Nm of torque. Compliant with EU Stage V emissions standards, the crane supports HVO fuel, reducing environmental impact.
Tadano’s Eco Mode ensures optimal fuel efficiency, adjusting power output to match real-time requirements. The IC-1 control system also integrates a fuel-saving start/stop function, shutting off the engine when idling to minimise fuel wastage. With a hill start assist, the crane guarantees smooth manoeuvrability, even on inclines.
A Crane Built for the Future
With the AC 5.250L-2, Tadano has taken an already impressive model and enhanced it in every possible way. The extended boom, intelligent counterweight system, and smart crane controls make it a standout choice for urban construction, infrastructure projects, and industrial applications.
Tadano’s legacy of innovation dates back to 1955, when it introduced Japan’s first hydraulic truck crane. Today, the company remains a global leader in lifting technology, committed to safety, quality, and efficiency. With a strong focus on sustainability and technological advancement, Tadano continues to drive the industry forward.
The AC 5.250L-2 isn’t just a crane; it’s a testament to what’s possible when engineering meets innovation.
