The Tadano AC 5.250‑2 is a 300 US‑ton all‑terrain crane combining exceptional lifting reach with modern controls. It features a Mercedes‑Benz diesel engine in compliance with stricter emission standards, the advanced IC‑1 Plus real‑time load control system, and versatile transport configurations. It is engineered for high efficiency, operational flexibility, and safe performance across demanding job sites.

Key Features:

• IC‑1 Plus crane control system that calculates safe lifting capacity in real time based on boom angle and slewing position.
• Self‑rigging main boom extensions (from ~44 ft to ~229.6 ft) with optional HAV extension adding ~138 ft extra reach.
• Eco mode and start/stop engine function to match power output to load demands and reduce fuel use.
• Asymmetric outrigger extension capability (0 %, 25 %, 50 %, 75 %, 100 %) for flexible setup in constrained sites.
• Payload‐capable rear end and counterweight mounting options that support versatile configurations within road axle load limits.

Safety Features:

• Surround View camera system (six cameras) offering a 360° visual of the crane’s surroundings for safe positioning.
• TailGUARD active backup assist (ultrasonic sensors, automatic braking) when reversing to avoid collisions.
• Hill start assist to prevent rollback on slopes during travel.
• Quiet cab environment by locating hydraulic noise sources away from the operator’s space.
• Strategically placed access steps, secure points for personal safety equipment, and retractable steps for safe cab entry/exit.

Transport Specifications:

• Can operate under a 12 tonne (≈ 26,500 lb) axle load configuration, enabling taxi‑crane travel without support vehicle for certain equipment loads.
• Counterweight modular design allows split transport loads (e.g. 54.7 t in one lift and smaller loads) to respect road limits.
• Carrier drive/steering on 10×6×10 (with optional 10×8×10) across five axles for optimized mobility.
• Overall transport dimensions: length ~51.6 ft, width ~9.8 ft, height ~13.1 ft.
• Use of 16‑inch steel rims supports operation within legal road axle load limits.
