Product Description

Product Description

Used WA7020-12 Flat-Top Tower Crane

1. Heavy-duty Lifting Performance with Stable 280t·m Moment
Equipped with 12t maximum load capacity and standard rated torque, this WA7020-12 can handle component lifting tasks for high-rise residential buildings, commercial podiums and municipal engineering projects, meeting diverse heavy construction load demands steadily.
2. 70m Long Jib with Strong 2.0t Tip End Bearing Capacity
The 70m-length boom delivers a large coverage range and reliable tip-load performance, reducing repeated equipment relocation on medium-large construction sites, shortening construction cycles and improving on-site operation efficiency significantly.
3. Optimized Flat-top Structure for Urban Dense Construction Sites
Integrated design saves vertical space effectively, avoids collision between multiple tower cranes working at the same time, and is convenient for container shipping, quick assembly and disassembly to lower logistics and labor costs.
4. Intelligent VFD Control System for Precise & Safe Operation
Full variable frequency-drive configuration realizes stable lifting, trolley travelling and rotation action, achieves high-precision positioning, lowers equipment wear and energy consumption, and improves the safety coefficient of long-time continuous construction work.
5. Inspected Second-hand Equipment with Complete Export Certifications
The used WA7020-12 has passed comprehensive inspection and fault detection before delivery, with intact CE certification and customs-clearance documents, stable mechanical performance and reliable after-sales support for overseas project delivery.
