Technical Parameters

Parameters


Lifting performance:


Lifting capacity and reach: The maximum lifting capacity is 12 tons, the maximum lifting capacity is achieved at a reach of 19.7 meters; the maximum lifting capacity at the end of the boom is 2.5 tons, which is well adapted to the task of lifting heavy objects at different distances and can be used to lift heavy objects.


Lifting moment: The maximum lifting moment can reach 300 ton meters. The strong lifting moment can meet the needs of lifting heavy objects.


Working radius: The maximum working radius is 70 meters. The crane boom changes every 2.5 meters, and there are 17 combinations of boom length from 30 meters to 70 meters, which can adapt to the needs of different working radii and has high flexibility and adaptability on the construction site.


Working speed:


The maximum lifting speed can reach 95 meters per minute.


The luffing speed is 0-75 meters per minute.


The rotation speed is 0-0.8 revolutions per minute. Fast working speed can improve construction efficiency and shorten the construction period of the project.


Independent height: The maximum independent height reaches 60 meters.


Structure


Strong mast: The mast is made of high-quality steel and advanced manufacturing technology, has a strong and stable structure, can withstand large wind and gravity loads, ensuring safety in the construction process.


Convenient installation and dismantling: This tower crane is a flat-topped tower crane, compared with the tower crane with a turret, the installation and dismantling is more convenient and fast, which saves time and labor in construction.


Other features


High versatility: Zoomlion tower crane products have a large number in the market, and the parts of the WA7025 - 12 model also have good versatility, it is easy to find compatible spare parts in the market.


Outstanding features: The structure is simple, has excellent balance and stability, outstanding load-bearing performance, widely used in the construction of civil buildings, power facilities, bridges and other construction fields.
