Product Feature

1.Back luffing structure of double large triangular mast,At the same time, it has the super-high rock entry stability of double large triangular amplitude and the convenience of transfer transportation of parallelogram amplitude.。

2.Large Mast Section、Large diameter slewing bearing、Reinforced chassis,Make the machine structure more stable,The bearing capacity is stronger。

3.Three power head reducer,The torque is large,High reserve factor,Construction capacity is stronger。

4.2. Power matching and limit load control technology、Multi-gear power head、Two-speed pressurized cylinder,More efficient construction。

5.Main winch with central single-row rope、One simple and two machines,Better lifting ability;Single layer wire rope,**And the service life of the steel wire rope is greatly prolonged.。

6.Adopt a new generation of cab、New human-computer interaction interface,Good sight、The operation is more comfortable。

7.New generation of electronic control platform,360-degree full-view monitoring,Cell phoneAPPPush device information,Safe and convenient。
