We bought 6 sets crawler excavator and 3 sets wheel excavator in June and just got them last week. I strongly recommend purchasing excavators from Shandong hengwang group. They have a complete excavator after-sales service system and a complete range of excavator products, mainly mini excavators, wheel excavators, and crawler excavators, with superior performance, strong operability and high quality. The picture shows us how we operating a crawler excavator.
