lorry crane

1)high strength steel plate leads the crane to high lifting capacity and light self-weight.
　　2)sand blasting on whole steel structure.
　　3)different steel plate thickness of the boom section make the boom much high stength and reduce self-weight.
　　4)big nylon slides reduce wear and tear,in the meanwhile reduce mainternace.
　　5)inherent telescoping system make the chassis of the truck.
　　6)three point bridge support can protect the chassis of the truck.
　　7)the end and the head of the boom are designed more compact,so as to make the boom overlap length more longer.
