What are main features of HZP1600 bridge erection equipment?
HZP1600 segmental assembly bridge erection equipment
HZP1600 bridge erection equipment is designed and manufactured by ZZHZ, using a special method: lift and suspend all segments firstly, then install them in full span. Below are main features of HZP1600 segmental assembly bridge erection equipment
