There 45,65,95,125,180,225,250 type, chain width according to user requirements, the bending radius from between 50-800. There are three forms of the support plate. (1) When the towline need carry large pipe, cable load should be used in high-strength support plate - piece (2) When the umbilical fitting size larger than the pore size of the support plate cavity or require frequent disassembly, repair isochronous. Optional support plate - Divided (3) Installation umbilical many varieties, the choice of the support plate - frame type steel towline outer diameter of 95 manufacturers phone | Xin Wantong Machinery (certified) | towline By Xin Wantong Machinery Co., Ltd.
