The structure of the engineering plastic towline towline shape like a tank chain by the of many unit chain section between the chain rotate freely. Same series towline high, outside the same, pitch, high towline, the bend radius R can have a different choice. Unit chain around the chain plate and the upper and lower cover, towline each section can be opened, easy assembly and disassembly without threading, open the cover to the cable, tubing, pipe, etc. into the towline. Engineering plastic towline basic parameters: feed towline model internal height and the internal width determined towline Model, according to outside high and outside width of the basic parameters of the material of the plastic towline: reinforced nylon, with a high the pressure and the tensile load, good toughness, high flexibility, abrasion resistance, flame retardance. High and low temperature stable performance, can be used in outdoor. Anti patience: oil, salt and acid, alkali capacity. Running speed and acceleration: a maximum speed of 5m / s, the maximum acceleration of up to 5m / s 2 (specific speed, acceleration, as the operation may be.)
