The principle of the traction pin conversion device: the tractor equipped with the No. 50 traction seat can meet the traction of the semi-trailer with the No. 90 traction pin and the semi-trailer with the No. 50 traction pin through the conversion device of the traction pin.
The specific design of the conversion device: It is composed of two semi-cylindrical sleeves, which are buckled axisymmetrically on the traction pin of the No. 50 semi-trailer, and fixed with a thin iron wire with a diameter of 3 mm in the slot, so that the No. 50 traction pin can be quickly realized Conversion to No. 90 traction pin. The installation and disassembly are simple, convenient and fast, which not only improves the versatility of the tractor, but also improves the work efficiency.
