Introduce the design of construction machinery tire for 12.00-20NHS 20PR girder. Structural design: The outer diameter of the tire is 1132mm, the width of the tire is 278mm, the width of the driving surface is 250mm, the diameter of the bead is 513mm, and the depth of the pattern is 26.5mm. Construction design: The tire tread is formed by layer paste. The carcass curtain and cushioning layer are respectively made of 11 layers of 1400dtex / 3V1 and 2 layers of 930dtex / 2V3 nylon 66 cord. The diameter of the molding head is 690mm and the dual-mode vulcanizing machine is vulcanized. Finished tire inflatable rim size and physical properties in line with national standards, the use of good performance.
