Off road forklifts have good performance and improve efficiency. Compared to traditional forklifts, off-road forklifts have a high chassis, sufficient power, and large size. They generally work in harsh outdoor environments, and there is a risk of tires being punctured during load-bearing operation. The body of a solid tire is made of all rubber, and the tire has strong wear resistance. The solid tires of off-road forklifts have the advantages of small deformation under the same load, good running stability, no need for inflation, and resistance to penetration and wear, greatly enhancing the working time, avoiding tire repair and tire replacement, and delaying labor. The utilization rate and work efficiency of off-road forklifts have been improved. In low-speed and high-efficiency vehicles, solid tires are more advantageous for off-road forklifts. The four-wheel drive off-road forklift has a reasonable structure and strong practicality. The solid tires of the off-road forklift are designed with an advanced three-stage structure, and the three types of rubber materials effectively ensure the overall efficiency of the tires. The foundation with strong rigidity and strength is supported by steel rings inside the rubber, making the tire more rigid and the tire and rim more secure, solving the problem of solid tire slip rings. The middle rubber has full elasticity and efficiently absorbs the vibrations generated during the operation of off-road forklifts, providing forklift drivers with good comfort and driving performance. While reducing vibration, it also avoids damage to the forklifts. The thickened tread layer fully ensures the tear and wear resistance of the tire, and improves its service life. Advanced technology and excellent formula solid tires have a production history of over half a century, with rich experience and advanced technology. The rubber formula has been designed to improve the performance of the tires, reduce the heat and temperature generated during operation, improve the heat resistance of the tires, and thus solve the problems of swelling, slip rings, and burst caused by temperature rise of solid tires.
