Auxiliary arm connecting pin for mobile cranes

We specialize in providing a full range of high-strength pins for construction machinery, compatible with automotive cranes, crawler cranes, tire cranes, truck-mounted cranes, and other mainstream models, covering core application scenarios such as jib pins, main boom pins, and boom section pins. Our pins are made of high-quality high-strength alloy steel through precision forging, heat treatment, and finishing. They feature high tensile strength, shear strength, and wear-resistant stability, enabling them to withstand repeated impacts and shear forces under heavy-load conditions and ensuring safe and reliable equipment lifting operations. We support customization of all specifications and sizes, and can produce precisely according to customer drawings, samples, or specific parameters—from standard models to special-purpose pins for unique working conditions, all can be efficiently arranged. With strict quality control, mature production processes, and rapid response capabilities, we deliver highly compatible, long-lasting pin products to help construction machinery operate stably and reduce maintenance costs.
