The Difference Between a Size 50 Saddle And a Size 90 Saddle
The HOWO 371HP head truck uses a 50# saddle, while tractors generally use 50# or 90# saddles. The traction pin diameter of the 50# saddle is 2 inches, and the traction pin diameter of the 90# saddle is 3.5 inches. The 50# saddle can usually tow semi-trailers with a total mass of less than 50 tons. The 90# saddle can tow semi-trailers with a total mass of less than 100 tons. The 50# saddle is suitable for standard load transportation with lighter towing weight or good road conditions, such as urban distribution and general cargo transportation. The 90# saddle is suitable for heavy load transportation and scenarios with poor road conditions, such as mining transportation and large equipment transportation.
