Designed For Maximum Off-Highway Performance

Link’s TR50-HDT Suspension is specifically engineered for off-highway trailer applications. The suspension is rated up to a 50K capacity with several axle configurations to fit hauling requirements. Haul trucks own the material moving industry, but they’re expensive, need hard surface-maintained roads, and are not suited for distance hauling. Whether you’re taking off overburden, transporting waste, or need to move large material from remote sites to a central processing plant, Link has the trailer suspension for you.

The TR50-HDT trailer suspension was designed to reduce axle and trailer stress, overall weight, and maintenance. The end result is you’ll get maximum performance in the most challenging environments. The 50k capacity rating allows trailer manufacturers to attain a full 150K capacity with a tri-axle configurations. TR50-HDT also provides the highest capacity and range of articulation offered in the air suspension market.

The TR50-HDT suspension was originally designed for tri-axle trailer used in mining and quarry applications. The suspension can also be configured for Super B or two axle configurations if necessary. Because of the wide variations of applications the suspension has been engineered to be customized upon request, but the standard model is designed with a 92.8" axle track. Furthermore, the suspension uses 18" x 7" drum brakes with 14R 25" wheel ends for heavy haul applications.
