Link Mfg.’s TR50-HDT heavy-duty off-highway air-ride suspension offers an added level of choice to fleets that do some heavy lifting off the highway.
Outfitting trailers with a tri-axle walking beam suspension exposes the equipment to jounce, rebound and other dynamic stresses on uneven terrain. Lower-capacity air-ride suspensions are an option, but the quad configurations needed for heavier loads imposed their own stress-inducing forces associated with wheel drag and scrubbing tires, the company says.
The TR50-HDT, in a tri-axle configuration, combines the ride characteristics of an air-ride but at a lighter weight than a quad.
It’s designed for a 17-inch ride height with +/- four inches of travel, but available in other ride heights on request. The maximum axle spread is 60 inches at its 50K capacity, and it can operate up to 65 km/h.
Each TR50-HDT has three high-capacity air springs, with the performance further renhanced with heavy duty shocks that minimize the forces that can damage trailers, axles and wheel ends. Additional shocks can also be added if needed.
It comes fully integrated with a six-inch solid round KGI axle. The 92.8-inch axle track incorporates 14R 25-inch wheel ends and 18-inch drum brakes.
