Meritor Inc. announced its MTA25 low-mount and MTA30 low-mount trailer suspensions are the two newest family members of its Meritor Trailing-Arm Air (MTA) suspension series for North American trailer operators.
The units are specifically designed as part of a fully-integrated system to optimize performance and weight, and are ideal for vocational applications like single-drop flatbed, double-drop flatbed, loggers and chip hauler trailers, according to the company.
The MTA lineup now includes the MTA23 (23,000-lb. capacity), the top-mount MTA25 (25,000-lb. capacity), the top mount MTA30 (30,000-lb. capacity) and the two newest low-mount products. All MTA models are available with the optional lift kit, which the company said is a reliable quick-response system that efficiently raises select axles, improving maneuverability and extending tire life. Available in painted or galvanized finishes, the lift kit attaches easily and can be installed as original equipment or field retrofitted.
“During the last 22 months, we’ve brought five models of trailing-arm air suspensions for trailers to the North American market,” said Craig Frohock, general manager, global trailer, Meritor. “We collect feedback from a variety of sources to ensure Meritor is meeting the needs of its customers, no matter the size.”
“With the last two MTA models in production at our facility in Frankfort, Ky., we’re able to meet all our truck operators’ demands for durability and reliability, plus the key factor of performance in the field,” said Bob Brazeau, director of engineering, aftermarket and trailer, Meritor. “We know fleets want durable and lightweight products.”
According to Meritor, the two new low-mount suspension systems are durable, lightweight and offer the following features: a unique, patent-pending axle-wrap design for a secure and durable axle connection; a patented pivot bushing that absorbs road inputs for a softer ride, more cargo protection and reduced stress on the trailer’s structure; patented steel interleaf shims in the bushing for superior fore-aft stiffness, aiding in improved axle alignment, better tire wear and reduced roll steer; and higher damping shock absorber for improved road-to-tire contact, improving braking and tire life.
The MTA trailer suspension system is integrated with Meritor trailer axles and Q PlusCam Brakes. All are covered by the company’s five-year, 500,000-mile warranty on structural components. Optional components include air disc brakes, automatic slack adjusters, the SteelLite X30 drum and lightweight hub and the Meritor Tire Inflation System (MTIS) by PSI.
