Miner's Crown SE™ is a high-capacity all-steel draft gear certified under AAR specification M-901E. It has an official capacity of 44,980-foot pounds, yet weighs 360 pounds. The housing is designed to carry 2.25 million pounds or 1 million pounds, more than the typical freight car draft lug design load, the company says. The Crown series friction mechanism provides greater frictional resistance during the early stages of compression. Included are wraparound barrier plates that prevent the friction plate from wearing into the housing, replaceable housing wear liners that ensure economical reconditioning, and a full travel release spring for positive release of the friction mechanism, the company says. It is suited for unit train and all other heavy services.
