European railcars began using Miner TecsPak® buffer and drawgear springs in 1979. Buffer springs can be used either as a retrofit replacement in existing housings or as the spring in new buffer constructions. Miner's drawgear springs are available in a number of configurations and capacities, including smaller diameter models used where reduced clearances are present. Since spring designs do not all fall under UIC specifications, Miner can engineer products to meet your unique size, shape, and capacity requirements.
