Hatch Covers
The longtime leader in hopper car outlet gate design and manufacture, we now cover the car from top to bottom. Introducing DuraShield™ hatch covers, available in both round and square end-cover configurations to accommodate most 24" trough designs and are available in all standard lengths. The DuraShield is constructed of a high performance aluminum composite material (aluminum skin top and bottom and a solid polyethylene core) over a rigid frame. The result is a lightweight profile cover system that is more durable than fiberglass and lighter weight than all-aluminum hatch covers.

Miner offers a complete line of Brake Beam components. They include Miner Series 2008 brake beams – they last 10x longer than non-bushed beams for prolonged service life and better braking performance, and brake beam wear plates and connectors - ruggedly designed for enhanced railcar value and long-life performance.

TecsPak® Springs
TecsPak® is Miner's patented elastomer spring material that is used in draft gears, constant contact side bearings, and springs in European UIC buffer and drawgear applications. TecsPak® absorbs more energy per weight or volume than comparable rubber, urethane, or steel springs. It is extremely durable, resistant to dirt, lubricants, fluids, and most solvents and is virtually maintenance free while in service.
