### Problem

![Impacting Railcar Opener, Train Car, Material](https://blog.martin-eng.com/hs-fs/hubfs/Impacting%20Railcar%20Opener%2c%20Train%20Car%2c%20Material.png?width=350&height=197&name=Impacting%20Railcar%20Opener%2c%20Train%20Car%2c%20Material.png)Opened in 1999, the CEMEX Cement Terminal in Sacramento supplies cement for concrete and ready-mix operations in central California. Cement is delivered to the terminal by rail from CEMEX manufacturing facilities in California—either from the Victorville plant, roughly 250 miles (640 km) away, or from the Davenport plant, 165 miles (265 km) away. Up to four times a week, the terminal receives unit trains of 40 railcars at a time. Unloading proceeds round the clock, one car every 40 minutes, until all cars are emptied, allowing the train to return to the manufacturing plant for another load. To keep the trains in motion, and the terminal’s five silos—with a total capacity of 8,500 tons—full, it is important that [unloading proceeds smoothly](https://info.martin-eng.com/railcar-resources), which means each railcar needs to be opened and emptied without lost time, safety hazards, or unexpected hassles. Problems in opening the discharge gates of the bottom-dump hopper cars could slow the process. The plant needs a system to make sure the car gates could be opened without the backbreaking labor of using a bar to open the gates or requiring the unloading crew to crawl underneath the car to work on the gate.

Solution

![IRCO_IMG_4527B](https://blog.martin-eng.com/hs-fs/hubfs/iRCO%20-%20Photos%20and%20Campaign%20Items/IRCO_IMG_4527B.jpg?width=350&height=233&name=IRCO_IMG_4527B.jpg)To make sure the railcar unloading proceeds with minimal problems, the terminal uses [Martin® Railcar Openers](https://www.martin-eng.com/content/product/236/railcar-opener) to open car bottom gates. The rugged air-powered Martin® Railcar Opener powers open the most stubborn hopper car gate with 2700 ft-lb (346 kg-m) of torque at 90 psi (6.2 bar). Its adjustable base allows one worker to maneuver the wheeled cart through tight spaces. Use of the Martin® Railcar Opener reduces safety risks for personnel and improves unloading efficiency.

Our unloading crew would surely hate to try to get along without it. We think it’s the best door opener on the market, bar none.”
