Case Study

Challenge Accepted

When NASA’s prime contractor asked us to increase the payload of the world’s largest self-powered land transport vehicle by 6 million pounds, our team said, “how soon do you need it?”. In the ultimate test of our precision manufacturing and field machining capabilities, L&H completed a retrofit upgrade of the massive NASA Crawler-Transporter 2. And we did it ahead of schedule, on budget, and surpassed the original project specifications.
