Since the day Leon Wandler and Hank Barney founded the company in 1964—giving the company their initials L and H—L&H Industrial has never stopped looking for new ways to improve our products and services.

From our original roots of a six-man welding shop in Gillette, WY, L&H has grown to an international company with a presence on five continents.

With headquarters still in Gillette, WY, L&H Industrial has facilities in:

  • Sheridan, WY – chroming, hydraulic cylinders and mining equipment repairs
  • Tempe, AZ – gear grinding, heavy manufacturing and machining
  • Tucson, AZ – administration, warehouse
  • Mexico – machining, manufacturing and field services
  • Chile – mining equipment repairs
  • Canada – shovel, drill and dragline parts
  • India – partnered with Vulcan Industrial to offer manufacturing products and heavy equipment

Still a family-run business, the Wandler family holds to the same core pillars that have always provided a solid foundation for the business: safety, quality, service and innovation.

These pillars have guided the business throughout the years and have provided opportunities for expansion into other industries besides mining.

Railroad contracts, construction repairs, heavy manufacturing projects and even NASA contracts have been developed, resulting in an expanded vision for L&H Industrial.

To compliment this growth, L&H is releasing a new brand at the end of the month.

“We’re true to our guiding principles of how we run L&H. I believe that one of the key reasons we continue to grow is that while we focus on providing the most innovative solutions to the mining industry, we’ve expanded into other industries with specialized machinery like the NASA Crawler Transporter 2, and with custom jobs like our complete rebuild of the taconite bucket wheel for the rail industry,” said Mike Wandler, President, L&H Industrial. “We are always looking for ways to improve our processes, designs, service and broadening the industries we serve and our new brand reflects this.”

While progress is exciting, and moving forward with a newly-expanded vision is inspiring, it’s always interesting to look back to see how L&H has become the company it is today.

“After 50 years improving heavy machinery and growing L&H, we have a broader knowledge base, an outstanding talent pool and more state-of-the-art equipment than any we’ve ever had,” said Jeff Wandler, VP, L&H Industrial.

With decades of hard work, dedication to safety and service, and innovative thinking, L&H sees a future reflected by the development of the new brand and new industries to serve and with the same mission and values that created the company in the first place.

 

L&H Industrial Develops Cutting-Edge Gear Grinding Techniques

As seen in the March 2015 issue of Modern Machine Shop, a revolutionary new method of gear grinding is being perfected at L&H Industrial’s Tempe, AZ, facility. In an attempt to eliminate steps and to simplify the gear grinding process, L&H took on the job of grinding gears straight from blanks.

The new grinding process has been increasingly successful with over a dozen gears of all sizes being produced. Utilizing the latest abrasive technologies, the grinding process achieves a high-polish gear quality rating AGMA 14 or higher.

By grinding gears straight from blanks, several steps, such as hobbing and shaping, can be eliminated, saving time and money and increasing efficiency. Gears, some as small as 12 inch pinions or as large as 200 inches in diameter, can be processed in the same way using the Höfler Rapid 6000 6-meter CNC profile grinder.

The Höfler grinder, a German-made, heavy duty machine, was purchased by L&H for the Tempe facility to handle the huge gears often involved in mining operations, some as large as 20 feet in diameter. After installing the Höfler grinder, the L&H engineers began experimenting with grinding gear teeth straight from blanks without overworking the machine, and they experienced immediate success.

The L&H engineers continue to fine-tune the process in the Tempe, AZ, facility, including establishing the tempering procedures that are specific to each job. Carburizing or induction hardening are among the choices for each tempering process, according to the materials and the desired outcome. The gear is then returned to the grinder for finishing, saving a step from the old procedure.

With over 50 years of experience in the mining machinery repair industry, L&H takes on projects large and small. Repairing, gear grinding, welding, machining, heavy manufacturing and more are services offered in the Tempe, AZ, facility. Staff engineers are available to design and reconfigure both new and repaired parts of all sizes. Leading the industry, L&H continues to look for better ways to provide the highest quality services and innovation to the industry.

Crawler Transporter 2 Upgraded in Preparation for SLS Flights

CAPE CANAVERAL, Fla — Officials from NASA’s Kennedy Space Center rolled out the newly renovated Crawler Transporter 2 (CT-2) on Monday, Feb. 23, 2015. The 6.5-million-pound CT-2 will carry a 10.3-million-pound mobile launcher with the 4.4-million-pound Space Launch System (SLS) booster (without liquid propellants), resulting in a massive, 21.2-million-pound vehicle lumbering along to the launch pad at Launch Complex 39B.

For more than two years, NASA’s CT-2 has been undergoing a major overhal in the Kennedy Space Center’s Vehicle Assembly Building (VAB). Recent work has included preparations to install upgraded components that will enable the crawler to carry the greater loads anticipated with the agency’s new rocket designed to take astronauts beyond low-Earth orbit (LEO) for the first time since the early 1970s.

“We removed and replaced the roller-bearing assemblies,” said Mary Hanna, CT project manager in the Vehicle Integration and Launch Branch of GSDO. “These upgrades are designed to make sure the crawler will support us for another 50 years,” she said. “Many of the older parts were wearing out from years of use.”

The renovations were supported by NASA’s Test and Operations Support Contract by Jacobs Technology Inc., NASA’s Engineering Support Contract by QinetiQ Inc., both at Kennedy, as well as Mammoet Inc. of Houston, and L&H Industrial Inc. of Gillette, Wyo.

“L&H is producing the rollers, shaft assemblies, sleeves and other hardware needed,” Hanna said. “Altogether, that amounted to about a half-million pounds of steel being delivered here at Kennedy.”

Technicians from Jacobs performed the work of removing the crawler treads prior to Mammoet jacking and cribbing the corners. L&H then removed the old roller bearing assemblies and inspected the structure and integrity of openings.

When asked how she felt about working on a project that was such a big part of both space history and future missions, Hanna said, “I’ve been working on the crawler for three years now. It has a great deal of history, from Saturn V to Skylab to Shuttle. It was a very moving experience just to be apart of the final shuttle missions and now to prepare the transporter for the future. It’s mind-boggling to be a part of this.”

“There weren’t many changes needed, but the new assemblies will help the crawler carry the heavier load,” Hanna said. “The newer system will also be better lubricated and that should provide a longer operational life.”

NASA has used the crawler since the 60s during the Apollo Program where the massive Saturn V booster would trundle atop the machines out to Launch Complex 39 where the rocket was used to send crews to the Moon. After decades of use, the crawlers have encountered their fair share of wear.

“When you have that much metal-on-metal carrying such huge loads, there is a tremendous amount of heat and friction,” Hanna said. “That creates much of the wear and tear that we see on the crawlers. The improvements will keep the crawler running for a long time.”

Future modifications to extend the lifetime of CT-2′s systems include upgrades to the jacking, equalization and leveling cylinders. This will increase their load-carrying capacity and reliability.

Other work completed includes replacement of electronics, cables, tubing, hydraulic components, as well as cleaning of fuel tanks and hydraulic systems.

If everything goes according to plan, the crawler-transporters will deliver the first SLS to LC-39B in 2018, where it will conduct its first test flight. During this mission, dubbed Exploration Mission 1 or “EM-1,” SLS will ferry NASA’s new crew-rated Orion spacecraft on a journey around the Moon. This is in preparation for missions to an asteroid and, one day, the planet Mars.
