For nearly a century, equipment manufactured by Joy Global's (Nasdaq: JOYG) corporate predecessors have been moving earth for a fast-moving mining industry. After all that digging in the dirt, the company is ready to get wet.

Joy Global will acquire equipment maker LeTourneau Technologies from contract driller Rowan Cos. (NYSE: RDC) for $1.1 billion in cash. LeTourneau is principally known as a designer and manufacturer of jack-up rigs for the offshore oil and gas industry, accounting for about one-third of all jack-up rigs presently operating around the world. So for Joy Global, the move represents a bold dive into a brand new niche of the broader resource extraction industry. Perhaps more importantly, following Caterpillar's (NYSE: CAT) landmark acquisition of Bucyrus, Joy Global has now countered the move by securing its own new suite of unique product offerings.

Joy Global has earned Foolish recognition as a proven forecaster of major trends unfolding throughout the global commodities markets. Because of this, Fools will take notice when the company refers to "a new rig build cycle for both offshore and land rigs." Orders for 22 new rigs have expanded the industry's order book already during 2011, while options for 28 additional rigs are suggestive of compelling backlog expansion. As of March 31, Rowan Cos. already reported a total manufacturing backlog of $487.4 million, of which 61% corresponded to LeTourneau's drilling equipment unit.

The remaining 39% of that backlog brings us to the second major feather that is set to land in Joy Global's cap. In addition to drill rigs and related equipment offerings, LeTourneau also manufacturers some of the mining industry's largest and most efficient front-end loaders, including the only wheel-based models large enough to fill the industry's 400-ton haul trucks. In addition, LeTourneau's diesel-electric drive systems make the loaders a compelling choice for miners keen to control rising energy costs. LeTourneau's mining equipment unit will be subsumed into Joy's P&H division.

Instead of locking horns with Caterpillar in a futile campaign to outmuscle the new market-share champion, Joy Global has made what I consider a brilliant move to build a unique suite of product offerings and occupy its own distinct niche among the makers of extractive equipment. The deal restores Rowan to a pure-play contract driller that could pique the acquisitive interest of a suitor like SeaDrill (NYSE: SDRL), while placing oil and gas equipment giants like National Oilwell Varco (NYSE: NOV) on notice that a formidable competitor has arrived on the scene with more than a century of legendary success etched in the earth behind it.
