SPI Mobile Pulley Works

What SPI Mobile Pulley Works does

SPI Mobile Pulley Works (DBA Mobile Pulley) is a privately held U.S. industrial manufacturer founded in 1892 and headquartered at 905 South Ann St, Mobile, Alabama. The company designs, engineers, and manufactures dredging equipment — principally dredge and slurry pumps, dredge cutters, complete dredges, and complementary components such as ball joints, gears and pinions, and dredge pipe — using its proprietary Moballoy White Iron alloy for abrasion resistance. It serves five end-markets globally: dredging, maritime, mining, aggregates, and energy.

The business is vertically integrated under a single roof in Mobile, with a foundry capable of pours up to 100,000 lbs in cast steel and White Iron alloys, a 65,000 SF machine shop handling parts up to 20 feet in diameter, a 39,000 SF fabrication facility, a 100,000+ SF pattern shop, an in-house design and engineering function, and a field services group deployed worldwide. Revenue is generated through direct enterprise sales of custom-manufactured hardware (dredges, pumps, cutters, components) and project-based professional services (foundry casting, machining, fabrication, design/engineering, on-site field service). Pricing is not publicly disclosed and is presumably quote-based given the custom, project-specific nature of orders.

The company employs 51–100 people and markets itself primarily through its long-standing brand (since 1892), its professional website, and direct enterprise field sales rather than third-party distribution. No public revenue, ownership, leadership, or financial information is disclosed in available sources, and there is no evidence of recent funding, M&A, or material corporate actions; the apparent emphasis has been on steady operation, brand refresh (2024 logo and website), and continued worldwide field service expansion.
