Gravel conveyors

What Gravel conveyors does

GCI Slingers (legal name Gravel Conveyors Inc.) is a privately held manufacturer and service provider specializing in mobile material placement equipment, headquartered in Zionsville, Indiana with a secondary operations site in Lafayette. The company designs, builds, distributes, and services stone spreader trucks — conveyor-based systems mounted on truck chassis that project aggregate materials (sand, gravel, topsoil, stone, mulch) with precision placement up to 130 feet. Founded in the early 1990s, GCI pioneered the mobile material placement category and has operated continuously for over 30 years, with current ownership acquired by Travis Pettijohn in 2014.

The product portfolio spans branded stone spreaders (Soil King Extreme, Soil King Supreme, The Eliminator, The Cub, and the compact P-Shooter attachment — most built on CanAmerican platforms under an authorized-dealer relationship), the GCI Reloader material handling unit, Bibeau AR-steel dump bodies, and Stout Conveyors' TC-50 telescopic concrete conveyor. Technical differentiation rests on proprietary features including DanFoss-based wireless remote controls, HARDOX 450 steel center frames, beamless live-bottom slinger designs, material-breaking beams for wet/stringy materials, and hydraulic height-adjustment systems. The company is also a parts distributor and authorized service center for multiple makes including CanAmerican, WK Dahms, CAS, and Bay-Lynx, and operates its own aggregate delivery and concrete placement fleets.

GCI generates revenue across six identifiable streams: (1) custom-built equipment sales (one-time, quote-based; $27K–$175K per unit), (2) aggregate delivery services via in-house slinger and dump truck fleet, (3) concrete placement services through the Stout TC-50, (4) parts distribution serving as a stone spreader parts HQ for the U.S. market, (5) truck upfitting and rigging for Class 4+ vehicles, and (6) used equipment resale. Customers span foundation/structural contractors, residential and commercial landscapers, municipal infrastructure projects, septic/utility contractors, and specialty applications (pipeline padding, beach restoration, erosion control), with primary geographic concentration in the U.S. Midwest.
