Description
Twelve cubic feet of drum volume and a 13-HP Honda GX390 gas engine deliver massive concrete production on highway infrastructure jobs. The Crown C12-CGH13 Pintle Concrete Mixer churns eight cubic feet of wet gravel concrete per batch. Paving outfits pour curbs fast. Manual hand dump wheels require two workers when discharging stiff zero-slump structural concrete.
Quarter-inch high-strength steel forms the twelve-cubic-foot drum shell, reinforced with heavy internal steel mixing blades to withstand coarse gravel scour. An overhead-valve Honda GX390 engine generates 11.7 net horsepower with recoil and electric start. Cast-iron ring gears and steel drive pinions route torque to the heavy trunnion shaft. A heavy highway axle features leaf-spring suspension and a commercial pintle ring hitch. Net tool weight totals 1095 lbs with dimensions measuring 54 inches wide by 90 inches long by 62 inches high.
Key Features of Crown 609492P
Commercial highway contractors buy Crown 609492P mixers when commercial concrete mixer pricing demands maximum batch capacity. This rig pours bridge abutments, highway curb gutters, footing pads, utility vaults, and retaining walls.
- Twelve-cubic-foot heavy steel drum mixes eight cubic feet of wet aggregate concrete.
- Honda GX390 gas engine provides eleven-point-seven horsepower for continuous field mixing.
- Machined cast-iron ring gear and pinion teeth resist abrasive aggregate wear and chipping.
- Heavy-duty steel mixing blades lift stone aggregate to eliminate unmixed sand pockets.
- Large dump wheel with multi-position mechanical stop controls pour speed into crane buckets.
- Leaf spring trailer axle protects drivetrain components during high-speed highway towing behind trucks.
- Commercial pintle ring hitch couples securely to heavy truck pintle hooks for safe transit.
Drum Ring Gear Bench Diagnostics
Tachometers measure drum rotation at 24 RPM under a full 1100-pound wet gravel concrete load. The Honda GX390 engine maintains steady speed, dropping just 85 RPM under peak aggregate resistance. Ring gear backlash measures 0.025 inches on cold bench setup without binding. Trunnion roller bearings show zero axial play after two hours of non-stop load testing. Drum surface temperatures level off at 130 degrees Fahrenheit. Drive pinion seals show zero oil leakage during hot summer bench load tests.
Concrete Usability Drum Upkeep Procedures
The multi-position dump wheel gives the mixer tender mechanical leverage to discharge heavy wet gravel concrete right into wheelbarrows or pump hoppers. The pintle tongue tracks straight behind commercial dump trucks. Do not buy this machine for fine plaster or lime mortar requiring tight rubber paddle wipers.
- Apply open gear lubricant to the drum ring gear teeth each work week.
- Rinse the drum interior with gravel and hose water right after pouring.
- Check trailer wheel lug nuts and tire air pressure prior to highway towing.
