Description
Supply four commercial bricklayers with continuous batches of mortar without taking up excessive jobsite space. The Crown 8S-GH8 Towable Mortar Mixer combines an eight-cubic-foot drum with an industrial Honda GX240 gas engine. Paving and masonry trades mix stone mud and stucco fast. Hand positioning on the dump wheel requires two workers when pouring stiff mixes.
Abrasion-resistant quarter-inch steel forms the eight-cubic-foot mixing drum to withstand sharp sand abrasion. A four-stroke Honda GX240 engine supplies 7.9 net horsepower with reliable overhead-valve efficiency. Dual roller chain drives link the reduction jackshaft to the paddle shaft inside grease-sealed pillow block bearings. A heavy highway axle features leaf-spring suspension and a pintle eye hitch. Unit weight totals 795 lbs with dimensions measuring 50 inches wide by 84 inches long by 55 inches high.
Key Features of Crown 8S-GH8
Commercial masonry contractors buy Crown 8S-GH8 mixers when commercial mortar mixer pricing balances capacity with easy towing. This unit mixes block mortar, brick mud, stone veneer grout, and exterior stucco.
- Eight-cubic-foot steel drum mixes up to two and a half bags of dry mortar per batch.
- Four-stroke Honda GX240 gas engine provides dependable recoil starting and steady mixing power.
- Four adjustable neoprene wiper blades sweep drum walls clean of sticky mortar crust.
- Heavy-duty leaf spring axle protects internal drive chains during highway transit behind work trucks.
- Commercial pintle ring hitch attaches securely to truck pintle hooks for safe highway travel.
- Welded steel safety grate includes an integrated bag splitter to open cement sacks fast.
- Large dump wheel with multi-position mechanical stop controls mud discharge into mortar pans.
Paddle Shaft Torque Load Diagnostics
Bench testing confirms paddle shaft rotation holds at 38 RPM under an 800-pound wet mortar load. The Honda GX240 engine drops 110 RPM when receiving three bags of dry cement mix into wet sand. Drive chain tensioners prevent slack without jumping sprocket teeth under heavy torque loads. Paddle shaft deflection remains under 0.012 inches during severe continuous batching runs. Paddle shaft seal units prevent slurry intrusion during two hours of pressurized hose washdown testing cycles.
Jobsite Operation Drum Care Guidelines
Balanced trunnion pivots let the operator tip the drum with controlled leverage right into waiting mortar boxes. The pintle tongue swings clean of truck bumpers during tight turning maneuvers. Do not buy this mixer for coarse aggregate concrete mixes containing large three-inch crushed rock.
- Grease the drum shaft bearings through grease fittings at the close of every shift.
- Wash drum walls with water and gravel before mortar sets up on the steel.
- Check trailer tire pressure and pintle eye bolts for wear each month.
