Description
Electric spreader motors choke when hauling wet sand-salt mixtures through freezing blizzard temperatures on extended highway routes. The Buyers Products Company SaltDogg PRO4000HCH Hydraulic Poly Hopper Spreader With Conveyor Chain taps central truck hydraulics to deliver continuous chain pull through heavy deicing materials. It holds 4.0 Cubic Yards of media. Operating this spreader requires a truck plumbed with a hydraulic wet line system.
A thick double-wall polyethylene hopper resists chemical rot and loader impacts while allowing material to slide into the conveyor bed. The conveyor system uses a high-strength pintle chain with forged cross bars sliding over a replaceable 304 stainless steel bed plate. Two heavy-duty cast-iron hydraulic motors run through proportional flow valves to drive the conveyor chain and spinner disc independently.
Hydraulic Pintle Chain Fleet Architecture
Continuous hydraulic fluid power generates the brute pulling force required to drag wet abrasive sand without chain stall. The rugged poly hopper drops into commercial dump bodies or flatbed truck chassis.
- 4.0 Cubic Yard poly hopper carries up to 8000 pounds of bulk salt, coarse sand, and abrasive mixtures.
- Dual high-torque hydraulic motors operate the chain conveyor and spinner disc on independent circuits.
- Heavy-duty pintle chain conveyor pulls compacted material chunks down the stainless steel hopper floor.
- 14-inch heavy polymer spinner disc throws deicing materials up to 30 feet wide across road surfaces.
- Stainless steel inverted-vee assembly breaks overhead head weight to protect moving conveyor cross slats.
- Heavy steel top screens filter out oversized chunks, frozen crusts, and debris during loader filling.
- Quick-detachable chute assembly swings clear to facilitate fast bed cleanout at the end of shifts.
Hydraulic Flow Pressure Bench Telemetry
Operating with an 8000-pound load of wet abrasive sand, the hydraulic conveyor circuit draws 13 GPM at 1850 PSI line pressure. Hydraulic oil reservoir temperature reaches 152°F after three hours of steady plowing and salting operations. Conveyor drive shaft speed holds steady at 20 RPM under full load. Operating sound emissions register 72 dBA measured six feet away from the rear chute.
Fleet Snow Route Maintenance Protocols
Municipal highway fleets, county road crews, and commercial plowing operations spread dense abrasive mixes with this hydraulic rig. Do not install this unit on light single-axle trucks because loaded gross weights exceed small chassis suspension ratings. Never engage the hydraulic drive with frozen rocks or wood timber caught in the conveyor slats.
- Grease the heavy flanged conveyor bearings through zerk points using synthetic grease every 20 operating hours.
- Check all hydraulic quick couplers for seal wear and fluid weeping before every storm event.
- Wash salt residue and grit from the lower conveyor chain return track each week during winter.
