Why This Unit

Asphalt temperature management hinges on heat retention and discharge control. A hopper that cools material unevenly or discharges inconsistently leaves crews adjusting placement and reheating loads, which compounds labor costs and reduces mat quality. The machine that holds temperature and empties predictably pays for itself in tonnage per day.

Heat retention and discharge control with triple-wall hopper, center heat riser, and recirculating exhaust design

Dual gas-assist guillotine doors deliver consistent material flow onto mat

Electronic thermostat with digital display lets operators dial in 0 to 550 F setpoints

Heated stainless steel shovel platform speeds cleanup between loads

Flush-mounted strobes, stainless tool holders, platform with railing and steps, battery charger, and shovel cleaning compartment included

This new SPH-3.0 pairs a 3.0 cubic yard, 4 ton hopper with dual gas-assist guillotine discharge doors and a triple-wall design featuring a center heat riser and recirculating internal exhaust. The 10 gauge inner tank, 12 gauge heat jacket, and 16 gauge outer shell with 2 inch high-temp fiberglass insulation maintain material temperature across the pour window. An electronic thermostat with digital LED display gives the operator precise control from 0 to 550 degrees F. The heated 1/4 inch 304 stainless shovel platform sits 29 inches from ground, and the tandem-axle trailer with 14,000 lb GVWR and electric brakes with breakaway kit handles highway and site duty.

Right for your operation if you deal with

Cold patches that fail within weeks and waste crew time on re-repairs

Cracks evolving into potholes because regular maintenance falls behind

Utility cuts and patches that don't blend with surrounding pavement

Budget pressure to extend pavement life without full-depth reconstruction
