The asphalt aggregate hopper, road oil tank and heat transfer oil tank are fully insulated with 2' industrial, high temperature 12R factor insulation encased in a double steel jacket. The top cover on the unit is an Optional double form fitted 2' insulated tarp, capable of sustaining 500° F., OR Optional Hydraulic Operated Steel Top Doors.
Hopper capacity, depending on model, will be 4.25, 5 or 6 cubic yards.
The heat transfer oil tank and asphalt aggregate hopper shall be heated by a submerged retort tube with vertical exhaust stacks. The burner is a 2 stage 200,000 BTU vapor propane that is thermostat controlled and regulated to light on 5 ounces and advanced to a 10 PSI high burn. The ignition system is 12 volt DC with electronic ignitor. Gas burner has safety shut-off on loss of flame or excessive temperature. Thermostats will be 0/300° F. solid state.
All electronic controls will be solid state shock resistant. Thermostat for tack oil tank is 50/200° F. All thermostats have built in high limit safety shut down switches. Same thermostat controls the 12 volt LP Gas fired system and the 220 volt electric heating system.
LIQUID ASPHALT OIL TANK CAPACITY AND HEATING SYSTEM
For tank capacity refer to models available. The tank has a double steel jacket with 2' insulation. The tank is equipped with a heat transfer system with an adjustable temperature valve that is capable of heating the emulsion oil from 0 to 150°F, using the truck engine coolant system as the heat source. The liquid asphalt pump and all lines are in an insulated heated area with a pick up tube 1' off the bottom of the tank with a 2' gate valve drain. The tank has a 220 volt thermostat controlled dry well NEMA explosion proof dry well electric heater and a hot well for storing spray wand in cold weather. For ease of maintenance or change out of heater, tank does not have to be drained. For capability of working cut back oils, tank is available with an optional 150,000 BTU lp gas retort tube burner regulated @ 10 psi, thermostat controlled, 12 volt dc electronic ignitor with safety shut-off on loss of flame.
HEAT TRANSFER OIL SYSTEM
Tank capacity is 220 gallons with a 1' circulating pump. Pump is self priming, variable speed, ball bearing, rotary gear and operates at 10 GPM at 1400 RPM. Pump is thermostat controlled and will automatically circulate when the burner is fired. NO MANUAL input required. The pump will retire when the burner shuts off. This allows the operator to heat materials while unit is working or in transit. This system drastically increases the life of the heat transfer oil, protects the retort tube from over heating and prevents coke build up in the tank.
ELECTRIC HEATING SYSTEM
The asphalt aggregate hopper and liquid asphalt tank is heated by a 220 volt, 62kw OSHA required NEMA explosion proof immersion heater, thermostat controlled with 25’ of cord with dual in-line 30 amp fuses with MOV 220 VAC surge absorber. The heating system is capable of maintaining heated material during non-working hours.
Optional 35 or 50 gallon frame mounted LP gas bottle with quick fill connector, 10 psi regulator and fuel sight gauge OR Optional 100 lb (25 gallon) removable propane bottle, complete with 10 PSI regulator.
LIQUID ASPHALT OIL PUMP
A hydraulically driven, 1 1/2' self priming, variable speed, reversible, rotary gear pump with relief valve. Operating at 20 GPM at 1200 RPM, 100 PSI. The pump will circulate the emulsion oil to prevent separation and to crush any lumps that may form and cause clogging of the spray tip. Air injection systems do not have this capability.
We offer optional; Stanley BR45, 72, 67 and 87 Pavement Breakers, complete with quick couplers, asphalt cutter, tamper and detachable shank with lockable transporting bracket.
LIQUID ASPHALT HAND SPRAYER
A 5’ x 3/8' wand, equipped with fan nozzle and Deadman Control Valve. Sprayer hose is 15’ x 1/2' with a reversible pump and diesel flush system for cleaning pump and lines.
The pump is gear type, variable speed at 12 GPM and has an operating pressure of 2000 PSI at 900 RPM.
HYDRAULIC OIL RESERVOIR
30 gallon capacity with sight and temperature gauge, ventilated fill cap, 150 micron sump strainer and a 10 micron return filler.
HYDRAULIC OIL COOLER
An AKG fifteen tube hydraulic oil cooler with shroud. The fan cooler operates on 12 volt DC and is thermostat controlled at 115° F.
HYDRAULIC HOSE AND FITTINGS
All high pressure hoses and crimped fittings have a minimum of 9,600 PSI burst pressure.
HYDRAULIC CONTROL VALVE
Five spool, two way, variable flow with 2200 PSI relief valve. The valve controls hydraulic screw conveyor, hydraulic doors, asphalt agitator, liquid asphalt pump and tool circuit. The valve has an internal or external safety design that will protect the operator and not allow the screw conveyor or asphalt agitator to operate when the doors are open. This system is designed to divert hydraulic oil pressure back to the tank. Electronic solenoids on hydraulic valve are not acceptable due to mechanical override feature and ease of bypassing system. The valve is operated from the rear of machine by remote levers. To reduce maintenance problems the main directional control valve stack has no electric solenoids.
10’ long by 6' diameter progressive screw conveyor has hard surfaced flights welded continuously on 2' scheduled 80 pipe and is ball bearing mounted. Conveyor is driven by a 9200 in.lb. torque variable speed hydraulic motor with forward and reverse. Unit shall have a delivery chute with 120° of pivot. All bearings can be greased from ground level. A replaceable insert liner is skip welded the full length of main asphalt aggregate hopper beneath screw conveyor.
The unit has two 3' dial type, stainless steel temperature gauges that constantly monitor the temperature of the road oil and heat transfer oil.
For drying off repair site and cleaning hand tools, The unit has a 200,000 propane BTU hand torch with shut-off valve and 10’ of hose. Hand torch has mounting bracket for transport.
The agitator shaft is built into the premix hopper and designed to break up asphalt bridging due to vibratory compaction. The scheduled 160 shaft has 12 spikes and is ball bearing mounted and driven by a 9200 in. lb. torque variable speed hydraulic motor with forward and reverse. All bearings can be greased from ground level.
A Muncie or Chelsea Electric Over Air Shift.
A two (2) or three (3) speed, depending on application, rear mounted remote switch allows operator more control over which speed and pressure each particular job requires. As a safety feature, the switch will not operate unless the park brake is set on the vehicle.
