BODY INSULATION

The asphalt aggregate hopper and road oil tank are fully insulated with 2” industrial, high temperature 12R factor insulation encased in a double steel jacket.

CAPACITY

The asphalt aggregate hopper holds 4 cubic yards level full or 6 tons maximum load` .

HEATING SYSTEMS

The body shall have a dry radiant heat chamber heated by 2 each 67,000 BTU retort tube propane burners with vertical exhaust stacks. The exhaust stack dampeners are electronically actuated to close when burners are off to reduce heat loss. The burners are thermostat controlled and regulated at 10 PSI. The ignition system is 12 volt DC with electronic igniter. Gas burner has a safety shut-off on loss of �lame or excessive temperature. Automatic safety shut-off when diesel pump is operating. Burner ignites on 10 oz. pressure, operates at 10 PSI, on high burn regulated by the same thermostat as the electric heater. Thermostats will be 0/300° F. solid state. Systems using Heat Transfer Oil are not acceptable.

ELECTRONIC CONTROLS

All electronic controls will be solid state shock resistant. Thermostat for tack oil tank is 50/200° F. Thermostat for asphalt aggregate hopper is 0/300° F. Digital with temperature read out. Thermostat for the asphalt hopper has built in high limit safety shut down switch. Same thermostat controls the 12 volt LP Gas �ired system and the 220 volt electric heating system.

EMULSION OIL TANK CAPACITY AND HEATING SYSTEM

The tank, built onto the main body, has a capacity of 60 gallons and a double steel jacket with 2” insulation. Tank is heated by 2 ea 110V electric heater with Ampeak 2000 W 12 Volt Converter. With a 220 volt overnight electric heater. Both heaters are thermostat controlled.

The emulsion pump and all lines are in an insulated heated area. The tank has 220 volt thermostat controlled NEMA explosion proof dry well electric heater. Tank has an 8” �ill spout and a 2” gate valve on tank drain. For ease of maintenance or change out of heater, tank does not have to be drained.

ELECTRIC HEATING SYSTEM

The asphalt aggregate hopper and liquid asphalt oil tank is heated by a 220 volt, 62 kw OSHA required NEMA explosion proof dry well electric 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 up to 300° F. during non-working hours. With a 110V electric heater during working hours.

HYDRAULIC CONTROL VALVE

Five spool, two-way, variable �low 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. Electric 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.

HYDRAULIC OPERATED STEEL TOP DOORS

Two (2) hydraulically operated bi-fold steel top doors with hex brake for rigidity. Doors are insulated with 2” of high temperature insulation in a double steel jacket. The doors have rain seal caps and �lex plates to keep asphalt out of door hinges. Each door shall have a 1 ½” bore with 13” stroke hydraulic cylinder with bypass and �low control valves. The controls for doors are at the rear of the unit.

HYRAULIC REAR LIFT PLATFORM FOR COMPACTOR OR ROLLER

Equipped with a hydraulically operated lift platform for loading or unloading compactor or roller. The platform has a Safety latch in the up position, an in cab “platform down” indicator light with compactor holding down brackets. All controls for platform are at the rear of the unit.

ASPHALT DISPENSING SYSTEM, SCREW CONVEYOR TYPE

9’ long by 10” diameter progressive screw conveyor has hard surfaced �lights welded continuously on 2” scheduled 80 pipe and is ball bearing mounted. Conveyor is driven by a 13,000 in.lb. torque variable speed hydraulic motor with forward and reverse. Shall have a delivery chute with 120° of pivot. All bearings can be greased through a feeder line mounted outside the unit from ground level.

ASPHALT AGITATOR

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 13,000 in.lb. torque variable speed hydraulic motor with forward and reverse. All bearings can be greased through a feeder line mounted outside the unit from ground level.

LP GAS BOTTLE

100 Lb. 25 Gallon LP gas bottle, complete with quick couplers and 10 PSI regulator.

HAND TORCH

For drying off repair site and cleaning hand tools, the unit has a 200,000 BTU propane hand torch with shut-off valve and 10’ of hose with hose rack. Hand torch has mounting bracket for transport.

TEMPERATURE GAUGES

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 emulsion pump and all oil lines are in an insulated heated area. 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. With auto retractable hose reel.
