4. 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 flex plates to keep asphalt out of door hinges. Each door shall have a 1 ½” bore with 13” stroke hydraulic cylinder with bypass and flow control valves. The controls for doors are at the rear of the unit.
The asphalt aggregate hopper holds 3 or 4.25 cubic yards level full or 4 or 6 tons maximum load.
6. HEATING SYSTEMS
The body shall have a dry radiant heat chamber heated by 2 each 67,000 BTU LP Gas or 1 each 100,000 BTU Diesel Fired retort tube burners with vertical exhaust stacks. Exhaust stacks have an automatic electronic dampener that opens when burners are fired and close when burners shut off to prevent heat loss. The burners are thermostat controlled and regulated at 10 PSI. The ignition system is 12 volt DC with electronic ignitor. Gas burner has a safety shut-off on loss of flame or excessive temperature. Automatic safety shut-off when diesel pump is operating. Burner has two stages, ignites on 10 oz. pressure, and operates at 10 PSI, on high burn regulated by the same thermostat as the electric heater. Thermostats will be 0/300° F. solid state.
7. 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. 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.
8. LIQUID ASPHALT EMULSION TANK CAPACITY
For capacity, refer to list of models available. The tank has a double steel jacket with 2” of R12 insulation. The tank is heated with 110 volt thermostat controlled dry well NEMA explosion proof electric heater and a hot well for storing spray wand in cold weather. The liquid asphalt pump and all lines are in an insulated, heated area.
9. ELECTRIC HEATING SYSTEM
The asphalt aggregate hopper and liquid asphalt oil tank is heated by a 220 volt, 62kw 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 from 0 to 300° F during non-working hours.
One (1) – 100 LB (25 gallon) removable propane bottle complete with 10 PSI regulator valve and dual bottle lockable storage rack.
11. TEMPERATURE GAUGES
The unit has two 3” dial type, stainless steel temperature gauges that constantly monitor the temperature of the asphalt hopper and road oil tank.
12. HAND TORCH
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 with hose rack. Hand torch has mounting bracket for transport.
13. LIQUID ASPHALT OIL PUMP
A hydraulically driven, 1½” 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.
14. 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.
15. SPRAY WAND
Diesel Fuel Spray Wand with 10 ft. hose.
16. HYDRAULIC OIL RESERVOIR
25 gallon capacity with sight and temperature gauge, ventilated fill cap, 150 micron sump strainer and a 10 micron return filler.
17. HYDRAULIC HOSE AND FITTINGS
All high pressure hoses and crimped fittings have a minimum of 9600 PSI burst pressure.
18. 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. The valve has an internal or external safety design that will 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. Valve shall have Quick Couplers to run off Truck Hydraulic System.
19. SCREW CONVEYOR
10’ long by 6” diameter progressive screw conveyor has hard surfaced flights welded continuously on 2” scheduled 80 pipe and is ball bearing mounted. A 3/16” replaceable insert liner is skip welded full length of main asphalt aggregate hopper beneath screw conveyor. 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.
20. SECONDARY AUGER MOTOR
A secondary, hydraulic, 13,000 in.lb. Torque, variable speed booster motor installed at rear of auger to assist in dispensing bad or stiff asphalt mix. This also eliminates shearing coupler keys and bolts in the auger shaft.
21. 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 ground level.
22. DIESEL FUEL / RELEASING AGENT STORAGE TANK
A 10 gallon capacity tank, equipped with a 1.6 gpm @ 60 psi 12 volt DC pump and a hand sprayer or cleaning tools and unit. There shall be a connector valve for flushing road oil pump and lines and a 1” drain.
