Connect the two heat transfer lines and the asphalt transfer line from the asphalt tanker to the dedrummer.
See section 2-5.
Open the valves on either side of these lines allowing the heat transfer fluid to circulate through the
dedrummer. The asphalt transfer line will be open and will permit pumping of asphalt cement from the
dedrummer to the asphalt tanker.
Raise jib and install electric hoist on to the trolley. See section 2-5.
Position the hydraulic power pack beside the goose neck of the trailer on the left hand side and connect the
hoses to the control valve for the drum feed cylinder.
Plug the power cable for the electric hoist and the power cable for the hydraulic power pack into the control
Unlatch the two doors at the discharge (rear) end of the dedrummer tank.
The hot oil heater on the asphalt tanker must be running. Use a temperature set point of 3500 on
the heat transfer controller mounted on the hot oil heater. This higher temperature will maintain
the heat transfer fluid at a higher temperature and will compensate for the heat required to raise
the temperature of the asphalt cement In the drums. Allow the temperature of the dedrummer to
rise to at least 250° prior to feeding drums into the unit This temperature Is checked on the dial
thermometer mounted on the front wall of the dedrummer tank.
Use the chain hoist and the drum rotator to lift the drums up to the platform or use a forklift to raise the drums
to platform height.
Remove the lid from the drum.
Item number 8 may be performed prior to lifting to the platform.
Using the hoist, lift the drum six to eight inches and with the drum rotator turn the drum upside down.
Using the jib and the chain hoist, position and lower the drum into the drum feed system.
Open the doors to the dedrummer.
Start the hydraulic power pack motor by turning the breaker switch mounted on the pack to the ON position.
