TM 5-3895-374-10 Item Procedure 13 Using the hydraulic control valve mounted on the left hand side of the platform, extend the drum feed cylinder pushing the drum into the tank. (One or two drums may be pushed in at one time). NOTE The drum will not go all the way into the tank. Proceed with the next one or two drums and place them in the drum feed system. Extend the hydraulic cylinder and the first two drums will be pushed all the way into the tank and the second one or two will protrude slightly. 14 Continue this process as long as required. 15 At one to two hour intervals, transfer the liquid asphalt from the dedrummer tank to the asphalt tanker by running the asphalt transfer pump mounted on the front of the asphalt tanker. Open the valve to the asphalt tank and select the asphalt pump switch to the ON position. Run the pump for as long a period as required to empty the dedrummer tank. 16 Select OFF on the asphalt pump switch and close the valve to the asphalt tank. 17 The empty drums will exit the doors at the rear of the tank. Note If the drums are not empty of asphalt when they exit the dedrummer tank, they are not hot enough. Correct this by increasing the set point temperature of the hot oil heater (caution: do not exceed 4000) or increase the time that the drums are in the tank. 18 Upon completion of the dedrumming operations, pump all asphalt cement from the dedrummer tank, close the four valves to the hot oil lines connecting the dedrummer and the asphalt tanker. Allow the dedrummer to cool before attempting to remove the last of the empty drums from the tank. 19 On the hydraulic power pack, select the breaker to the OFF position. 2-21 Operating Malfunctions The following are some of the malfunctions which may be encountered during the, operation of the plant.
