Operation
During the loading process the following actions will take place:
n
Opening of bottom valve
n Closing of bottom valve
To open / close the bottom valves operate one of the operating devices E at either side of the tank.
See drawing on page 4
When opening the operating device
E remove - if necessary - the custom‘s lead seal from the bolt M.
. To open the operating device E push the bolt M upwards and then turn it by 90° to one side.
You can now swing down the lid.
2. Make sure that the pump lever of the hydraulic pump F is completely extended towards the front.
3. Connect the rail hook C (e. g. rail hook VZ 0) to the tension rope and engage it in the rail.
The ball valve of the control unit X of the bottom vale will close and the hydraulic system is ready for operation.
4. The up-strokes and down-strokes of the lever of the hydraulic hand pump F in the operating device E
build up pressure in the hydraulic system, causing the two bottom valves to open simultaneously.
After approx. six strokes of the pump lever both bottom valves will be completely open. Check position
of bottom valves: The opening position of the bottom valves is indicated by the two completely extended
indicating pistons O of the indicating cylinders H (lift of indicating pistons approx. 46 mm).
5. Open the lateral shut-off valves A to start the loading/unloading process.
6. The pump lever of the hydraulic pump F is no longer required and must be returned to its original position.
Attention
If only one operating device for the loading system was opened, the lid of the other operating device
cannot be opened when the bottom valves are open.
Close bottom valves immediately after loading or unloading the tank.
See drawing on page 4
7. To close the bottom valves disengage the the rail hook
C from the rail. This will loosen the tension rope.
The ball valve of the control unit X opens the hydraulic system and both rapid-action bottom valves will be
closed instantaneously. Be sure that both bottom valves are closed by checking the indicating pistons O
of the indicating cylinders H. Both indicating pistons must be retracted.
8. Then close and latch the operating device E.
9. To finish the loading/unloading process close the shut-off valves A and attach the sealing plugs to the
shut-off valves.
Attention
Note: If the lid cannot be closed, one or both bottom valves are still open!
The inside of the lid of the operating device features a bracket. This bracket prevents the closing
of the lid when one or both bottom valves are open. The lid can only be closed when the indicating
pistons are retracted. The cause of this malfunction must be ascertained and eliminated!
If only one operating device for the loading system was opened, the lid of the other operating device
cannot be opened when the bottom valves are open.
