conveyor operation
“LEFT TRAM” “RIGHT TRAM” Primary valve bank
The primary valve bank (Fig. 13) is used to manually operate the machine when radio remote operation is not possible. The valve section handles are stored in a storage tube beside the valve bank. To manually operate the machine, the “MAN/OFF/AUTO” switch must be in the “MAN” position.
The valve bank consists of the following hydraulic controls:
NOTICE! Once a hydraulic control valve handles is released by the operator, any lever except “POWER FILL/SECONDARY” will automatically return to the centered (neutral) position.
The first two sections on the operator’s left are conveyor forward and reverse. The two sections can be used independently or together to control conveyor direction and speed. To run the conveyor in the forward direction (towards the discharge end), push either valve handle up. If the conveyor is sluggish, use both valve sections. To run the conveyor in reverse (towards the receiving hopper), push either valve handle down. If the conveyor is sluggish, use both valve sections.
Note: The two conveyor valve sections are tied to a common circuit. Using both valve sections will increase flow to the conveyor motors, increasing speed.
The third section from the operator’s left controls the left tram functions.
The fourth section from the operator’s left controls the right side tram functions.
WARNING! When tramming the machine from the operator’s station, the operator should stand beside the machine facing the conveyor with the tram control levers at arms length. Care should be taken to ensure that the operator’s feet do not get under the crawler tracks while the machine is moving.
The tram/steering control levers are used for tramming and positioning the machine. To tram the machine forward in a straight direction (towards the receiving end), push both tram control levers forward and to tram the machine in a straight direction in reverse (towards the discharge end), pull back on both tram control levers. To steer left in the direction of the receiving end, push the right tram control lever towards the machine while the left tram control lever is in the neutral position or for tighter turns, pull the left tram control lever towards the operator. To steer right in the direction of the receiving end, push the left tram control lever towards the machine while the right tram control lever is in the neutral position or for tighter turns, pull the right tram control lever towards the operator.
