Section III Technical Principles of Operation
1-10 DRIVE OPERATION
The center drive system consists of a motor unit, a drive pulley, the take-up roller, several idlers, and the associated
linkages. As the motor turns, the center drive pulley is rotated by the chain, and causes the belt to move on the conveyor.
The take-up roller, and idlers are used to keep proper tension on the belt, and reduce slippage. Belt tracking can be
controlled by adjustment of tail pulleys and idlers.
1-11 LIFTER
The lifter unit allows one end of the conveyor to be elevated. Cranking the lift handle clockwise will cause the lift
mechanism to move the lift end of the conveyor upwards, cranking counterclockwise rotation will lower the conveyor. This
allows for easy and accurate positioning of the machine. Maximum height is 118". Maximum incline is 30 degrees.
CAUTION:
ENSURE THAT THE LOCKING PINS ARE REMOVED FROM THE CONVEYOR
BEFORE IT IS RAISED. FAILURE TO DO SO MAY CAUSE EQUIPMENT DAMAGE.
1-12 CONTROLS
The start switch, stop switch, and directional selector switch are the only controls the operator need be concerned with
once the machine is properly setup. The start switch will cause the conveyor to begin to move in the direction indicated by
the directional selector switch. Either stop button will cause the belt to immediately cease movement.
