Drive, push floor screw conveyor, standard

Part no. 7387 925

Standard version for push floor screw conveyor with pulling drive and
discharge into a drop section. The system is driven via a spur geared
motor and chain in a dust-proof chain guard. 

Standard delivery:

■ Drive unit with spur geared motor 400 V and chain drive
■ Light barrier across the entire open area for monitoring the fill level

(overfill protection)

■ Discharge with inspection cover, safety limit switch and downpipe/

adaptor for the following conveyor device (not required in pushing
version)
