(Overload Safety Device Installed on Screw Conveyor
Shaft)
C-30HD — SERVICE INFORMATION: TORQUE LIMITER (MODEL C30-SP ONLY)
While pumping, if the Screw Conveyor at the bottom of the
hopper is fouled or stopped because of rocks, the Torque Limit
slips to prevent chain breakage.
If this condition exists, stop the pump and rotate the large
pulley by hand in reverse direction to free the Screw.
If the rock blockage is severe, it may be necessary to
disconnect the Drive Chain and turn the Screw Conveyor Shaft
using a wrench at the end nearest to the Jolter Cam.
Reconnect the chain and resume pumping.
