Hopper Vibrator
This device is an electric motor that has eccentric
weights attached to a shaft at each end. When the mo-
tor spins, the weights shake the unit, and whatever is
attached to it (the hopper grate or hopper, in our case).
The purpose of this device is to assist low slump con-
crete in falling through the grate, and into the concrete
cylinders. If your use of this machine includes pumping
of low slump concrete, you will nd this option invalu-
able.
Auto Greaser
For information on setting or adjusting the autogreas-
er, reference “SKF Piston Pump Units with Reservoir”
