View source for Cantilever grizzly

Grizzly fixed at one end only, the discharge end being overhung and free to 
vibrate. This vibration of the bar is caused by the impact of the material. The 
disadvantage of the ordinary bar grizzly is clogging due to the retarding 
effect of the cross rods. This has been overcome in the cantilever grizzly by 
eliminating the tie rods except at the head end, where they are essential. The 
absence of these rods below the point of support also aids in preventing 
clogging because it permits the bars to vibrate in a horizontal plane, which 
keeps the material from wedging.
