1.
Determine proper mounting location. Assure a
mounting angle greater than 20°, unless 'SP' type.
2.
Skip weld reinforcing bars to hopper. Do not weld
corners. NAVCO can recommend weld specifications if
required.
3.
Skip weld both channel legs to reinforcing bars. Do
not weld corners. NAVCO can recommend weld

Vibration Technology for Processing Bulk Materials
Mounting Considerations
Reinforcement plates are always recommended. The
reinforcement plate should match bin wall thickness up to 1/2".
A reinforcement plate of 1/2" thickness should be used on bin
walls exceeding 1/2" thickness. Refer to NAVCO installation
drawings for reinforcement plate dimensions.
If the hopper slope angle is greater than 70° from the horizontal,
a piston return spring is recommended to ensure positive
starting action (BH 1.62 through BH 6.00 only).
Vibrator(s) should be located according to NAVCO bin map or
installation drawing.
