sleeve clamps for tightness. Suspension arm bolts
are Grade 5 and must be torqued to 466 foot
pounds; vibrator mounting bolts as follows:
3 / 8” BOLT GRADE 5 25 FOOT POUNDS
1 / 2” BOLT GRADE 5 60 FOOT POUNDS
5 / 8” BOLT GRADE 5 120 FOOT POUNDS
3 / 4” BOLT GRADE 8 296 FOOT POUNDS
7 / 8” BOLT GRADE 8 473 FOOT POUNDS
1” BOLT GRADE 8 714 FOOT POUNDS
Metalfab 10 foot and 12 foot diameter Bin Activators
and special units are shipped unassembled, in some
cases the mounting flange is split in half for shipping
purposes.
When installing units not completely assembled, the
correct procedure is to completely assemble the unit
at grade with the following procedure:
A. Stand or support the Bin Activator in a level
position (discharge outlet facing down).
B. If applicable, join the two (2) halves of the upper
mounting flange and tighten securely or weld.
C. If not already in position, place the flexible
sleeve and two (2) complete sleeve clamps on
the Bin Activator ***** leave clamps loose.
D. Position the assembled mounting flange on the
Bin Activator.
E. Install all suspension arms, insert high strength
bolts in upper and lower holes and snug up
each elastic stop nut and bolt.
After all nut bolts are installed snug, tighten to
the correct torque specifications.
F. Check placement of the flexible sleeve to
mounting flange and Bin Activator. A sealant
material such as Silastic or Permatex may be
used between the sleeve and metal surfaces.
G. Position the upper and lower sleeve clamps
close to the beaded edge of the flexible sleeve.
After seating and adjusting clamps, tighten both
securely.
Note: When tightening the clamps, be sure to
support the far side tube with vise grip
pliers when turning nut. Failure to do so
may cause a twisting action on
strapping, which may lead to damage of
clamp.
Run the unit as noted previously and tighten bolts as
required, including sleeve clamps.
VIBRATOR INSTALLATION
This unit imparts vibration to the Bin Activator. It
must be securely bolted to the unit (torque mounting
bolts according to previous instructions), and all
bolts must be retightened after the first ten minutes
of operation and again during the second day of
operation. All nuts and bolts, especially vibrator
mounting bolts, should be retightened every three
(3) months or more frequently depending on the
amount of usage.
Because the Bin Activator and the motor vibrate, the
electrical connections must be made with flexible
lead.
* * Braided neoprene covered cable is
recommended.
Refer to wiring diagram in motor conduit box for
wiring instructions.
VIBRATOR FORCE ADJUSTMENT
The centrifugal force setting of the vibrator is set at
the factory for the minimum force level that will
produce flow of product. If flow is not instantaneous
or continuous, it may be necessary to increase the
centrifugal force. To do so, the following procedure
should be followed:
