Hopper & leg installation
(see figure ‘Hopper & Leg Installation’)
There are three types of hoppers for your dust collector:
1. a single module wide which spans two portholes
2. a single module wide which spans three portholes
3. a double module wide which spans four portholes
Each of these styles transition to a single outlet opening. All of the leg arrangements
are shown in figure 6, ‘Leg positioning’. The position of the legs, cross bracing and
hoppers for each dust collector size is shown.
1. Stand the hopper(s) up with the disposal end up (hopper outlet).
2. Use drift pins to align the holes in the hopper gussets and legs, and attach the legs
with the bolts, washers and nuts.
Do not tighten hardware at this time!
3. Use drift pins to align the holes in the cross bracing on the rear side of the leg set.
4. Recheck the position of the legs and cross bracing against figures ‘Leg Bolting
Details’ and ‘Standard Leg Packs’ and the drawing.
5. Join hoppers together at the hopper gussets using bolts, washers and nuts.
Do
not tighten hardware at this time!
6. Flip over the now-assembled hopper/leg pack assembly so that it is standing on
its legs (hopper outlet pointing down). This step may require a crane. Another
option is to divide the hopper/leg pack assembly into smaller sections to flip over.
Make sure to join hopper together after flipping over.
7. Lift the assembled collector onto the foundation. Fasten each footplate of the
leg anchor bolts with flat washers, lock washers and nuts.
Do not tighten
hardware at this time!
(Depending on the type of anchor bolts, anchor bolts
can be mounted afterwards).
