Flexco DRX3000 User manual

PHYSICALLY LOCK OUT AND TAG THE CONVEYOR AT THE POWER
SOURCE BEFORE YOU BEGIN INSTALLATION.
2. Visuallylocatecenterofloadingzone.Determine the
center of the load zone on one side of the structure and
mark (Fig. 2). Measure to a xed point on the structure
and then transfer this dimension to the opposite side
structure.
1. Takeoutthecurrentsystem.Remove existing impact
idlers or bed from area. Loosen or remove skirting
material for extra space. If available, use two Flex-
Lifters™ (before and after the load zone) to lift the belt
out of the way.

Installation Instructions
for DRX3000 Models
FIG.1a
Caution:Components may be heavy. Use safety approved lifting procedures.
BeforeInstallation:Conrm depth of 5" (125mm) clearance below the top of the conveyor
structure for the impact bed to travel while absorbing the load (Fig. 1). Inspect structure;
conrm CEMA rating. TheFlexcoDRX3000DynamicImpactBedisdesignedexclusivelyto
functionwithCEMAErollers. For use with CEMA C or D rollers please call the factory. NOTE:
Installation of an idler is required 1" (25mm) before and 2" (50mm) after a Flexco DRX Dynamic
Impact Bed (Fig. 1a).

3. Placesuspensionrails.Center suspension rails over
center marks and clamp lower impact energy absorber to
the structure. Impact energy absorber linkages must be
positioned to move down and forward in the same direction
as belt travel (Fig. 3).

FIG.4
4. Squaresuspensionrails.Loosen clamps as necessary.
Spread suspension rails until leg of crossbrace ts
inside rails and bolt in place. Center assembly over the
structure. Measure A-B and C-D dimensions and move
until they are equal. Weld crossbraces to suspension
rail. Weld lower impact energy absorber to structure and
remove clamps (Fig. 4).
FIG.5
5. Compresssuspensionrails.Compress suspension rails
with four C-clamps to give an additional 2.5" (63mm) of
clearance for assembly (Fig. 5).
FIG.6
6. Disassemblewingassemblies.Remove the center
mount bolt and the two outer ange bolts. Slide out and
remove the wing assembly on each channel crossbeam
(Fig. 6). (Keep bolts, nuts and washers for use later.)
7. Installcrossbeams.Slide all crossbeams onto the
conveyor structure and set on lower inside ange of
suspension rail. Bolt in place with bolt facing up to
minimize space constraints (Fig. 7). NOTE: Crossbeams
must all be in line before tightening down.

8. Installwingsintothe“serviceposition”.Slide the
wings into the crossbeams to the service position.
The notch in the base of the wing will t over the rail
(Fig. 8). NOTE: Conrm all of the bar mounting tabs
on the wings are pointing towards the tail pulley.

9. Installimpactbars.Place all the impact bars in
place. Position studs between the tabs in the wing
bracket; conrm the chamfer of the impact bar is
positioned at the tail pulley end of the bed. The notch
in the bar support will also t over the wing (Fig. 9).

10.Fastenimpactbars.With all the impact bars
correctly positioned on the wing brackets, install a
at washer, lock washer and nylock nut on each
stud. Tighten nuts to 100 ft-lb torque (Fig. 10).
FIG.10
11. Placewingsintooperatingposition.With all the
impact bars in place, lift and slide in until the outer
mounting holes of the wing bracket align with the
inner mounting holes of the crossbeam. Reinsert
the two mounting bolts and the center retaining bolt
in each wing bracket. Tighten to 100 ft-lb. Remove
C-clamps (Fig. 11).

13.Adjuststationaryarms.Loosen upper bolts on
stationary arms and adjust height to match belt and
chute. Retighten bolts. Finish welding arms in place
onto the structure (Fig 13).
14.Conrmcorrectclearancebetweenchuteandbelt.
Readjust skirt rubber to make a good seal against
impact bed (Fig. 14). Replace all protective guarding
around load zone.

12.Installstationaryarms.Place stationary arms
onto structure and align holes in base with center
of impact energy absorbers. (Chamfer on impact
bars must face tail pulley.) Line up stationary
impact bar with center bars. Clamp in place and
tack weld to structure on both sides (Fig. 12).
