The BestReach Rigid Roller Conveyor is designed to be virtually maintenance free. We do
recommend that you regularly inspect the unit to ensure proper operation of mechanical
and safety systems.
Daily:
zMake sure all guards and caution decals are in place and secure.
zKeep the conveyor clean and free of debris, dirt and grease accumulation.
zTest all Emergency Stop switches and Bumper Stop Switches to verify proper
operation.
zEnsure photoeyes are clean and unobstructed.
zClean floor track of debris or other objects that may interfere with electrical cable
carrier.
Weekly:
zInspect roller drive belts for wear. Replace excessively worn belts.
zVerify the Extend and Retract Limit Switches stop the conveyor at both ends of
travel.
zCheck drive chain tension.

Maintenance Schedule

Maintenance Schedule, Motors
DC Motor Brush Maintenance
All motors used to power the conveying surfaces of the Best Reach Rigid Roller and Best
Flex conveyors are DC permanent magnet motors. These motors have a pair of
serviceable brushes that wear with use. Brush life is affected by the speed of the motor,
the loads being conveyed, the number of start-stop cycles and other factors. Therefore,
brush life will vary from application to application.
To ensure long motor life, brush inspection should be included in the normal maintenance
schedule of the conveyor. Brushes should be periodically removed, visually inspected and
measured.
The brushes are accessed by removing the two caps on the end of the motor opposite of
the gearbox (see photo 1 on page 8). With the cap removed, the brush may be removed
from its holder by pulling on the spring. Visually inspect the brushes for chips or grooves.
The shunt wire should not be frayed or broken. The brush should be replaced if it
measures 0.125 inches or less as shown in Figure 1. Possible armature damage could
result from running the brushes beyond this wear point.
When being installed, the brush should slide freely into the holder. The brass contact
connected to the top of the spring should be installed so its tabs are aligned with the motor
shaft (photo 2). One tab should be facing the rear of the motor and the other tab toward
the front. The tabs should go easily into the brush holder. Do not over tighten the plastic
cap that holds the brush in place.

Unloading Units
1) Upon arrival all conveyors will be secured with wood blocks mounted to the trailer floor.
All wood blocks must be removed prior to moving the conveyors.
2) Warning: Conveyors must not be picked up utilizing forks on the rear of the unit. Failure
to adhere to this warning may cause damage to the main electrical panel on the back of
the unit, or the electrical connections coming into this panel. This damage will not be
covered under warranty.
3) To unload, the unit may be either manually pushed from the front of the conveyor, or by
utilizing a lifting strap placed around the rear frame of the conveyor and attached to a
forklift. If using the strap method, make sure that the strap does not come in contact
with any electrical wiring under the conveyor.
4) The steering actuator on the front axle of the conveyor has been disconnected for ease
of movement. When using either unloading method, someone must manually steer the
front of the unit to prevent damage to the front control panel.
Installation
Installation should only be performed by Best Conveyor Installers or qualified personnel, and
must be completed in accordance with all applicable codes and regulations.
1) Locate and mark the center of the spur. Chalk a line from the dock leveler back
approximately 50 feet. Measure 2 inches off each side of the centerline, this will give
you the inside dimension on track placement location, 5 inches off the center will give
you the outside line placement. NOTE: It might be helpful to cut 2, 4-inch blocks.
Center these blocks on your chalk line at the front and back of each piece of track, so
that you have 2 inches on either side of the line. Proceed to assemble the track as
instructed below.
2) Mark location for the front of floor track as shown on supplied application specific
drawing (if you do not have this drawing, please contact the factory.)
3) Locate and position the individual pieces of floor track as shown on drawing A.
4) Assemble the rear sections of floor track as shown in drawing B.
5) Position and anchor floor track starting with the front and aligning the inside edge with
the 2-inch or 5 inch measure out, or utilize your cut blocks for this placement.
6) Pull 2 lengths of SO cable (50’ 18/10 and 60’ 14/4) through flexible wire carrier.
7) Attach the included connection brackets to each end of the flexible wire carrier. These
parts and hardware are shown in Drawing C on page 14.
8) Feed both lengths of SO cable under rear wire cover (C channel illustrated in Drawing B
on page 13 Item # 7) exposing approximately 10” at the rear of the floor track. Attach
the flexible carrier to the wire cover (C channel).
9) Install 2 cord grips (not included) in 7/8 holes of 8x6x5 junction box that is provided.
Installation

Installation (cont.)
10) Feed Approximately 10” of the SO cables thorough the cord grips and install junction
box on floor toward the rear of the floor track. Box should be held off the ground
utilizing Uni-strut or some other suitable material. This material is not included and will
need to be provided by the installer.
11) Pull slack cable through the opposite end of the flexible wire carrier.
12) Lay flexible wire carrier flat in the floor track.
13) If the conveyor is going to be installed from the dock end of the floor track, the stop
bar must be removed from the conveyor. If the conveyor is to be installed from the
rear of the floor track, the stop bar and the UHMW guide roller must be removed from
the conveyor.
14) Roll the conveyor into position on guide track and re-install stop bar and guide roller.
15) Connect Flexible wire carrier to the underside of the conveyor.
16) Route and secure 14/4 SO cable into main electrical enclosure box and terminate as
shown in Diagram B on page 21, connecting to the L1, L2, L3 and ground contacts.
17) Route and secure 18/10 SO cable into 12” x 12” box, and terminate as shown in
Diagram A on page 20.
18) Terminate wires from both SO cables in the floor junction box as shown on page 18.
Supply line voltage, as shown on the nameplate to 14/4 SO cable junction in floor
track junction box. This line voltage must be connected to a separate fused
disconnect rated at no more than 15 amps. This connection is shown as an option on
page 19, or may be provided by the installer. Conduit, straps, wire, hardware, etc. that
are used to connect the floor track box to the disconnect must be provide by the
installer. All wires that are pulled must be labeled to correspond to those in the floor
track box. The remaining 18/10 SO cable wires are interlock connections and should
be connected as shown in the optional disconnect stand drawing on page 19. Connect
applicable interlock wires to 18/10 SO cable in 8 x 6 x 4 junction box.
19) Remove chain guard and install and tension the chain.
20) Install the Herringbone transition to the end of the fixed feeder conveyor.
21) If purchased, install the full-line read assembly to the rear of the Transition plate as
shown on page 71-72. The wheel bracket should be attached to the plate and the
wheel should ride on the conveyor bed. When assembling the wheel bracket, be sure
not to over tighten this assembly. The wheel should roll freely within the bracket.
22) Electrical connections to the proximity switch on the full-line read must be made as
shown on page 74. The wire from the switch must be secured to the transition using
standard wire ties. Be sure to leave a little slack in this wire, so that it is not pulled too
tight. The box for this connection is not included and must be provided by the Installer.
23) The power and signal wire must then be routed back to the disconnect stand and
secured to their corresponding numbers on the terminal strip. These wires must be
ran in some type of electrical conduit, which is normally attached to the fixed feeder
conveyor. Conduit, straps, wires etc. are not included and must be provided by the
installer. These wires also must be numbered to correspond with the listed numbers
on the drawing on page 19.
