INSTALLATION
• Conveyor Set-Up
1. Mark a chalk line on floor to locate center of the conveyor.
2. Align spur plate to side of adjacent conveyor, while aligning center line to
chalkline or centerline of feeding/receiving conveyor.
3. Check to see that conveyor is level across width and length of unit. Adjust
supports and ceiling hangers as necessary.
4. Install electrical controls and wire motor.
• Electrical Equipment
CONTROLS
Electrical Code: All motor controls and wiring shall conform to the National
Electrical Code (Article 670 or other applicable articles) as published by
the National Fire Protection Association and as approved by the American
Standards Institute, Inc.
CONTROL STATIONS
A) Control stations should be so arranged and located that the operation of
the equipment is visible from them, and shall be clearly marked or labeled to
indicate the function controlled.
B) A conveyor which would cause injury when started shall not be started
until employees in the area are alerted by a signal or by a designated person
that the conveyor is about to start.
When a conveyor would cause injury when started and is automatically
controlled or must be controlled from a remote location, an audible device
shall be provided which can be clearly heard at all points along the conveyor
where personnel may be present. The warning device shall be actuated by
the controller device starting the conveyor and shall continue for a required
period of time before the conveyor starts. A flashing light or similar visual
warning may be used in conjunction with or in place of the audible device if
more effective in particular circumstances.
Where system function would be seriously hindered or adversely affected
by the required time delay or where the intent of the warning may be misin-
terpreted (i.e., a work area with many different conveyors and allied devices),
clear, concise, and legible warning shall be provided. The warning shall
indicate that conveyors and allied equipment may be started at any time, that
danger exists, and that personnel must keep clear. The warnings shall be
provided along the conveyor at areas not guarded by position or location.
C) Remotely and automatically controlled conveyors, and conveyors where
operator stations are not manned or are beyond voice and visual contact from
drive areas, loading areas, transfer points, and other potentially hazardous
locations on the conveyor path not guarded by location, position, or guards,
shall be furnished with emergency stop buttons, pull cords, limit switches, or
similar emergency stop devices.
All such emergency stop devices shall be easily identifiable in the imme-
diate vicinity of such locations unless guarded by location, position, or guards.
Where the design, function, and operation of such conveyor clearly is not
hazardous to personnel, an emergency stop device is not required.
The emergency stop device shall act directly on the control of the con-
veyor concerned and shall not depend on the stopping of any other equip-
ment. The emergency stop devices shall be installed so that they cannot be
overridden from other locations.
D) Inactive and unused actuators, controllers, and wiring should be removed
from control stations and panel boards, together with obsolete diagrams, indi-
cators, control labels, and other material which serve to confuse the opera-
tor.
SAFETY DEVICES
A) All safety devices, including wiring of electrical safety devices, shall be
arranged to operate in a “Fail-Safe” manner, that is, if power failure or failure
of the device itself would occur, a hazardous condition must not result.
B) Emergency Stops and Restarts. Conveyor controls shall be so arranged
that, in case of emergency stop, manual reset or start at the location where
the emergency stop was initiated, shall be required of the conveyor(s) and
associated equipment to resume operation.
C) Before restarting a conveyor which has been stopped because of an
emergency, an inspection of the conveyor shall be made and the cause of
the stoppage determined. The starting device shall be locked out before any
attempt is made to remove the cause of stoppage, unless operation is neces-
sary to determine the cause or to safely remove the stoppage.
Refer to ANSI Z244.1-1982, American National Standard for Personnel
Protection – Lockout/Tagout of Energy Sources – Minimum Safety
Requirements and OSHA Standard Number 29 CFR 1910.147 “The Control
of Hazardous Energy (Lockout/Tagout).”
WARNING! Electrical controls shall be installed and wired by a qualified
electrician. Wiring information for the motor and controls are furnished by
the equipment manufacturer.
• Support Installation
1. Attach supports to both ends.
2. Adjust elevation to required height.
• Ceiling Hanger Installation
If conveyors are to be used in an overhead application, ceiling hangers may
have been supplied in place of floor supports.
Figure 4A shows how a ceiling hanger mounts to a conveyor section.
Ceiling hangers should be mounted at section joints.

NOTE: When installing ceiling hanger rods in an existing building, all
methods of attachment must comply with local building codes.
CAUTION! Snubbing the belt too much can cause the conveyor to stall.
• Pressure Adjustment
The spurs have positive drive snub sheaves that hold the drive V-Belt in con-
tact with its tread rollers. Adjustments are made by moving the snub sheaves
up or down in the slotted conveyor channel. When making adjustments, apply
only enough force to move the heaviest item to be conveyed. To make this
adjustment, follow the steps listed below.
1. Use a wrench to slightly loosen the snub sheave nut on the outside of the
frame (Do NOT loosen from the inside of the frame).
2. Lightly tap the nut with a hammer and punch. Tap the nut upward to
increase drive pressure or downward to decrease drive pressure. Make
adjustments in small increments.
3. Once the adjustments have been made, retighten the nuts.
NOTE: Use caution when making adjustments. Apply only enough pressure
to move the heaviest item. Raising the sheaves too high can put an excessive
load on the drive and result in premature belt failure and/or roller bearing
failure. Lowering the sheaves too low can cause the belt to fall out of the
sheave, resulting in damage to the belt.
