packing list. Inspect all equipment for damage.
Claims for damaged equipment must be made
against the carrier immediately.
All units have an identification tag on them.
Important information on the tag includes model
description, item number, and tag number. The tag
number matches the tag number on the layout
drawing, if applicable.
SITE PREPARATION
1. Establish building baselines from the layout
drawings.
2. Lay out centerline and end points of each
unit using the building baselines.
3. Check the installation path for interferences.
FLOOR SUPPORT INFORMATION
All supports are intended to be used at a conveyor
splice or the end of a unit. If a splice cannot
be supported contact your MHS Conveyor
distributor for other options. Support CRUZbelt at
each end and at every splice as shown below.
Leg elevations are shown on the elevation drawings.
Leg elevation can also be set by subtracting 6-3/8”
from the desired top of belt elevation.

ANCHORING CEILING HANGERS
Open building steel:
The following references are from the American
Institute for Steel Construction manual (AISC).
•Welding of auxiliary
steel (stringers or
headers) to building steel is prohibited.
•Drilling and bolting to building steel is not
recommended and will be done only with the
customer’s written permission.
•Clamping of stringers or headers to building
trusses will normally be done only at panel
points. Specific customer permission and
load calculations by a qualified engineer are
necessary to clamp between panel points.
•Headers when used for short spans, such as
between roof purlins, will be securely
clamped to building steel. Stringers when
used between headers may be welded or
bolted to the headers directly or with suitable
angle clips.
Concrete ceilings:
•Anchor by drilling into concrete ceiling and
inserting suitable bolt anchors. Follow bolt
manufacturer’s recommendations for hole
diameter and depth.
•Anchor each hanger with four bolts (two per
upright) minimum ½” diameter.
•Heavier loads like drives or areas of
vibration require 5/8” diameter through bolts
with backup plates or multiple anchor bolts.
Wood joists/beams:
•Hangers may be attached directly to the
joists providing the load rating of the building
will permit. Attach each hanger to the
vertical side of the joist in two places, one
above the other. Drill through the joist in the
upper position and secure with a ½”
diameter through bolt with backup plate or
heavy washer. A ½” diameter lag bolt may
be used in the lower position.
•When a header is required to support the
load, it must bridge across two or more
joists. Attach as described above. Hanger
uprights may then be secured to the header.
Concrete or masonry walls:
•Support equipment by drilling into the wall
and inserting suitable bolt anchors.
•Use a ½” diameter through bolt with backing
plate should the load or wall conditions
warrant.
WARNING
Consult a structural engineer to determine which
anchoring method will support your load.

10. Tension belt by rolling a football bracket
away from the motor. A standard 3/8” drive
ratchet will provide correct belt tension with
ease. Do not over tension the belt by using
a “cheater bar” on the ratchet. Belt should
be just tight enough to drive the product.
11. Replace quick-release pins into both football
brackets. One bracket may need to be
aligned slightly to insert the pin. Replace
drive shrouds.
CAUTION
Do not run the conveyor without replacing
both quick release pins.

ELECTRICAL
WARNING
All electrical controls must be installed, wired, and
connected by a licensed electrician.
All motor controls and wiring must conform to
the National Electrical Code as published by the
National Fire Protection Association and
approved by the American National Standards
Institute, Inc. In addition, since specific
electrical codes vary from one area to another,
be sure to check with the proper authorities
before starting the electrical wiring.
The voltage of the motor will be stamped on the
name plate. This voltage must match available
voltage. Consult the wiring diagram on the motor for
proper connections. If the motor on a single
direction conveyor runs the wrong direction, the
leads must be switched to reverse rotation.
WARNING
Motor must be connected to the voltage
listed on the name plate.
Consult the wiring diagram of the inside cover of the
starter and pushbutton for the proper electrical
connections.
Three phase drives require transformers to reduce
the pushbutton and control circuit to 115 volts. If
primary voltage is changed, the transformer must be
changed according to the wiring diagram found on
the transformer.
NOTE
All controls equipment is covered by the original
manufacturer’s warranty.
NEMA enclosure ratings are as follows:
•NEMA 1- Indoor use, provides protection
against contact with internal components.
Suitable for use in warehouse and
distribution environments.
•Gasketed NEMA 1- Same use as NEMA 1,
but with additional protection against dirt and
dust.
•NEMA 3- Outdoor use, designed to keep out
rain and dust.
•NEMA 4- Indoor and outdoor use, designed
to keep out rain and dust.
•NEMA 12- Indoor use, provides protection
against dust, dirt, oil seepage, and dripping
of non-corrosive liquids. Suitable for use in
industrial environments.
•NEMA 13- Indoor use, provides protection
against dust, dirt, sprayed oil and non-
corrosive liquids.
CONTROLS – SAFETY GUIDELINES
The following are basic conveyor control safety
guidelines for common controls equipment.
WARNING
All safety devices, including wiring of electrical safety
devices, shall be arranged to operate in a “fail safe”
manner. If power failure or failure of the device
occurs a hazardous condition must not result.
START-UP WARNING HORN:
Ideally, all conveyors should be within sight of the
conveyor start button. This allows the operator to
verify no one will be in danger when the conveyor
starts.
An audible warning device is required if all conveyor
cannot be seen from the start button location. It
could be a horn, buzzer, or bell unique to that
conveyor for that location. It must be loud enough to
be head at any point of the conveyor being started.
It should sound for five seconds after the start button
is pushed, prior to the conveyor starting. Any
auxiliary equipment such as vertical lifts, turntables,
etc. must be included in the warning circuitry.
All conveyors that start and stop automatically
should be marked with the appropriate labels.
Adding a warning horn to conveyors that start
unexpectedly is recommended.
START PUSHBUTTONS:
Start pushbuttons should be the flush type or
guarded to prevent accidental activation. They
should be provided with a legend plate defining
which conveyors will be started.
STOP PUSHBUTTONS:
Stop pushbuttons should be the extended type so
that any contact will result in activation. They should
have a legend plate defining which conveyors will be
stopped.

CRUZbelt
13
E0032544Rev090710
OPERATOR CONTROLS:
Additional operator controls should be designed into
the system with the same guidelines that go into
start and stop pushbuttons. Devices which are
repeated on multiple control stations, such as
emergency stops, should be located at the same
relative location on each station. All operator
controls shall be clearly marked or labeled to
indicate the function controlled.
EMERGENCY STOPS:
All locations where an operator must work directly at
the conveyor should be protected by an emergency
stop. Operators should not have to leave their
position to actuate the emergency stop.
Conveyor in areas of high pedestrian traffic should
also be protected by emergency stop devices.
Emergency stops should be located throughout a
system. Their location will depend on likely
observation points and areas with special devices or
interfaces between equipment.
Emergency stops can be a pushbutton or cable
operated switch. The pushbutton should be
mushroom-style and red. The pushbutton must
require resetting after actuation. Cable operated
switches should trip by pulling the cable and require
resetting at the switch.
An emergency stop should normally stop all
conveyors in the system. Very large systems may
involve dividing the system into zones of control.
Actuating an emergency stop must drop out the start
circuit and require restarting the system using the
start pushbutton.
WARNING
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 correct the
cause of the stoppage.
CONTROLS LOGIC:
Solid state controls logic devices, such as
programmable controllers, are used extensively for
conveyor control. They are very reliable, but a
hardware failure or software bug could cause an
output to malfunction. For this reason, start circuits,
warning horn circuits, and emergency stops should
usually be configured using conventional relay logic.
SAFETY SWITCHES:
All conveyor control cabinets and motors should be
provided with safety (or disconnect) switches.
These switches must have provisions for padlocking.
As required for maintenance, equipment should be
locked in the OFF position.
SPECIAL DEVICES:
Special devices and equipment such as vertical lifts,
turntables, high speed conveyors etc. all have
unique design and safety requirements and should
be evaluated individually.

E0032544Rev090710
BELT TRACKING
WARNING
Only qualified personnel should be allowed to track
the belt. Use caution since conveyor must be run
during the tracking procedure.
ALL PULLEYS AND SNUBBERS MUST BE
SQUARE and conveyor must be level prior to
tracking the belt. Align the 3/8” square in the cam
and snubber bracket with the corresponding square
in the bed frame. (See “Conveyor Set-up” section).
Conveyor must be wired to run the correct direction.
Belt should be tensioned tight enough to drive the
heaviest product.
Belt tracking is accomplished using either the
tracking cams or snubber tracking brackets.

E0032544Rev090710
CRUZbelt is slightly different to track than other
conveyor. Since the belt is only 7/16” narrower than
the between frame dimension, some belt contact
with the side frame is expected. However, the belt
must not be allowed to contact the frame near any
end pulley or snubber.
CAUTION
Belt must not be allowed to contact the side frame
near an end pulley or a snubber.
Some basic tracking information:
•The belt moves TOWARD the end of a
pulley it contacts first.
•Use snubber tracking brackets before using
tracking cams. End pulley tracking is used
as a last resort.
•Tracking brackets and cams only affect belt
DOWNSTREAM of the device. Find the
nearest bracket or cam upstream from the
problem area and adjust as shown.
•Adjust bracket or cam slightly and watch belt
for several revolutions before continuing.
CAUTION
CRUZbelt conveyor must be used with
mono-filament belting. Use of any other belting
will damage conveyor. Consult your MHS
Conveyor distributor for belt specifications.

E0032544Rev090710
COMMISSIONING OF EQUIPMENT
GENERAL
Commissioning of the equipment can best be
defined as the final adjustments and test of the
installed equipment required for its proper operation.
The need for commissioning is inherent, since the
individual components of equipment are brought
together at the installation site to operate as a
system.
Mechanical and electrical commissioning is most
often carried out simultaneously. Commissioning
must simulate the actual operation of the system as
close as possible to demonstrate the ability to
perform reliably at the specified rate in the
prescribed operational sequence.
During the Commissioning Phase, it is necessary to
load the equipment with product to be conveyed,
which provides the means of detecting those areas
requiring adjustment. Personnel will be required to
support operational functions. This may serve as
part of operator training and familiarity with the
system. During the commissioning activity, special
attention should be directed toward personnel
safety. No unnecessary risks should be taken that
would endanger the safety of any personnel. All
personnel must familiarize themselves with all safety
features of the system such as emergency stops
and motor disconnects.
MECHANICAL STATIC CHECKOUT
(No power to the conveyor.)
1. Follow the belt path through the entire conveyor.
2. Visually inspect the installation. Is the conveyor
straight? Is the conveyor reasonably level from
side to side? From end to end?
3. Check guard rail clearance to product.
4. Eliminate all catch points.
5. Check conveyor elevations.
6. All bolts and set screws tight.
7. Check product clearance to overhead structures.
8. Simulate all operational functions with actual
product.
9. All guards in place with proper clearance.
10. All OSHA required guards in place on walkways,
catwalks, ladder-ways, floor openings, etc.
11. All labels and warning signs in proper place,
unobstructed.
MECHANICAL DYNAMIC CHECKOUT
(Power to the conveyor, but no product on it.)
1. Turn the motor ON. With the belt moving make
sure each belt has proper tension.
2. Check the belt tracking.

CRUZbelt

E0032544Rev090710
PREVENTIVE MAINTENANCE
GENERAL:
Preventive maintenance includes lubrication,
adjustment of equipment, and replacing or repairing
parts before failure.
All maintenance should be recorded in a log. This
should show what was serviced and when. The log
can then be used to trouble-shoot any systemic
problems.
WARNING
Do not perform any maintenance until the conveyor
power is locked out and cannot be turned on by any
person other than the one performing the
maintenance. If more than one person is working on
the conveyor, each person must have a lock on the
power. Any air lines in the work area should also be
turned off.
Make sure personnel are clear of the conveyor
before starting. All guards must be in place before
starting.
GEARMOTOR:
The drive unit should be checked monthly. Check
the motor gear case for leaking seals. Check fluid
level and fill with ISO VG220 mineral oil if necessary.
Check breather on the gear case.
CHAINS AND SPROCKETS:
Chains and sprockets should be checked monthly.
If either the sprockets or the chain are worn, both
should be replaced. Sprockets must be checked for
alignment with a straight edge. Clean the chain with
a non-flammable solvent and lubricate with 30W
synthetic oil. A brush is recommended for oil
application.
Check chain tension after initial run-in and then
monthly. Tension should be slightly slack, as
shown:
3/16"-1/4"
CHAIN
3/16"-1/4"
ALLOWABLE CHAIN SLACK
ROLLERS:
Inspect rollers periodically for debris build-up.
BELTS:
Belts normally need very little care. Clean monthly
with compressed air or a stiff brush. Clean bi-
annually with water and detergent.
CAUTION
Do not use petroleum-based products
to clean the belt.
REGREASABLE BEARINGS:
The drive unit and power take-off have regreasable
bearings. These bearings should be lubricated
every six months.
