BELT INSTALLATION
The relative position of the top
and bottom covers or surfaces of the belt should be considered when
positioning the roll for threading.
Once the roll of belting has been brought to the point of installation, it
should be mounted on a shaft for purposes of unrolling and threading onto
the conveyor.
In some cases, (where head room does not permit maneuvering a roll) the belt
may have to be pulled off the roll and reefed. Great care should be
exercised to see that the loops have large bends to avoid kinking or placing
undue strain on the belt. Weight should never be placed on the belt when it
is in a reefed position.
Another method of handling belting under certain conditions would be to lay
the roll on a turntable with a vertical spindle.
The belting should now be pulled onto the conveyor by either attaching it to
one end of the old belt which has been cut or in the case of a new
installation, by threading by hand, or by first-threading a rope or cable
around the idlers and pulleys and subsequently connecting that cable or rope
to the new belt by means of a clamp which will evenly distribute the
tensile load over the width of the belt as shown in the following
sketch. "Come-alongs" which do not evenly distribute the tensile
load over the width of the belt can cause damage to the new belt which, can
result in poor tracking characteristics.
If you are not present during the installation of the belt, double-check the
belt ends and look for "comealong" damage.
BELT FASTENERS
Endless splices are occasionally used on conveyors. However, by far the
most common method of joining belt ends is the metal fastener such as the
"Clipper" types or the "Alligator" constructions as well
as others. Fastener manufacturers catalogs should be consulted for proper
size and method of application.

SAFETY BULLETIN
This notice is issued to advise you that some previously
accepted shop practices may not be keeping up with
changing Federal and State Safety and Health Standards. Your current shop
practices may not emphasize the need for
proper precautions to insure safe operation and use of machines, tools,
automatic loaders and allied equipment
and/or warn against the use of certain solvents or other cleaning substances
that are now considered unsafe or prohibited by
law. Since many shop practices may not reflect current safety
practice and procedures, particularly with regard to the safe operation of
equipment, it is important that you
review your practices to ensure compliance with Federal and State Safety and
Health Standards.
IMPORTANT
The operation of any machine or power-operated device can
be extremely hazardous unless proper safety precautions
are strictly observed. Observe the following safety precautions:
Always be sure proper
guarding is in place for all pinch, catch, shear, crush and nip points.
Always be sure that
all personnel are clear of the equipment before starting it.
Always be sure the
equipment is properly grounded.
Always turn the main
electrical panel off and lock it out in accordance with published lockout/
tagout procedures prior to making adjustments,
repairs, and maintenance.
Always wear
appropriate protective equipment such as safety glasses, safety shoes,
hearing protection and hard hats.
Always keep chemical
and flammable material away from electrical or operating equipment.
Always maintain a
safe work area that is free from slipping and tripping hazards.
Always be sure
appropriate safety devices are used when providing maintenance and repairs
to all equipment.
Never exceed the
rated capacity of a machine or tool.
Never modify
machinery in any way without prior written approval of the Besser
Engineering Department.
Never operate
equipment unless proper maintenance has been regularly performed.
Never operate any
equipment if unusual or excessive noise or vibration occurs.
Never operate any
equipment while any part of the body is in the proximity of potentially
hazardous areas.
Never use any toxic
flammable substance as a solvent cleaner.
Never allow the
operation or repair of equipment by untrained personnel.
Never climb or stand
on equipment when it is in operation.
It is important that you review
Federal and State Safety and Health Standards on a continual basis. All
shop supervisors, maintenance personnel, machine
operators, tool operators, and any other person involved
in the setup, operation, maintenance, repair or adjustment of Besser-built
equipment should read and understand this
bulletin and Federal and State Safety and Health Standards on which this
bulletin is based. |
