Safety Standards
Safety Standards: All
power transmission drive systems should be adequately guarded under ANSI/ASME
B15.1-1984 standards and OSHA, subchapter O standards (Federal; vol. 39;
no.125; June 27, 1974; pgs. 23079-23733) or the applicable state or country
(outside the U.S.A.) safety standards. The following rules apply to the drive
systems, "Where breakage of a machine component can result in injury, provision
shall be made for appropriate containment of such component. When power
transmission apparatus' are stopped for servicing purposes, the power device
shall be locked out, in accordance with a generalized procedure, to protect
persons exposed to the apparatus from an unexpected start. When component
breakage may result in fragments being propelled, the apparatus should be
guarded and should be solid, not mesh."
Installation
Installation: The drive
system power should be disconnected or an interlock activated to avoid
accidental startup. Never install, adjust or maintain a POBCO
Snapidle® when the drive is in operation, or personal injury may occur.
Apply the bottom block and the top block of the POBCO Snapidle® to
the upper and lower chain strands. Tension the chain by means of the side
straps. Do not over tension the POBCO Snapidle®, this will result in
increased wear rate. Enough tension need only be applied to take out the slack
of the chain. When the drive is in operation the POBCO Snapidle®
will move back and forth on the chain periodically. If the proper tension is
applied the POBCO Snapidle® should tension the chain for the life of
the chain or the POBCO Snapidle®. Set the strap length with the
drive side chain tight and all the chain slack on the slack side. Please refer
to the first Selection Criteria drawing for
correct installation.
Maintenance
Maintenance: The
POBCO Snapidle® should be inspected visually under normal drive
maintenance procedures in order to verify wear. The POBCO Snapidle®
should be replaced before the chain wears through the plastic carriers. The
POBCO Snapidle® may be re-tensioned by adjusting the side straps. Do
not attempt this with a moving drive, personal injury may occur.
Replacement
Replacement:
POBCO recommends the replacement of the entire Snapidle®
unit, including the side straps. The straps will have been subjected to drive
stresses and may cause unit failure when replacement is necessary. POBCO
cannot warranty the Snapidle® if the unit is installed with used
strapping material and we strongly recommend that worn Snapidle®
units are used to replace new Snapidle® units. |
