1.0 SCOPE.
This specification covers the unpacking, handling, operation and maintenance for
SPIRACON TM Roller Screws manufactured by Power Jacks.
2.0
SAFETY
The Power Jacks Spiracon roller screw and nut serves for the positioning, transporting,
feeding, thrusting, lifting, unloading, clamping, gripping and compressing of loads,
tooling and work pieces. Since it can be used in so many different ways, it is the user
who must be responsible for the safety of the application concerned.
The user must ensure that the mounting of the Spiracon roller screw will not incur a
hazard or injury to persons and/or damage to materials. If it is required to install a
Spiracon roller screw in a region that is accessible to persons, then it must be installed
and guarded so that no person can be endangered while it is in operation.
The Spiracon roller screw must be operated within the defined stroke and must not be
driven into end stops. Limit switches should be fitted to the application to prevent this
from happening.
3.0
UNPACKING.
Remove the banding from around the container. Remove and discard in a safe place
any desiccant and plastic bags within the container. Lift the screws with soft slings
around the Spiracon roller screw using a spreader bar to reduce the screw deflection
while lifting.
WARNING - The Spiracon nut has a high efficiency and will travel along the
screw under its own weight if the Spiracon roller screw - nut combination is tilted
off the horizontal.
If the Spiracon roller screw is to be lifted into the vertical position then remove the
Spiracon roller nut or attach a collar to the screw to prevent the Spiracon roller nut
travelling down the screw under its own weight.
4.0
INSTALLATION.
The Spiracon nut can be removed from the screw for installation or maintenance
purposes.
It is recommended that the Spiracon roller screw be protected from contamination and
debris when installed by fitting covers or expanding bellows.
When installing the Spiracon roller screw into the position use soft slings as required
wrapped around the screw, ref above.
WARNING – Do not use wire ropes or chains to handle Spiracon roller screw.
