Safety Application Example
Automated Lift Guarding
Application:
To guard an area around a lift used to
raise and lower auto bodies.
Description: A lift is used to raise and lower parts of an auto body between different
levels of the factory. The area around the lift is guarded with hard guard
fencing. A system is needed to guard the entrance and exit the auto body uses to
pass in and out of the area, and also to detect if a person is standing below
the lift.
The MINI-SCREEN is mounted horizontally just a few inches above the floor. This
provides an optical “safety mat” across the floor of the lift area.
The MICRO-SCREEN with muting is mounted across the opening to the lift area. The
QS18 pairs are mounted in an “X” pattern across the opening, and functions as
the muting devices for the MICRO-SCREEN. As the auto body passes out of the lift
area, it blocks the QS18 sensors first, which mutes the MICRO-SCREEN allowing
the auto body to pass out of the area without stopping transfer skid.
WARNING:
This application example depicts only
generalized guarding and should not be automatically treated as a solution for
any particular situation. Every guarding application has a unique set of safety
requirements which must be carefully examined. Extreme care is urged to ensure
that all safety and legal requirements are met and that all installation
instructions are followed.
In addition, any questions regarding safeguarding should be directed to the
factory’s own Safety Department or Safety Officer. No responsibility will be
taken for use of these examples which are only guidelines to the types of
equipment available.
