SAFETY INTERLOCKS/LATCHES - GATES OR DOORS
(where applicable)
These are electro/mechanical devices that prevent operation of the FREIGHTLIFT when
the gates or doors are left open on any level. They also prevent the gates or doors from
being opened at any level unless the platform carriage is in place at that floor level.
WARNING !
Never run the unit with the gates or doors open! Do not operate unit with
doors open or with the interlocks “defeated” (bypassed)!
SHAFTWAY DOOR BARRIER BARS (where applicable)
Shaftway door barrier bars are designed to provide a secondary means of personnel
protection at the upper level landing of an FLH shaftway installation. When the carriage
is not present at the upper level, the two barrier bars rest in permanent brackets
attached to both sides of the door frame on the outside (shaft side) of the upper level
door. The barrier bars form rigid barriers at approximately 24” and 48” above floor level.
In the unlikely event that the upper level door is able to be opened when the carriage is
not at the upper landing, the bars provide an additional means of personnel protection
against stepping or backing into the shaftway where the carriage could be assumed to
be present.
When properly installed, the barrier bars are lifted up and along their tracks by the
carriage as it approaches the upper landing until it is completely above the load height
as the lift stops. As the lift moves to the lower level, it carries the bars back to their
stationary brackets attached to the outside of the door.
WARNING !
Shaftway door barrier bars are not intended to be used as a primary means
of personnel protection. It is the responsibility of the operator to ensure
that all gate/door interlocks have been installed and are functioning
properly. Serious injury or death could result if upper level gates/doors
can be opened when the lift is not present at that level.
