PERSONNEL GUARDS
Depending on the application, one or more of the following personnel protection
features is included in the design of this equipment (different states may vary on the
exact design and orientation of these features – IT IS IMPORTANT TO BECOME
FAMILIAR WHICH THE SPECIFIC CODE REQUIREMENTS OF YOUR STATE):
- GATES & ENCLOSURES: Required per ASME B20.1 to protect personnel from
inadvertent physical contact with a moving lift & moving load at all lift landings.
- CARRIAGE RAILINGS & SNAP CHAINS: Required per ASME B20.1 to protect
personnel whenever personnel walk onto the lift carriage when in the raised
position. Railings or side guards protect non-operating sides, snap chains protect
operating sides.
- CARRIAGE BACK-STOP PANELS: Additional safety feature recommended at all
upper levels to provide additional fixed guarding 2” (max.) away from & across all
unused, operating sides of the lift (typical with non-shaftway “Z” & 90 degree load
patterns).
NOTE: If the personnel guards are not purchased from Autoquip it is the
responsibility of the Owner to make sure that the personnel guards are in
compliance with the requirements set forth in ASME B20.1.
SHAFTWAY DOOR BARRIER BARS (where applicable)
Shaftway door barrier bars are designed to provide a secondary means of personnel
protection at the uppermost level landing of an FLM 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.
