Hazards To Personnel in Proximity to Shuttle Conveyors
Milnor automated laundering systems use automatic shuttle conveyors to transport goods among
the processing machines in the system. Depending on model, an automatic shuttle conveyor may
move in any of the following ways, in addition to running its conveyor belt(s):
• It may travel along (traverse) a line of machines (typically dryers).
• Its conveyor bed(s) may ascend and descend (elevate) within the machine frame.
• Its conveyor bed(s) may extend and retract within the machine frame.
• The conveyor bed and frame may pivot.
• Wet goods shuttles have a bucket that elevates and tilts.
These motions pose strike, crush, sever, and entrapment hazards to personnel in proximity to the
shuttle.
For the safety of personnel, owner/users must provide proximity safeguarding that
protects personnel from the moving shuttle.
