Locations of Key Safety Devices
Locations of Key Safety Devices
1) Cleat
Grooves in the Step's Floor Plate (and Riser for escalators) designed to prevent feet or foreign objects from getting caught between the Step (Pallet) and the Comb, or the Riser and the Step. Cleat
2) Drive Chain Safety Device
A safety device that operates to stop the escalator (moving walk) if the Drive Chain breaks or stretches beyond an allowable limit.
3) Step (Pallet) Chain Safety Device
A safety device that stops the escalator (moving walk) if the Step Chain (Pallet Chain) breaks or stretches beyond an allowable limit.
4) Curved Rail Safety Device (CRS; escalators only)
A safety device to stop the escalator when a Step has been dislocated on its riser side due to an object caught between the Skirt Guard and the Step, or between the Steps, or if an abnormality has been observed in the Step motion.
5) Low-Friction-Coefficient Resin on Skirt Guard
Friction-reducing resin coating on the Skirt Guard to reduce the chance of passengers stumbling when shoes come into contact with the Skirt Guard.
6) Skirt Guard Safety Device (SSS)
A safety device to stop the escalator (moving walk) if a shoe or other item becomes trapped in the gap between the Step (Pallet) and Skirt Guard.
7) Inlet Guard
A guard made of soft rubber, which fits over the outside of the handrail where it enters the Balustrade to keep a person’s fingers or hand, or any foreign object away from the handrail opening, to prevent injury. Inlet Guard
8) Emergency Stop Button
A button that immediately stops the escalator (moving walk) in emergency situations.
9) Handrail Safety Switch
A safety device that stops the escalator (moving walk) when the speed of the Moving Handrail and the Steps (Pallets) fail to synchronize.
10) Inlet Guard Switch
A safety device that stops escalator (moving walk) when physical contact is made with the inlet.Inlet Guard Switch (HGS)
11) Fire Shutter Switch (FSS)
A special feature installed only when a fire-prevention shutter is in the vicinity of the escalator (moving walk). The opening and shutting of the fire prevention shutter is synchronized with the escalator (moving walk), and the escalator (moving walk) cannot be started while the fire-prevention shutter is down.
