8.2 ROUTINE INSPECTION
8.2.1 Scope
Division 40.0 of the A17.2 Manual covers inspections made on the moving walks exterior.
This section of the A17.2 Manual is quite complete and covers the majority of the items to
examine. However, the inspector must also check to see that all operating equipment is
functioning in its intended manner and that the appearance is acceptable to the rider.
8.2.2 Balustrades And Guards
Note any cracked or broken balustrade panels or ceiling intersection guards, if furnished.
Also note any screws or fasteners used to hold panels or moldings that are not flush or that have
burrs. Ceiling intersection guards should conform to dimensions shown in Figure 8-4.
8.2.3 Handrails
The handrails should be inspected, paying close attention to all splices and joints. Splices or
joints that open up can cause a severe finger pinch as the handrail goes around the newel.
Handrails should move in the same direction and at substantially the same speed as the steps.
Handrail tension should be checked by grasping a handrail at the landing. If it takes a great
amount of effort to stall the rail the tension is correct. If the handrail can be easily stalled, then it
should be readjusted.
8.2.4 Treadway
The treadway should be examined to determine whether grooves and surfaces are in good
condition, securely fastened in place, and are kept clean and free of debris.
8.2.4.1 Belt Type. Visually examine the exposed portion of the belt and belt splice for breaks
8.2.4.2 Belt Pallet Type. Visually examine belt splice and underside of the belt for breaks and
deterioration. Also check the pallet fastenings. They should not project above the surface of the
exposed treadway and the height of the pallets shall not vary more than 1/16 in. (1.6 mm) in
respect to one another.
