Section I. INTRODUCTION
General
8.1.1.1
This section contains PMCS requirements for the bridge. The PMCS tables contain
checks and services necessary to ensure that the bridge is ready for operation.
Using PMCS tables, perform maintenance at specified intervals.
8.1.1.2
Cleaning instructions and precautions. During PMCS keep the following general
maintenance procedures in mind:
(i)
Cleanliness. Dirt, grease, oil and debris may cause or cover a serious
problem. Clean all metal surfaces.
(ii)
Bolts, nuts and screws. Check bolts, nuts and screws for obvious looseness,
missing, bent, or broken condition. Look for chipped paint, bare metal, or rust
around bolt heads. If any part seems loose, tighten it, or have the part
repaired or replaced.
(iii)
Welds. Look for loose or chipped paint, rust, or gaps on welds. If a bad weld
is found, notify unit maintenance.
(iv)
Electrical wires and connectors. Look for cracked or broken insulation, bare
wires and loose or broken connectors. Tighten loose connectors and make
sure wires are in good shape. If a wire or connector is bad, notify unit
maintenance.
(v)
Fluid lines and fittings. Look for wear, damage and leaks, and make sure
clamps and fittings are tight. If a leak comes from a loose fitting or connector,
tighten it. If something is broken or worn out and can not be fixed with tools
available, notify unit maintenance.
