Who does what
| Machine | Typical task | Where an edge is involved |
|---|---|---|
| Plow truck | Moving snow off pavement in lines | Cutting edge on the moldboard touches the surface |
| Rotary plow | Throwing deep or heavy snow clear | Mostly the rotor and housing; some designs have a lower edge near the surface |
| Broom | Final sweep of thin snow and slush | Brush elements, not a cutting edge |
| Loader with pusher or blade | Pushing piles and clearing aprons or gates | Bucket, blade or pusher edge |
Questions to ask for each machine
Which parts touch the pavement?
List them. Each is a wear item, and each can mark or damage lights and joints if it is set or worn wrongly.
What spares are held?
Match spares to the parts that touch the surface. A truck edge is no use to a broom, and the reverse.
How is wear checked?
Write down the inspection point and the replacement trigger for each machine. Keep them separate; a single line for the whole fleet hides differences.
Who decides when a machine stays in service?
Set the authority clearly. In a storm, the temptation is to keep running; a clear rule helps the shift lead say no.
Limits
Machine design varies by maker and model. Use the maker’s documentation to see what touches the surface on your own equipment, and follow airport and regulator requirements for surface condition and equipment readiness. The framing above only helps you organise the questions.
Why the split matters
Airports often run mixed fleets bought at different times. When a plan lists only trucks, brooms and rotary machines are left without a wear-part view. A short table like the one above, completed for your own fleet, keeps every surface-touching part on the inspection and spares lists.
Using the table in planning
Add two columns to your own copy: the spare you hold, and the lead time for a replacement as quoted by your supplier. Gaps jump out at once. A machine with no spare and a long lead time is a risk to be solved before the season, not during it.
Boundary: Machine designs vary and this article cites no standard or maker data; follow the maker’s documents and your airport’s own requirements.
