Shocks, Impacts, Vibrations, and Tilts: How to Monitor and Indicate Them
Pallets are subjected to impact whenever they are dropped from a crane, knocked by a forklift, or bounced over uneven roads (or shock). Vibrations may propagate within cargo if it is subjected to the rumbling of a ship's engine, the hum of a truck, the tremors of a reefer's condenser, or if it is operating itself. Damage may occur from automated tilt when perishable goods are kept in warehouses, loaded into containers, or transported to box trucks for final-mile delivery. Indicators and Sensors However, logistics monitoring should take into account more than just impact, tilt, and vibration when assessing damage. The choice between a monitor and an indication is another consideration. Monitors Most electronic shock monitors have to be powered (often by batteries) in order to measure shock events along one or more axes. So long as they have electricity, these monitors will keep track of any shocks that occur in the area. Indicators But not all packages need round-the-clock att...
