Long drivelines can lead to component vibration or failure. As the driveline
approaches half critical speed, a vibration will occur that can damage driveline com-
ponents.
Table 10-1: Maximum Recommended Driveline Lengths below lists the maximum driv-
eline length using a safety factor of 42% of critical speed.
This table is based on a 0.134” (3.4mm) wall thickness. Although wall thickness does
not have a significant effect on drive shaft length for this calculation, it does have
some effect.
Extremely short drive lengths can also cause problems from excessive operating
angles. Use caution and conservative design values when utilizing air ride suspension
and short rear drivelines.
More information on fire apparatus drivelines can be found in Hale OEM Technical
Bulletin # 957. For application assistance and approval, contact a driveline equipment
manufacturer, such as Spicer/Dana or Merritor.
Note: Hale assumes no liability for any information provided under this heading “Driveline
Issues.” Driveline design and truck system integration is the responsibility of the apparatus
manufacturer. Failure to comply with the driveline parameters set forth can result in termina-
tion of Hale’s warranty on driveline related issues.
