Description of Applications
On-Highway vehicles operate exlusively on roads that are improved or normally paved. The following are some typical vocations: linehaul, pickup and delivery, beverage delivery, public service dump trucks, utility trucks, tank trucks and tour coaches.
Motor Homes as in recreational vehicles with living accomodations.
Severe Duty vehicles operate both on and off highway. The following are some typical applications: dump trucks, transit mixers, refuse trucks, all wheel drive public utility trucks, snow removal, yard spotter, concrete pumper, heavy equipment transport and other vocations with severe PTO applications.
Emergency Vehicles as in fire trucks that are typically designed to NFPA guidelines.
