The typical airport baggage type towing tractor is rated at 4,000 DBP. (Draw bar pull) so it can safely tow and stop around 40,000 to 50,000 lbs. All of these tractors can also have their rated draw bar pull increased to 5,000 lbs. simply by adding the necessary counterweight. A 5,000 lb. DBP rated tractor can safely handle loads up to 60,000 lbs approximately. Things such as terrain, weather conditions, and grade will obviously have negative effects on the tractors DBP. We can help determine the right size capacity tractor once we hear from the customer with their planned use for the tractor.What we refer to as airport type tractor can also, of course, be used for hundreds of applications besides on the airport.
