The load capacity and towing capacity of a burden carrier cannot be combined. The towing
capacity is reduced as weight is added to the burden carrier. This weight includes the passengers
and optional equipment as well as the load on the deck.
The formula for calculating reduced towing capacity DBP is:
Reduced DBP = DBP - Vl * (DBP/Vc) where:
•
Vc = Vehicle Rated Capacity
• DBP = Normal Draw Bar Pull specification
•
Vl = Vehicle Load (includes passengers and options)
The weight that the vehicle can pull can be calculated based on the DBP. This capacity would be
for a single standard 4-wheel trailer with a front steer axle and includes the weight of the trailer.
•
Level Surface: Towed Weight = DBP * 50
•
Up a grade:
Towed Weight = DBP/(2 + %g) * 100 where %g = the percent of grade
