there is a formula which can be used to accurately calculate the position of the fifth wheel but you need to have a few details about the trailer and tow vehicle. you need to know how much weight is transferred onto the fifth wheel when laden by the trailer. you need to know the unladen weight of the towing vehicle and the unladen weight on each axle. you also need to know the maximum weight allowed on each axle. you need to know the wheelbase of the towing vehicle. loadbase is the distance from the fifth wheel to the front axle the formula is weight transferred onto front axle = wheelbase / loadbase* weight transferred onto the fifth wheel you can the play around with the loadbase number to achieve the optimum weight distribution onto the front and rear axles. ideally you want to have weight transferred onto the front and rear axles in the same ratio as the manufacturers maximum gross weights. eg max weight on steer of 3 tonnes and 6 tonnes on the rear indicates a 12 ratio. we used extensions of this basic formula to achieve maximum loading on b double fuel tankers with 8 compartments with varying fuel density to ensure we max loaded to legal limts every load. if you use pounds then use inches if you use kilogrammes use centimetres. dont mix your avoirdupois with your metrics. a fifth-wheel trailer is one that has a hitch that connects to the towing vehicle at a point above the rear axle of the towing vehicle - not at a point on the rear of the vehicle as with a pull-behind trailer. for example this is a 5th wheel http//www.theironworker.com/fifth%20wheel%20trailer.jpg my question concerns position of the point of attachment lets say the position of the king pin. for normal pulling of the trailer where is the best point to have the king pin should it be directly over the axle of the towing vehicle or should it be ahead of the axle if ahead by how much in what ways does handling change if the position of the king pin is changed this page http//www.etrailer.com/faq/fifthwheelfaq.asp discusses using a slider arrangement to move the king pin for maneuverability. it doesn t discuss the optimum position for towing. instructions that came with a hitch say to mount 0 to 6 inches ahead of the axle but provides no further information. -- |||||||||||||||| nehmo sergheyev |||||||||||||||| .
