WEIGHING FREIGHT CARS BY THE TWO-DRAFT METHOD

In this report on the two-draft method of weighing freight cars only the first method is covered: Two-draft gravity motion weighing uncoupled. Both of the methods are suitable for weighing standard two-axle-truck freight cars of 29-ft inside length or longer. Some of the advantages of this method are: Cars may be weighed at a rate of three cars per minute. Human errors in weighing are reduced. Besides determining if a complete car is overloaded, information concerning the overload by individual trucks is given at the time of weighing. Track scales with specifictions for two-section knife-edge railway scales equipped with reqular weigh beam and an automatic printer recorder adapted to motion must be used. The weigh beam is used for testing, checking the recorder, and static weighing. It is cut out when using the recorder for weighing in motion. Each truck weight of a car is automatically printed on a tape in 100-lb increments. Test information covering two-draft gravity motion weighing is tabulated.
