Summary
[edit]DescriptionRailwayTestCar 002.jpg |
The design shown consists of eight 10,000 lb. weights; four 2500 lb. weights; 10,000 lbs. of 50 lb. weights, and a truck used to carry the test load on the rails, which is in itself 5,000 lbs, as well as small auxiliary balances and weights giving this vehicle a total weight of over 105,000 lbs. Small weights are furnished which run down to 1/10,000 of a pound. Only decimal sub-divisions of a pound are used in this work. Power for handling the weights is furnished by an electrical generator driven by a gasoline engine. When in use, teh car is set a short distance from the end of the scale, the end doors of the car are opened, and the overhead crane rails are advanced by means of a motor until they overhang the track by the required amount. The truck is then connected to the crane and lifted from its position in the car and placed on the rails outside. This is then followed by weights until the first test load is ready. A cable is then connected to the truck and by means of a motor forming a part of the truck, the truck and test load are moved from place to place on the car. When the run is completed with this load, other weights are added, and the observations repeated on the higher loads for the different positions on the scale. |
