Abstract
PURPOSE: To make a high-precision drop test by an easy work by releasing the hold of a testing wheel and axle by a releasing handle after holding temporarily the testing wheel and axle, which is raised by a manual system, by an operation pawl in the dynamic characteristic test of a railroad track.
CONSTITUTION: Outrigger 3 which lifts truck A and can fix truck A is fitted to truck frame 3, and manual winch 7 which can cause testing wheel and axle 10 to ascend and descend through wire 8 and pulley 9 is provided, and operation pawl 11 which can hold temporarily wheel and axle 10 is linked with operation lever 16 through levers 12 and 14 and arms 13 and 15. Then, after lifting truck A, which is stopped in a desired position, by outrigger 3 and causing wheel and axle 10 to ascend by winch 7, lever 16 is pulled to this side, and operation pawl 11 is lifted and set, and winch 7 is returned, thus putting wheel and axle 10 on truck 11. Next, in case of test, wheel and axle 10 presses downward operation pawl 11, which becomes free, and drops when releasing handle 17 is operated to release lever 16, thereby performing the test.
