Filed: 1994-11-04
Abstract: PURPOSE: To prevent the slipping-off of a rear clamper due to the lowering of the tension of a wire rope for traction by capping a skater of a front clamper on a guide rail and mounting the front clamper. CONSTITUTION: A front clamper C is mounted on a skater S2 , and when a wire rope for traction Wa is driven, driving force is transmitted to a test vehicle V via the clamper C, a connection belt 31, a skater S1 and a connection wire 8. At the time of running start, a large force abruptly acts on the vehicle V, and a vehicle clearance is lowered. But the vehicle clearance is not lowered entirely, because the clamper C is mounted on the skater S2 capped on a guide rail. As a result, the rope Wa between the clamper C and the clamper 11 is not slipped off since a rear clamper 11 is not nearly flexed, its tension does not lower. At the time of start, even if the tension of the rope Wa is abruptly lowered, the looseness of the rope Wa rearward from the clamper C does not occur since the clamper C does not lower entirely, and the clamper 11 is not slipped off from the rope Wa .
