And the contractility ＞ wheel brake mechanism that provides of telescoping drive mechanism brakes specified dynamics, it utilizes the output of pulling force inductive switch to make
For signal to be transmitted, central processing unit real-time reception, from the detection signal of pulling force inductive switch, arranges telescoping drive mechanism
Working value.
