Car height adjusting unit

Abstract

Abstract PURPOSE:To facilitate the getting in or getting off of men and the loading or unloading of cargoes by adjusting the height to an optimum value in accordance with the set of a hand brake faster as compared with the lag time of car height adjustment while the car is running. CONSTITUTION:When a hand brake detection switch 70 is opened (hand braked condition), a lamp 80 is turned off and a high level (H) is applied to an OR gate OR2, therefore, the output (i) of a clock exchange gate CEG is the output pulse of the Q0 terminal of a counter CO1. As a result, under a hand braked condition, the clock exchange gate CEG applies a short period pulse to a energizing unit 220 as a clock pulse (i), but under the other condition, the output of the OR gate OR2becomes zero, and the gate CEG applies a long period pulse to the energizing unit 220 as the clock pulse (i). Accordinly, the car height adjustment can be performed quickly while the car is at a halt.
