Abstract
PURPOSE: To prevent brake lining wear by releasing a stop brake gear by a direction change-over valve for brake so that the brake does not work while rotational speed in the hydraulic motor is more than a settled value.
CONSTITUTION: A brake 10 for a hydraulic motor 3 is worked by driving a hydraulic cylinder 11. The cylinder 11 is connected through a direction change-over valve 19 for brake to the oil pressure source 17. During larger moment of inertia for a revolving body revolved by the hydraulic motor 3, even if a counter-balance valve 6 comes to be at the neutral position n, a hydraulic pump 21 runs on, the brake 10 does not work with the valve 19 remained at the position b. When the rotational speed comes to be less than a settled rate, the valve 19 stands at the position (a) to operate the brake 10.
