In accordance with the German DIN15435 standard, the uniform device of the lino back distance can always keep the equal distance between the two sides of the tile in the process of use, and completely avoid the phenomenon of floating the brake disc on one side brake liner because of the unequal distance, and there is a tile automatic follow up device. The main swing hinge points have self lubricating bearing, the transmission efficiency is high and the life is long. There is no need of lubrication in the process of use; the brake spring is arranged in the spring tube, and the brake torque scale is set on one side, the braking torque is directly displayed, the adjustment is convenient and direct, the non asbestos brake liner is inserted, the replacement is convenient and fast, the brake lining wear is automatically compensated and installed, and the distance of the tile and brake torque can be made. It can be kept constant in the process of use; some additional functions can be realized by adding additional devices; manual release device and release or closed limit switch can realize the normal release or closed signal display of brake; brake liner wear limit switch and automatic signal display when the brake linings wear to the limit. The Ed series actuator with time delay valve can delay the brake and brake smoothly.

　　Conditions of use: ambient temperature: -20 degrees C degrees C+50. The relative temperature of the air is not more than 90%. Generally used for three-phase AC power supply 50HZ, 380V (60HZ or different voltage can be produced as required, please explain the current order). The altitude is in accordance with the GB755-2000 standard. When less than -20 degrees C, the working fluid of the propeller is replaced with YH-10 aviation hydraulic oil or the heater is required according to the requirements, and details refer to the sample of the Ed propeller.
