制动器是起重和运输机械的重要配套件,焦作制动器厂生产的 YTI 制动器用推动器是50年代产品,设计和工艺落后,产品性能差,只能垂直使用、而且密封不好,每小时工作次数为720次,使用寿命仅300万次左右。而联邦德国生产的 Ed 系列制动器用推动器具有80年代先进水平,在国际上处于领先地位,使用角度可以任意变换,密封性能也好,每小时工作次数为2000次,使用寿命可达2000万次,为该厂老产品的近7倍。为了促进产品的更新换代,1985年用170万马克从联邦德国 EMG 公司购买 Ed 系列制动
The brake is an important accessory for lifting and transportation machinery. The YTI brake actuator produced by the Jiaozuo Brake Factory is a product of the 1950s. Its design and process are backward, and its product performance is poor. It can only be used vertically, and the seal is not good. The number of hours worked per hour For 720 times, the service life is only about 3 million times. The Ed series brake actuators produced by the Federal Republic of Germany have an advanced level in the 1980s and are in a leading position in the world. The angle of use can be arbitrarily changed, and the sealing performance is also good. The number of hours of work per hour is 2000, and the service life can reach 20 million times. , nearly 7 times the old product of the plant. In order to promote the upgrading of products, in 1985, the company purchased the Ed series brakes from the Federal German EMG Corporation with 1.7 million marks.
