When mass and speed collide, enormous physical forces are generated that must be deflected. In order to perform a crash test safely for all participants in the test facility, safe braking of the test object is required.<\/p>\n

ERNST has developed two braking systems for this purpose, which are used accordingly depending on the test.<\/p>\n

Short rope brake<\/h2>\n

\"\"<\/p>\n

 <\/p>\n

\n

The braking system is characterized by a short rope and is installed in a compact unit.<\/p>\n

Due to the short rope length, this braking system is only used to brake an object in a defined way after the crash.<\/p>\n

The air-operated disc brake transmits the braking force to the object to be braked via a 75 mm wide polyamide band with max. 7% elongation.<\/p>\n

The retraction after a braking process is performed manually via hand crank.<\/p>\n

    Long rope brake<\/h2>\n

    \"\"<\/p>\n

     <\/p>\n

    The braking system is used with any moving test equipment \u2013 whether a mobile barrier or a test vehicle.<\/p>\n

    The long rope allows any test object to be safely braked both during the start-up phase and after the crash phase.<\/p>\n

    This uses a 12 mm robust steel cable, which is installed in a cable drum.<\/p>\n

    The retraction after a braking process is performed with a foot switch and electromagnetic coupling.<\/p>\n
