If, however, the load overshoots after switching off the pressure, or moves slightly downward for any particular reason, the Safety Catcher is subjected to a partial load. In practice, this means that the load must first be raised before the Safety Catcher can be opened and before a movement in load direction is possible.<\/p>\n\n\n\n<p>This effect, often found to be disturbing and time-wasting, can be avoided by not bolting the Safety Catcher directly to the machine frame, but rather on top of a spring-base. For its working principle, see the Simulation with spring-base.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-vertical is-layout-flex wp-container-core-group-is-layout-fe9cc265 wp-block-group-is-layout-flex\">\n<p class=\"has-headline-h-4-font-size\"><strong>Downloads<\/strong><\/p>\n\n\n\n<div class=\"wp-block-buttons is-vertical is-content-justification-left is-layout-flex wp-container-core-buttons-is-layout-810fbbe0 wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button has-custom-width wp-block-button__width-100 is-style-download\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.sitema.de\/wp-content\/uploads\/Datenblatter\/EN\/Absturzsicherungen\/SITEMA-TI-A20-EN.pdf\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" width=\"20\" height=\"20\" class=\"wp-image-9245\" style=\"width: 20px;\" src=\"https:\/\/www.sitema.de\/wp-content\/uploads\/icons-symbole-banner\/picture_as_pdf.png\" alt=\"\"> A20 &#8211; Dimensions, Spring Base compressive load versions<\/a><\/div>\n\n\n\n<div class=\"wp-block-button has-custom-width wp-block-button__width-100 is-style-download\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/www.sitema.de\/wp-content\/uploads\/Datenblatter\/EN\/Absturzsicherungen\/SITEMA-TI-A21-EN.pdf\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" width=\"20\" height=\"20\" class=\"wp-image-9245\" style=\"width: 20px;\" src=\"https:\/\/www.sitema.de\/wp-content\/uploads\/icons-symbole-banner\/picture_as_pdf.png\" alt=\"\"> A21 &#8211; Dimensions, Spring Base tensile load versions<\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-container-core-group-is-layout-da604d14 wp-block-group-is-layout-constrained\" style=\"padding-top:0;padding-right:0;padding-bottom:0;padding-left:0\">\n<div class=\"wp-block-group has-global-padding is-layout-constrained wp-container-core-group-is-layout-19e250f3 wp-block-group-is-layout-constrained\">\n<h5 class=\"wp-block-heading has-headline-h-5-font-size\" style=\"margin-bottom:var(--wp--preset--spacing--2-rem)\">Advantages<\/h5>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Even if the load slowly sinks down during normal operation, e.g. due to a small leakage at the lifting actuators, it is not necessary to lift the load before any downward movement.<\/li>\n\n\n\n<li>The crucial safety criterion \u201cSafety Catcher can only be released if the rod is free of load&#8221;, is satisfied without restriction.<\/li>\n\n\n\n<li>The spring-base also compensates for any lateral misalignment between the load guide elements and the clamping rod.
