These hoist rings have full swivel and pivot action and can take the full load from any direction. An integrated spring holds the ring in any position. The working load limit is specified on the hoist ring. This applies to the most unfavourable load rating (see table). The test load is 2.5 times the maximum permissible load. With captive but removable hexagon screw. The hoist rings corresponding to the Machinery Directive and are BG certified.
