The nut has several advantages, it can easily be located into the profile and automatically positions itself when the screw is turned 90 degrees clockwise. When in this position the bracket being fixed can be adjusted as required and locked by turning the screw further clockwise. To remove the bracket the fixing screw is turned anti-clockwise until the nut is in line with the profile slot. What does the standard say? Patented assembly function The European safety distance standard EN ISO 13857 provides information on acceptable safety distances in hazardous areas. These figures give examples of the safety distances required for two different fencing heights, where the risk is considered to be low if somebody reaches into the hazardous area. If there is a risk of direct injury and/or personal can be dragged into the hazardous area the safety distances must be increased. For accepted heights and distances please refer to EN ISO 13857 and other relevant standards/regulations. When mesh is used there must be a minimum distance of 200 mm (for persons older than 14 years) for a mesh size of 40x40 mm. For shorter distances and for noise reduction, polycarbonate sheet should be considered. When the fence shall protect for example a robot cell, the fence should be placed with a minimum distance of 500 mm between the guard fence and the moving machine part which reaches the furthest (according ...... ...... ............ .............. .......... ................ ........ ........................ ............ has to be space between the fence and moving parts to prevent the operator from being squeezed between them. Jokab Safety will be pleased to advise on guarding design and safety distances required. Safety distance for 1600 mm guarding with standard mesh. Safety distance for 2000 mm guarding with solid screens (e.g. polycarbonate sheet). Quick-Guard is a fencing system which is designed to manage the requirements from a safety perspective. It manages to stop machine parts and material that, during a malfunction, can be thrown against the fence. We have made collision tests with a large industrial robot, ABB Irb 6600, which was driven into the fence at a pace of 3 m/s. Both our Standard and Express fencing system withstood this. Thanks to our patented net-lock, both net and polycarbonate panels remained firmly attached to the aluminum profile. A video showing these tests is available on our website. In our tension-tests of up to 500 kg, both net and polycarbonate panels also remained firmly in the aluminum profiles. The fence was deformed during the collision but it sprung back, with some deformation as a result.

Then tighten the screw clockwise in the usual way. The nut will then automatically mechanically lock the fixture into the profile. In our pulling tests of up to 500 kg, both mesh and polycarbonate panels remained firmly attached to the the profile. ................................................................................Fittings that do not have a cast-in tab can be provided with a centring washer.
