For this reason, it is necessary to constantly check its technical status and its use and to modify these wherever required with the aim of increasing the safety and simple handling for employees. Hailo has succeeded in achieving this in its new development, among other things as a result of the disconnecting feature of the Hailo PARTNER. This enables users to leave – if required – the ladder at any section of the ladder. He or she now no longer has to climb to the next-closed disconnection point. The new fall arrester has been approved for all three track types made from aluminium, steel and stainless steel. It is certified both in accordance with EN 353-1 and the “Recommendation for Use”, Vertical Group 11, CNB/P/11.073 and conforms to Directive 89/686/EEC.
