Fall protection systems are subject to approval according to EN 353-1. After accidents, some of them fatal, occurred with conventional, simple systems in the past, this standard was improved in 2015. Based on the findings about the weaknesses of previous systems, the Twinstop\u00ae concept was developed long before the legal adaptation of the testing requirements.<\/p>

The simple mode of operation of our Twinstop\u00ae fall arrester guarantees safe and error-free handling. <\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

The fall arrester is approved according to EN 353-1:2014+A1:2017 for the rails of MKL-Technik GmbH, as well as several competitor rails – such as the guide rails or ladders of Safety Climbing Systems GmbH. This means that it can also be installed in existing rails with little effort.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

Step 3<\/h3>

If the speed becomes too high, the pawl has no time to spring back. The pawl moves against the catch notch and locks. The pawl is additionally pressed into the rail by the anchor point, which is mounted according to the back-pull principle. The anchor point is not directly connected to the pawl. This means that the pawl cannot be released again by careless movements of the climber. The positive guidance of the pawl ensures that the locking process is not affected by spring breakage or contamination.<\/p><\/div><\/div>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Our Twinstop\u00ae system fall arresters (runners or carriages) are tested and approved with the rails and ladders from Safety Climbing Systems GmbH (formerly Logaer Maschinenbau GmbH), which are primarily installed in Enercon wind turbines.<\/p>

The climber squats during the climb, e.g. to grab something, due to cardiovascular problems, nausea, etc. The rigid connection with the fall arrester shifts the climber’s center of gravity. In this position, it is increasingly difficult to get back to the top under your own steam. In extreme cases, the person falls into a “head-over-heels” position, the fall arrester unlocks, and the person falls.<\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

In the situation of low friction between the fall arrester and the guide rail, the climber and the fall arrester accelerate at the same rate in the event of a fall.<\/p>\n

This means that locking is no longer possible purely via the geometry of the fall arrester. The relatively weak spring of the fall arrester must pull the
mass of the climber towards the guide rail until the fall arrester locks in the fall arrester.
Tests by the British HSE show that the distance required for this can be so great that the impact force is far above the permitted 6 kN.<\/p>\n<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t

The operating principle of the MKL-Technik GmbH Twinstop\u00ae fall arrester is designed to be redundant and thus fail-safe, which we achieve by means of a mechanism positively guided in the C-profile of the guide rail. Compared to systems that operate exclusively on back pull or offer only simple functional safety, this type of speed-dependent release has several advantages, as shown here in comparison to our old monostop.<\/p>\n

Larger fall distances can occur if the guide rail is mounted overhanging.
\nDepending on the rail angle and design, the blocking function of the fall arrester can be completely disabled.<\/p>\n

As the blocking function of the Twinstop\u00ae fall arrester is speed-dependent – without the influence of external forces – the fall arrester function is also guaranteed in overhanging guide rails.
