Clipping machine MMD

The introduction of high-speed railway lines in Russia has required engineers to implement not only new track-laying technologies but also modern rail fastening systems. One such solution is the Pandrol-350 anchor fastening system, also known as the FastClip resilient rail fastening system (PANDROL FASTCLIP). This type of fastening is ideally suited for railway lines where passenger trains can reach speeds of more than 250 km/h.

The Pandrol-350 rail fastening system (Pandrol FastClip) is supplied pre-assembled on the sleeper. After the sleepers have been laid and the rails installed, the fastening is brought into its working position by simply pressing the clip. The fastening has vandal-resistant characteristics and is extremely difficult to dismantle without special tools. Other advantages include the fact that, unlike bolted fastenings, the Pandrol FastClip anchor fastening (Pandrol-350) eliminates false torque, mechanical damage to or contamination of threads, reduces track-laying time and lowers track maintenance costs. Possible clip movement during operation is also eliminated. Stable rail clamping is ensured by the design of the fastening itself. Another important advantage is that concrete sleepers do not require holes when Pandrol-350 fastenings are used, eliminating internal stresses in the sleepers caused by water, oil or dirt entering the holes. The simple design and small number of components have made the Pandrol-350 fastening one of the most widely used systems in the global high-speed railway market. Electrical insulation, the absence of threaded connections and interchangeability of components all make the Pandrol-350 fastening a highly promising solution for the Russian Railways network.

However, the most important advantage of the Pandrol-350 fastening is its ease of maintenance. Only one operator with an MMD installation and removal machine manufactured by the Armavir-based KZDM plant is required to keep the entire track in excellent condition. The MMD machine does the work itself, as this unit was specifically designed for semi-automatic maintenance of tracks equipped with Pandrol-350 fastenings.

All railway professionals are familiar with Order No. 2270 dated November 12, 2012, which effectively became the regulatory document governing the assembly, installation and operation of railway tracks with Pandrol-350 (Pandrol FastClip) anchor rail fastenings on reinforced concrete sleepers within the Russian Railways network. To meet the modern track operation requirements set out in this document, we began not only to modernize our track maintenance tools but also to develop a fundamentally new solution: the modern, high-performance MMD installation and removal machine for routine maintenance of railway tracks equipped with Pandrol-350 fastenings. It is designed to mechanize maintenance operations involving the modern Pandrol-350 fastening system used for high-speed railways in Russia.

The plant’s engineering department developed the MMD small track machine from scratch within a short period of time. It enables the installation and removal of the relatively new Pandrol-type fastenings used in Russia. This reliable and high-speed machine can be used on all railway sections where the rail-sleeper grid is equipped with Pandrol FastClip (Pandrol-350) fastenings.
