Special equipment
EDK25-372
<space=1em><b>Design</b>
<space=1em>The crane consists of a lower platform of a welded structure on two three-axle bogies with pneumatic and hand brakes. Each bogie has one axle equipped with a gear reducer with a gear transmission for moving the crane under its own power. Six hydraulic outriggers are installed on the frame for stabilization when working at large boom extensions and with a large load.
<space=1em>An intermediate platform is installed on the lower frame, which can move along the crane. It contains a rotating platform with a diesel-electric unit. On one side, it has mounts for a welded boom with a load hook, and on the other, a folding platform for retractable counterweights. The crane is equipped with two mobile counterweights with a total weight of <nobr>5.3 t</nobr>, which have three positions. In the rearmost position, the crane can work with outriggers, in the <nobr>middle —</nobr> without them, and in the extreme forward position it can be transported.
<space=1em><b>Crane Features</b>
<space=1em>The design uses an intermediate platform supported by eight rollers, two in a cage. Brackets are attached to the outside of the cage. On the inside, they have rollers that enter under the shelf of the main beam of the lower frame and prevent the intermediate platform from tipping over. The rotating part moves along the lower frame by <nobr>8.9 m</nobr>, which allows one crane installation to service a site of <nobr>41 × 32 m</nobr>.
<space=1em>The lifting capacity depends on the boom reach and the position of the counterweights. <nobr>Maximum —</nobr> <nobr>25 t</nobr>. The crane is equipped with a diesel engine with a capacity of <nobr>100 hp</nobr>, driving an electric generator with a capacity of <nobr>48 kW</nobr>. Three-phase power voltage, <nobr>380 V</nobr>. Minimum radius of passable <nobr>curves —</nobr> <nobr>80 m</nobr>, length over <nobr>buffers —</nobr> <nobr>13,620 mm</nobr>, crane weight in transport <nobr>position —</nobr> <nobr>106 t</nobr>. During transportation, the boom is placed on a special support installed on the under-boom platform, and the hooks with clips are placed on the platform floor.

<space=1em>Railway 25-ton cranes are designed for emergency repair, assembly, loading and unloading operations. A representative of this class of cranes, the EDK25 crane, is typical of the 1950s and 1960s. It was fundamentally different from the cranes built before the war and in the early 1950s due to the transition from a steam power plant and mechanical drive to a diesel-electric drive. This greatly simplified both the mechanical part of the crane and its maintenance, and most importantly, it became easier to operate the mechanisms. They switched to a hydraulic drive in crane control in the early 1970s. This type of drive is still the main one today. It allows for smoother and more accurate work on moving loads. <space=1em>A special feature of the EDK25 crane is the presence of an intermediate platform on which the rotating part with the boom is located. The platform has the ability to move along the main frame by 8.9 m. This allows one crane installation to service a 41x32 m site. <space=1em>The crane's lifting capacity depends on the boom reach and the position of the counterweights. The maximum lifting capacity is 25 t on the main hook and 10 t on the auxiliary hook. <space=1em>The rail-mounted crane was built jointly at the Kirov Plant in Leipzig and the VEB LOWA railcar plant in Weimar (GDR) in 1953. <space=1em>The EDK25-372 rail crane was delivered to the museum from recovery train No. 4021 (Tver) of the October Railway in 1996.
