Шпалоподбойка ЭШП9М3 is designed to compact the ballast under the railway track sleepers for all types of repairs and current track maintenance. Tampers manufactured by JSC Kalugatransmash today are the absolute leader in the Russian railways market due to their light weight, ergonomic design and reliability of the electric vibrator. Twenty years of evolution of the tamper made it possible to achieve not only the minimum weight of the product, but also the lowest vibration on the handles during operation.
