YQB-250 hydraulic derailleur
The YQB-250 hydraulic derailleur is mainly designed to adapt to the development of railway transportation and the expansion of transportation capacity in recent years. Many lines have already laid 60kg/m or 75kg/m steel rails and seamless tracks, requiring large tonnage derailleurs.
Therefore, the YQB-250 hydraulic derailleur has a high derailment force and can fully meet the maintenance needs of 50kg/m, 60kg/m, 75kg/m steel rails and seamless tracks. It is the latest hydraulic derailleur with four levels of force enhancement.
