Gestra VZ20 Rail Hook

System Description

The mechanic rail hook type VZ 20 is used to keep tank?car bottom valves open during loading and unloading – mainly those carrying pressure?liquefied gases. The rail hook serves as a safety link between the tank car and the loading plant. The common rail section, as used by the German railways, is type S 49 to DIN 5902. The rail hook is therefore suited for this rail section. To ensure reliable operation of the rail hook, a rail with this section is required at the loading plant. If the existing rail is not type S 49, it is possible to provide an auxiliary device on site for engaging the rail hook.
