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.
