Service truck trolleys are designed for refueling bypassing various objects with gaseous nitrogen, air or oxygen with a pressure of 2.4 to 30.0 MPa (24 to 300 kgf / cm2).
The service truck trolley consists of an automobile semitrailer and a housing fixed on it, in which gas cylinders, a remote control, filling sleeves and a set of spare parts, tools and devices are placed.
