Known fire avtofoam lift, manufactured in accordance with GOST R 53330-2009 "Fire avtofoam lifts. General technical requirements. Test Methods" and equipped with a rotary boom device, a fire monitor mounted on the top of the boom device, a fire pump with an inlet pipe with a shutter and a pressure single-flow hydraulic communication containing a pressure manifold with a central pressure pipe connected to the monitor barrel with a shutter and with right and left side pipes with shutters, displayed on both sides of the fire autofoam lifter.

The disadvantage of this fire-fighting auto-foam lifter is that it has a pressure single-flow hydraulic communication for the movement of the hydraulic flow in only one direction from the inlet pipe of the fire pump to the fire monitor at the top of the boom device and it does not have a system for reversing the movement of the hydraulic flow in the opposite direction, due to which it cannot operate as a pump-and-hose fire truck, a fire truck pump station, or a pump truck station.

The prototype of the proposed utility model is a multifunctional fire-fighting foam lifter (utility model patent No. RU 198730 U1 "Multifunctional fire-fighting foam lifter". Patent holder: Limited Liability Company "Center for New Fire and Special Equipment" (RU). Published on July 23, 2020, Bull. No. 21 ), containing a rotary boom device, a fire pump with an inlet pipe with a shutter and an outlet manifold with a central pressure pipe with a shutter and two side pressure pipes with a shutter, two-flow hydraulic communication is used with the installation of a reversible pipeline with a shutter, connected at one end to the inlet pipe, the other end with a central discharge pipe of a fire pump, with the possibility of installing a removable fire monitor or a removable submersible pump on the top of the boom device.
