The invention discloses a vehicle-mounted scaling ladder trolley of a fire fighting truck. The vehicle-mounted scaling ladder trolley of the fire fighting truck comprises a trolley body. A plurality of supports are arranged at the bottom of the trolley body side by side. Idler wheel structures are movably connected to the two ends of each support respectively. Baffles are arranged in the supports. Transverse springs are arranged between the baffles and the idler wheel structures. Each idler wheel structure comprises two idler wheels which are symmetrically arranged. A slideway matched with the idler wheel structures is arranged and is formed by sequentially connecting a plurality of sub-slideways which are arranged outside scaling ladder telescopic arms. A supporting beam is further arranged between the two paired scaling ladder telescopic arms of each section. Fixed pulleys are arranged on the supporting beams. A mooring rope connected to the front end of the trolley body is wound across the fixed pulleys and then is connected with a winding device on the fire fighting truck. A plurality of damping springs are further evenly distributed between the trolley body and the supports. Screws are further supported on the outer side of the trolley body in a rotary mode. A plurality of worm gears matched with the screws are arranged. Rotary shafts where the worm gears are located are all connected with bottom plates in the trolley body. The multiple bottom plates which are arranged side by side form an internal supporting plate of the trolley body.
