The invention discloses a work platform leveling system. The work platform leveling system comprises a dip angle sensor (8) arranged on a work platform (1), a work platform suspension bracket (2), a crank arm (7) and a swing cylinder (9), wherein the work platform suspension bracket (2) and the crank arm (7) are connected with the work platform (1); the swing cylinder (9) is installed in the connection hinged point of the crank arm (7) and the work platform suspension bracket (2). The swing cylinder (9) rotates to directly drive the work platform suspension bracket (2) and the work platform (1) to rotate to achieve leveling. The invention further discloses an elevating platform fire fighting truck using the work platform leveling system. The swing cylinder and the work platform are directly and rigidly connected without any transmission link or any interference factor, the system is high in mechanism leveling precision, stability and accuracy and good in rapidity, and the lag problem in the leveling process is greatly solved.
