The invention discloses application of a thruster and relates to the technical field of application of air transportation ground auxiliary equipment. Pin rollers, pin roller shafts, pin roller supports, pin roller springs, supports, a connecting rod, a traction support, a linear motor rotor and a linear motor stator are involved in the application. The application is characterized in that 1, when an aircraft need to take off, a pilot enters the aircraft and gives an instruction to the thruster of ground equipment after obtaining a takeoff instrument of a ground navigation management system; 2, a main bearing platform of a platform body drives the aircraft to the side of a slide; 3, the pilot gives the instruction to start the thruster, and the traction support of the thruster moves backwards along a rail of the thruster to drive the supports to move backwards; 4, the pin rollers of the thruster drive a main landing gear of the aircraft to move backwards; 5, the thruster pushes the aircraft down from the main bearing platform along a transition ramp and then resets.
