The invention discloses an engine automation installation vehicle which mainly comprises the following parts: a vehicle frame, a DC electric machine, an electromagnetic clutch, a worm and gear reducer, a handwheel subassembly, a chain-wheel chain, a rolling guide, a rear dragging plate, a left bracket subassembly, a right bracket subassembly, a diagonal draw bar, an H3 bracket, a front bracket, an eyelet bolt, a cushion bracket, a bottom guide subassembly, a butt cone subassembly, a universal trundle, a travel switch, and the like. When a certain-size airplane is digitally assembled, the engine automation installation vehicle can play the roles of transportation, auxiliary posture regulation and airplane engine installation. The engine automation installation vehicle has the advantages that: (1) electric drive or muscle drive can be used for pushing the rear dragging plate and the engine by connecting and disconnecting the electromagnetic clutch; (2) the drive smooth performance is improved by driving double chain wheels at both sides of the reducer; (3) the bottom guide subassembly is beneficial to aligning a top cone subassembly and a positioning hole, and the installation vehicle can be accurately positioned and fixed on a posture regulation bottom plate by a top cone subassembly.
