Disclosed is a lifting apparatus for electronic information engineering, the apparatus belonging to the technical field of electronic information engineering. The lifting apparatus comprises a base (7), wherein castors (8) are mounted at four corners of the bottom end of the base by means of bolts; an infrared distance meter (10) is mounted in the middle of an outer wall of the top end of the base by means of bolts; electric extensible supports (5) are mounted on two sides of the outer wall of the top end of the base by means of bolts; and a load-bearing platform (4) is mounted at the top ends of the two electric extensible supports by means of bolts. A pressing block (9) is placed at the bottom end inside a chamber, which pressing block improves the stability of the base. A storage battery (6) is placed on the top end of the pressing block, which storage battery is the backup for when there is a sudden power failure, which improves the flexibility of the apparatus in responding to emergencies. The bottom end of the load-bearing platform is mounted, in an embedded manner, with a pressure sensor (11) which senses the pressure from an object in real time, such that if the pressure exceeds a safety limit value, a handheld controller issues an alarm. In addition, when dealing with tall objects, an electric push rod (1) actuates an extensible protective cover (2) so as to prevent the object from shaking during a lifting process. The apparatus has simplified mechanisms and a high safety performance.
