The invention relates to the technical field of lifting mechanical equipment, and discloses a double-motor type lifting arm which comprises a base, a storage platform, a first lifting set and a second lifting set. The first lifting set comprises a first driving motor fixed to the base, a first swing rod with one end fixed to a motor shaft of the first driving motor and a first pull rod rotationally connected with the other end of the first swing rod, and the end, away from the first swing rod, of the first pull rod is rotationally connected with the storage platform. The second lifting set comprises a second swing rod with one end rotationally connected with the base, a second driving motor fixed to the other end of the second swing rod and a second pull rod with one end fixed to a motor shaft of the second driving motor, and the other end of the second pull rod is rotationally connected with the storage platform. And a motor shaft of the first driving motor and a motor shaft of the second driving motor both have a self-locking function. The lifting arm has the effect of effectively prolonging the service life of the lifting arm.
