The invention discloses a suspension derrick with high stability, which belongs to the technical field of suspension derricks and comprises a suspension frame, and a suspension column is mounted on the suspension frame. The device has the advantages that the servo motor drives the threaded shaft to rotate, the belt connecting set drives one threaded rod to rotate, the belt connecting piece drives the multiple threaded rods to rotate synchronously, and at the moment, the cover plates and the push blocks on the threaded shaft and the threaded rods move downwards; the cover plate and the push block move downwards to push the hollow column, the lower rotating head and the hollow earth-drilling rod to move downwards, then the hollow column, the lower rotating head and the hollow earth-drilling rod enter the ground, in this way, the stability degree of the suspension frame can be further increased, the stability of the suspension derrick is improved, and the capacity of the hollow column entering ...
