The invention discloses a beam type lifting appliance, which relates to the field of lifting appliances, and comprises a longitudinal beam assembly and a cross beam assembly, the longitudinal beam assembly comprises a longitudinal beam body and a longitudinal rotating shaft; the longitudinal rotating shaft is arranged in the longitudinal beam body, the longitudinal rotating shaft is in running fit relative to the longitudinal beam body, at least one end of the longitudinal rotating shaft extends to the outside of the longitudinal beam body, and first threaded sections with opposite threads are arranged at the two ends of the longitudinal rotating shaft respectively; a longitudinal moving strip-shaped hole parallel to the longitudinal rotating shaft is formed in the side wall of the longitudinal beam body; the cross beam assembly comprises a first sliding block, a first lifting lug and a cross beam body; the first threaded sections are in threaded fit with the first sliding blocks correspondingly. The first lifting lug is arranged outside the longitudinal beam body in a sliding fit mode, the first lifting lug is connected with the first sliding block through the longitudinal moving strip-shaped hole, and the lower portion of the first lifting lug is connected with the middle of the transverse beam body. Rapid adjustment of the transverse span and the longitudinal span can be achieved, and the adjustment efficiency is higher.
