The invention discloses a lift used for constructional engineering and relates to the field of lifts. The lift comprises a lift body, wherein the lift body comprises two traction machines, a guide rail frame, a top beam, pulleys, a steel wire rope and lifting cages, wherein the top beam is arranged at the top of the guide rail frame; the four pulleys are symmetrically arranged on the top beam, wherein two pulleys are arranged at the bottom of the guide rail frame; the lifting cages are arranged on the two sides of the guide rail frame respectively; the two ends of the steel wire rope penetrate through the two pulleys and are connected with the lifting cages and the traction machines respectively; two guide rails are arranged on one face, which is in contact with each lifting cage, of the guide rail frame; rolling wheels are arranged at the corresponding positions of the side surfaces of the lifting cages and are clamped on the guide rails; the end part of the top beam is connected with the guide rail frame by steel rods between the top beam and the guide rail frame; protection walls are arranged at the peripheries of the lifting cages in the horizontal plane; the two steel rods can be used for balancing vertical drawing forces on the top beam by the lifting cages on the two sides, so as to prevent the top beam from being bent.
