The invention relates to the technical field of lifting equipment, in particular to an evaporator lifting appliance comprising a lifting hook device and a beam assembly which can be relatively rotated. The beam assembly and a steel wire rope are connected in the way of being capable of achieving stability during evaporator lifting and relatively rotated around a joint. The evaporator lifting appliance has the beneficial effects that by means of the arrangement, a lifting device and a beam short shaft of the beam assembly are rotationally connected; the beam assembly and a triangular connectionplate of the steel wire rope are rotationally connected through a beam inner long shaft inside the beam assembly; during evaporator lifting, since the steel wire rope can be rotated around the beam inner long shaft, the beam assembly can be rotated around the lifting hook device, various kinds of stress produced by slight movement of a lifted evaporator on the lifting appliance can be well eliminated, stress corrosion is avoided, and lifting safety is improved.
