The invention discloses a lifting device applied to construction equipment. The lifting device comprises a housing, a left partition plate, a right partition plate, a left chamber, a right chamber, alower spring, an upper spring, a left pulley, a right pulley, a crossbeam, a through hole, a steel cable, a bracket, a pulley, a rolling motor, a connecting block, a horizontal plate, a first rollingwheel, a second rolling wheel, a lifting block, a lifting rope, a lifting ring and a lifting hook. The bottom of a base plate is provided with universal wheels so that the lifting device can move randomly and can be arranged and processed conveniently; the lifting device is relatively small in size and can conveniently work in a relatively small place; a rotating column rotates inside a rotating chamber so as to realize the rotation of the overall lifting device; the lifting hook is used for hooking an object; the lifting device can move leftwards and rightwards by virtue of the first rollingwheel and the second rolling wheel; the rolling motor is used for driving the steel cable, so the height adjustment of the overall device can be realized; the lower spring and the upper spring are arranged to effectively realize a limiting effect; and the lifting device disclosed by the invention solves the problems existing in the background technology.
