The invention provides a universal sling for a heavy truck beam. The universal sling comprises a supporting base; the supporting base is slidably connected with an adjusting rod; the top end of the adjusting rod is fixedly connected with two fixing plates; the fixing plates are in an inverted J shape; a middle of a compaction device used for compressing the beam is hinged to the ends, away from the adjusting rod, of the bottoms of the fixing plates; the top of the compaction device is connected with a chain; a first bolt penetrates through the tops of the fixing plates to achieve connection through a first nut; and the chain is wound around the bottom of the first bolt and penetrates through a gap between the fixing plates. By means of the universal sling, the beams of different kinds anddimensions can be hoisted; the time loss caused when the sling is changed is avoided; the beam hoisting efficiency is improved; and the economic benefit is improved.
