The invention relates to a full-life sling capable of being monitored and maintained, and belongs to the technical field of sling maintenance. The full-life sling comprises a sling body, a sling sheath, a connecting cylinder and a lower end anchor cup. The sling sheath is arranged on the sling body above the connecting cylinder in a sleeving mode, the sling body wrapped with the sling sheath is partially peeled off to expose steel wire bundles, a gap between the sling wire bundles is used as a dry air circulation gap D1, the steel wire bundles at the lower end of the sling body are scattered in a tapered shape and anchored in the lower end anchor cup to form a tapered casting body, a gap between the tapered casting body and the inner wall of the lower end anchor cup is used as a dry air circulation gap D2, and the dry air circulation gap D1 and the dry air circulation gap D2 communicate with each other in an up and down mode; and a viewport is formed in the sling sheath, the sling sheath is further provided with a dry air inlet, the dry air inlet directly communicates with the dry air circulation gap D1, a dry air outlet is formed in the outer wall of the lower end anchor cup, andthe dry air outlet communicates with the dry air circulation gap D2. The full-life sling makes targeted dry air maintenance, cures the sling disease, and restores a normal state of the sling.
