The invention relates to the technical field of mechanical lifting transmission and heavy load carrying, in particular to hydraulic lifting equipment which comprises an equipment body, a driving component, a cargo boom and a folding operating rod assembly. Wherein the folding operating rod assembly comprises a saddle, a rod body, a fixing sleeve and a pin shaft; the saddle is used for forming assembly fit with an equipment main body; the rod body is hinged to the saddle through a pin shaft. And the fixing sleeve takes the rod body as an assembly carrier and is movably sleeved, and the fixing sleeve and the saddle form detachable locking connection. When the rod body is in the unfolding operation state, the fixing sleeve limits the rod body to rotate and fold relative to the saddle through the locking effect, namely, the rod body and the saddle are fixed into a whole, so that the stability when an operator manipulates equipment is ensured; when the equipment needs to be stored and carried or the operation space is narrow, the locking connection between the fixing sleeve and the saddle is removed, the rod body can rotate and be folded relative to the saddle, the occupied size of the equipment is greatly reduced, storage and transportation are convenient, and the operation flexibility in the narrow space is improved.
