The invention discloses a mast luffing system for a crane and the crane. The mast luffing system comprises a controller, a display, a handle, a luffing motor and a mast jacking oil cylinder, wherein the display and the handle are connected with the controller respectively, and the luffing motor and the mast jacking oil cylinder are controlled by the controller. According to the mast luffing system for the crane and the crane disclosed by the invention, the working efficiency of luffing action of a mast is improved, the error probability caused by human factors is reduced, and the labor cost is lowered by only needing one man to carry out operation under the working condition; meanwhile, the accident that the mast is jacked to be bent as the pressure of the mast jacking oil cylinder is larger under the pulling mode of the mast is also avoided; the phenomenon of luffing hoisting and disorder cable caused by small pressure of the mast jacking oil cylinder under the recouping mode of the mast is also avoided, and the mast luffing system for the crane and the crane are stable in performance and are safe and reliable.
