The invention discloses a pneumatic brake on a hoisting machine. The pneumatic brake on the hoisting machine comprises a hollow brake body and an elastic push rod connected with the hollow brake body,wherein the elastic push rod is annular; an inner cone hole is formed in the middle part of the elastic push rod; a plurality of parallel rollers are arranged in the inner cone hole; the rollers arearranged on a large diameter of the inner cone hole separately, and abutted against the inner wall of the inner cone hole; an annular elastic brake shoe is connected to the outer circle surface of theelastic push rod; an intake channel is formed in the brake body; a signal-controlled servo cylinder is connected to one end of the intake channel; an airtight piston cavity communicates to the otherend of the intake channel; a piston is arranged in the piston cavity; and the piston is connected with a column rod. The pneumatic brake on the hoisting machine aims at solving the problems of large occupied space, many parts and high repair cost of an additional pneumatic brake on an existing hoisting machine.
