The invention discloses a novel cargo boom. The novel cargo boom comprises a base; a fixed seat is fixedly installed on the left side of the upper end of the base; a fixing shaft III is fixedly installed in the middle of the upper side in the fixed seat; the middle of the fixing shaft III is provided with an outer ring in a sleeved mode; rotary discs I are symmetrically and fixedly installed at the left end and the right end of the outer ring; limiting slots II are arranged at the middles of one sides, close to the outer sides, of the rotary discs I; a plurality of limiting blocks II are fixedly installed on the inner ring walls of the limiting slots II; the left end and the right end of the fixing shaft III are symmetrically provided with rotary discs II in a sleeved mode; a plurality oflimiting blocks I are fixedly installed on the two ring sides of the rotary discs II; and the limiting blocks I and the limiting blocks II are connected in a staggered and clamped mode; the rotary discs II and the limiting slots II are correspondingly arranged; a plurality of hydraulic cylinders II are annually arranged on one end faces of the outer sides of the rotary discs II; the other ends ofthe hydraulic cylinders II are fixedly installed on the fixed seat; a telescopic long arm is fixedly installed at the front end of the outer ring; and a fixing shaft I is fixedly installed in the middle of the front end of the telescopic long arm. When in use, a whole amplitude-change pole is pulled by using a motor, and the oblique angle amplitude is changed, so that pitching swing is carried out, and the usability is improved.
