The invention discloses a crane gooseneck boom. The crane gooseneck boom comprises a pulley, side plates, a connection plate, connection pieces, a vertical plate and ear plates for connecting a jib arm support; the pulley is connected to the side plates in a rotating manner through a connecting body; the side plates are fixedly connected to one surface of the connection plate, the first end of each connection piece is fixedly connected with the connection plate, and the second end of each connection piece is fixedly connected with the vertical plate; the ear plates are connected to the vertical plate. By adopting the crane gooseneck boom, the way for bending an entire plate in the prior art is changed, and components are gradually connected one by one, so that the bending and the correction are avoided, the directness in positioning and connection is realized, the simplicity and the convenience can be realized, the problem the bending is difficult in the prior art that can be solved, the connection strength, the stability and the accuracy in installation are relatively high, the size is small, and the weight is light. The invention also provides a crane comprising the crane gooseneck boom. The gooseneck boom of the crane is prone to install, stable in structure and light in weight, and the quality of the crane is improved.
