The invention discloses a width-adjustable forklift overhead guard which comprises a supporting leg assembly, a width adjusting assembly and a width adjusting assembly. The top protecting frame comprises two inverted U-shaped frame edge strips connected with the supporting leg assemblies, a centering connecting rod arranged between the two frame edge strips and a plurality of groups of movable rods; one end of the movable rod is hinged to the centering connecting rod, and the other end of the movable rod is hinged to the frame edge strip. The sliding mechanism is arranged at the joint of the supporting leg assembly and the frame edge strip; the sliding mechanism comprises rollers connected to the frame edge strips and sliding grooves connected to the supporting leg assemblies. The rollers slide back and forth in the sliding grooves in the vertical direction of the centering connecting rod in a limited mode. And the driving mechanism is used for driving the frame edge strips on the two sides to move back and forth close to each other or away from each other. The width of the overhead guard can be quickly adjusted through the driving mechanism and the sliding mechanism, a self-locking function is achieved, centering of the overhead guard can be achieved when the width is adjusted, and therefore the comfort and safety of a driver are guaranteed.
