The invention discloses a wide-angle direct vision window for a cab of an overhead and gantry crane. The wide-angle direct vision window for the cab of the overhead and gantry crane comprises a main body frame, a left vision window and a right vision window which are arranged at the left side and the right side of the main body frame, and a door arranged on one side surface of the main body frame, and the cab is also internally provided with an adjustable shock absorption seat. The wide-angle direct vision window for the cab of the overhead and gantry crane is characterized in that a front vision window is connected between the left vision window and the right vision window and is cylindrically curved glass, one side, back to the interior of the cab, of the front vision window is a convex side, and the connecting ends of the left and right vision windows and the front vision window are arcs matched with the convex side; auxiliary sight glasses are also arranged at the two sides of each of the left vision window and the right vision window, are fixed on a sun shade at the upper end of the main body frame, and are fixed at positions 1/3L-1/2L away from the highest point of the convex side of the front vision window, and L is horizontal maximum width of the left vision window and the right vision window. By virtue of coordination of the front vision window and the auxiliary sight glasses which are made of cylindrically curved glass, a wide angle of vision of the cab during driving is realized, and the wide-angle direct vision window for the cab of the overhead and gantry crane has the advantages of simple structure, high practicability and the like.
