ABSTRACT:
The present invention makes it possible to increase the inner width between left and right main frames without increasing the entire width of a vehicle, to reduce the weight, and to improve the productivity. For this purpose, in a main frame structure for construction equipment including a pair of left and right main frames, a cross member connecting the front portions of the pair of left and right main frames and vertically swingably supporting an equalizer bar for coupling a pair of left and right track frames, and lift cylinder supporting elements rotatably supporting one end of a lift cylinder for raising and lowering a working machine frame mounted with a working machine, the pair of left and right main frames (1a, 1b) are respectively composed of a straight plate provided along a longitudinal direction of a vehicle body, and each of the lift cylinder supporting elements is integrally fixed on the outside in a lateral direction of the vehicle body, of the pair of left and right main frames (1a, 1b).
