[0003] The existing base body design structure does not fully utilize the high-strength box-shaped structural characteristics of the base body itself. When the vertical legs need a large travel support, the base body width is reduced and the vertical legs are exposed to the sides of the base, resulting in a shortened overlap length of the horizontal telescopic legs, affecting the support safety of the leg box; or the telescopic stroke of the horizontal leg box is shortened, shortening the leg span, ultimately affecting the support stability and the lifting performance of the crane. Utility Model Content

[0006] A further improvement is that a sealing plate matching the mounting groove is provided at the outer end of the partition.

[0007] A further improvement is that the outer end of the partition is flush with the outer end of the mounting groove, the upper end of the sealing plate is connected to the mounting groove, and the lower end of the sealing plate is connected to the partition.

[0009] A further improvement is that the upper end of the vertical oil cylinder exceeds the upper end surface of the second telescopic leg.

[0010] A further improvement is that: the outer end of the first telescopic leg is provided with a receiving seat adapted to the upper end of the vertical cylinder; when the telescopic leg mechanism is fully retracted, the receiving seat is embedded in the corresponding storage space, and the upper end of the vertical cylinder is embedded in the corresponding receiving seat.

[0011] A further improvement is that the two ends of the fixed leg box are respectively flush with the two ends of the installation groove.
