Part Two of the crane's rear support legs.

Abstract

【Item Uses】 This design relates to the rear support legs of a crane, used for reinforcing support of the crane. 【Design Description】 This design consists of a cylindrical sleeve, a sleeve back plate, and support feet for the rear support frame of a crane. The cylindrical sleeve's rear back plate is connected to the interior of both sides of the rear of the crane's main beam. The support feet are placed inside the cylindrical sleeve, and the bottom of the support feet has a circular base. From the front view, the cylindrical sleeve support feet are located inside the main beam of the crane on both sides. The two cylindrical sleeves are symmetrically arranged on the left and right, and the sleeve back plate behind them is T-shaped and connected to the inner side of the main beam of the crane. Viewed from the rear, the rear of the crane's main beam has a flat outline, with cylindrical sleeve support feet located inside the main beam on both sides. Viewed from the right side, the cylindrical sleeve is vertically installed inside the main beam of the crane, and its relative position to the main beam of the crane can be clearly identified from the side. Viewed from the left side, its appearance corresponds to that of the right side. The cylindrical sleeve is located inside the main beam of the crane, and its side appearance and relative position to the main beam of the crane can be clearly identified from the left side. From the top view, the rear of the crane main beam forms a concave arc shape, and the cylindrical sleeve support foot is located inside the concave arc shape at the rear end of the crane main beam and is positioned close to the rear end. Viewed from below, the rear of the crane's main beam has a concave arc shape, with support legs positioned close to the rear end. As seen in the usage reference diagram, the cylindrical sleeve, back plate, and support feet are placed on the inner side of the rearmost part of the crane's main beam, relative to both sides, achieving a sense of aesthetic symmetry and balance. The "crane main beam" and "tires" covered in blue in the diagram are parts that this design does not advocate. In conclusion, although the entire design consists of rigid objects, it is composed of beautiful lines that possess the characteristics of strength and resilience, forming a unique and original appearance. It has indeed provided a distinct and different appearance design that has not been seen in the market or publications before the application. Therefore, a design patent application is hereby filed in accordance with the law.
