Description

【Technical field】

[0001] The invention relates to a working equipment, more specifically a single arm portal crane. 【Background technique】

[0002] The single-arm portal crane is a typical loading and unloading equipment for the port's general wharf. The existing single-arm portal crane's jib support point is set on the turntable. In order to meet the lifting height requirements, the turntable and the mechanism set on the turntable must be With the rise of the metal structure, this leads to the rise of the center of gravity of the single-arm portal crane, which affects the rationality of the metal structure of the crane and the overall stability of the crane. At the same time, the herringbone frame structure of the existing single-arm portal crane also limits the winding of the hoisting wire rope from the hoisting drum to the hoisting pulley block of the herringbone frame to pass through a reverse winding pulley, so that the hoisting wire rope Reverse bending occurs during ...
