Abstract

The invention which discloses a semi-traction dolly type light-weight portal crane aims to provide a fixed or rubber-tyred or rail-mounted lifting loading and unloading apparatus with the advantages of simple structure, light weight, and economy and utility. The crane comprises a hoisting mechanism arranged at the bottom platform of a frame, a dolly frame and a dolly operation mechanism arranged on the kingpost track of the frame, a suspender connected with the dolly frame through first, second, third and fourth wire ropes, and a suspender rotary tilting device arranged at the rear side of the frame, wherein first ends of the first to fourth wire ropes are respectively connected to the reel of the hoisting mechanism; and second ends of the first to fourth wire ropes, which respectively slidingly go through the frame, the dolly and the assembly pulley of the suspender, are respectively connected to both ends of the suspender rotary tilting device or directly fixed on the wire rope fixing end at the rear side of the frame. The portal crane has the characteristics of light weight, saved investment, low energy consumption, low wheel pressure, low maintenance and use cost, and the like.

Description

technical field [0001] The invention relates to a lifting and transporting machine, in particular to a semi-drawing trolley-type light gantry crane for loading and unloading containers. Background technique [0002] In recent years, with the expansion of my country's foreign trade, the container transportation industry has developed rapidly, and at the same time it has driven the technological progress and rapid development of container handling equipment. Compared with various cranes used in other industries, port cranes have high operating efficiency and generally high energy consumption. Therefore, it is of great significance to realize energy saving and emission reduction of container handling equipment. With the continuous increase of energy prices and the deepening of energy conservation and emission reduction policies, the lightness and economy of container handling equipment will surely become a new development trend. [0003] Traditional tire-type container gantry ...
