Embodiment Construction

[0024] Fig. 1 is the overall structure schematic diagram of double 40 feet storage yard gantry crane of the present invention. Please first refer to shown in FIG. 1 , the double 40-foot stockyard gantry crane of the present invention includes a gantry 10 and a running trolley 20 located on the gantry 10 . The following gantry 10 is equipped with running mechanism, which can walk in the storage yard. The running trolley 20 can run on the gantry 10 . On the running trolley 20, there are two sets of hoisting mechanisms 30a, 30b, two sets of wire rope winding systems 40a, 40b, and two sets of spreader systems 50a, 50b. The structure of the gantry 10, the running trolley 20, the single hoisting mechanism 30a or 30b, the single set of wire rope winding system 40a or 40b, and the single spreader system 50a or 50b is similar to the structure of the yard gantry crane that can lift a single 40-foot container. substantially the same, so its specific composition is not the focus of the ...

Abstract

The invention discloses a double 40 inches yard gantry crane including the gantry frame and a move dolly set on the gantry crane. The crane includes two sets of the hoisting mechanism, two sets of the steel rope enwinding system and two sets of hanger system; the hoisting mechanism is set on the move dolly which is set with a set of steel rope enwinding system. The steel rope is leaded from the hoisting mechanism and enwinds on the rope enwinding system which the rope cross with each other. A set of hanger system is hanged under the enwinding system which includes up frame and a hanger. The left-right move oil cylinder is set at the bottom of the each up frame and the front-back oil cylinder is set at both sides of the up frame. The hanger is set under the up frame and driven by the left-right move oil cylinder to move to right or left, also the same as the front-back oil cylinder. The two up frames are connected by the oil cylinder to reach the relative separation and combination.

Description

technical field [0001] The invention relates to a hoisting machine, in particular to a yard gantry crane capable of hoisting double 40-foot containers. Background technique [0002] With the increase in size of container ships, container cranes are also developing towards high efficiency. In many ports around the world, shore-to-shore container cranes that can lift two 40-foot containers have appeared, and the efficiency of cutting-edge equipment has doubled. However, for a long time, the gantry crane in the yard can only lift one 40-foot container at a time, and the low efficiency of the gantry crane in the yard has become a bottleneck restricting the improvement of terminal productivity. Compared with shoreside container cranes, yard gantry cranes have more stringent requirements on the relative position coordination of simultaneous operation of multiple containers due to the limited space of container stacking on the site, and also put forward special requirements on the ...
