Description

Side double box empty box spreader

technical field

The utility model relates to crane technology, more specifically, relates to a crane spreader.

Background technique

At present, the traditional loading and unloading method of the quay container crane, also known as the spreader on the quay bridge, is: from the top of the container, connect with four corner pieces on the top surface of the container through four revolving pins to lift the container.

Affected by the large-scale ships, the height of the ships is getting higher and higher, and the height of the containers stacked on the ships is also getting higher and higher. Some quay bridges purchased in the early days of the port, due to insufficient lifting height, float on the ship during the high tide. Later, the height difference between the main beam of the crane and the crane became smaller, and the traditional spreader could not load and unload the container from the top of the container and stack it on the top container of the ship.

Due to the high price and complicated process of purchasing a new quay crane or rebuilding the quay crane, it is a reasonable choice to change the lifting method of the spreader. From the law of container stacking, basically empty containers are stacked on the high area or on the top, and the empty containers are light in weight, so they can be lifted from the side. When lifting the container from the side, the spreader does not need to be lifted higher than the height of the container, so the requirement for the height of the crane can be reduced, and the existing quay bridge can also meet the demand. Among the existing products, there are side empty container spreaders with two lifting points or four lifting points, which can lift empty containers from the side. However, these existing products can only lift one empty container at a time, and the operation efficiency is relatively low. The double-container truck needs to wait for two operations on the track to remove the two empty containers.
