Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cranes, in particular to a marine hydraulic crane. Background Art

[0002] A crane refers to a multi-action lifting machinery that can vertically lift and horizontally move heavy objects within a certain range. It is also called an overhead crane, an overhead crane, or a hoist. Currently, in the process of loading and unloading goods in some warehouses, in addition to forklifts, a small crane is often required. The objects moved by cranes are generally heavier, which requires the mounting frame at the bottom of the crane to have sufficient counterweight to maintain the stability of the crane when in use.

[0003] In order to solve the counterweight problem when the crane is lifting, the current mounting frame generally installs a counterweight block on the mounting frame. However, when the counterweight on the mounting frame needs to be adjusted, the counterweight block is often simply added to the original counterweight block on the mounting frame. However, after the counterweight block is added, there is a lack of fixing measures for the subsequently added counterweight block, which may cause the counterweight block to slide if the cargo accidentally collides with the counterweight block, which is very likely to cause a safety accident, greatly reducing the safety of the crane when in use. Therefore, a marine hydraulic crane is proposed to solve the above problem. Utility Model Content
