Description

Top section arm for realizing installation of multiple gooseneck frames

Technical Field

The utility model relates to the technical field of crawler cranes, in particular to a top section arm for realizing the installation of a plurality of gooseneck frames.

Background

Crawler cranes are typically equipped with 2 hook heads. When the heavy objects with large tonnage are hung, the lifting capacity is high and the lifting speed is low. When the articles with smaller weight are hoisted, a small hook is usually selected to save hoisting time. While the mounting location of the small hooks is typically on the head rest of the top knuckle arm. The gooseneck boom of the crawler crane is a movable mountable part which is generally mounted when the use requirement is met.

The size of the goose head frame of the crawler crane is relatively close, and confusion is easy to occur during use and management, so that the problem that the goose head frame on the pulling-over site cannot be installed is solved. In order to avoid the occurrence of the above situation, a structure of the top joint arm is conceived, and the installation of the goose head frame with various specifications can be realized, so we propose a top joint arm for realizing the installation of a plurality of goose head frames.
