Description

Technical Field

[0001] The utility model relates to the technical field of container reach stackers, and specifically discloses a container reach stacker sling. Background Art

[0002] Container reach stacker, commonly known as "container reach stacker", is a highly flexible container stacking and handling machine. It is equipped with a telescopic and pitching boom on a self-propelled tire chassis and a special spreader for international standard containers that can be telescopic and rotating. The boom can be telescopic, pitched and the spreader can be rotated while the vehicle is loaded and moving.

[0003] The container reach crane of the prior art, such as the patent with announcement number CN219009664U, discloses a container reach crane, including a body, an upper disc is fixedly installed at the bottom of the body, and a lower disc is movably connected to the bottom of the upper disc. The utility model sets a first lock, a first gear and a second gear. When the first lock passes through the waist-shaped hole and extends to the outside of the lower disc, the first gear will be driven to rotate through the rotating rod due to the operation of the brake motor, and then the second gear will drive multiple first gears to rotate synchronously, so that the first gear will drive the first lock to rotate ninety degrees through the connecting rod, and then the top of the first lock will be movably connected to the bottom of the lower disc.

[0004] In the above scheme, the upper disc and the lower disc are movably connected to facilitate the rotation of the spreader. However, the two discs need to be connected all the time during operation. When lifting containers on a higher floor, the crane needs to be moved to repeatedly adjust the angle and position of the entire container reach spreader to align the container, which makes the operation inconvenient and affects the lifting efficiency. Utility Model Content
