Anti-swinging mechanism for lifting sling of crane

Abstract

The invention discloses an anti-swing mechanism for a crane spreader, which includes a lifting mechanism, a fixed pulley block and a movable pulley block, each trolley is provided with a lifting mechanism, the reel is placed in the center of the trolley, and the center of the trolley frame is placed with a The fixed pulley block, the trolley running mechanism is placed at one end of the trolley frame, and the lifting mechanism is distributed on the four corners of the trolley frame plane. A movable pulley block is installed in the center of the spreader, and the four corners of the spreader are fixed with wire ropes. Ears, the four sides on the back of the sling are provided with hooks for the object to be hoisted, and a steel wire rope is thrown off from the reel on the lifting mechanism respectively, and fixed by the four lifting eyes on the sling body. The invention solves the problem that the crane can effectively prevent the spreader from swinging back and forth only when the crane is running or the trolley is started and stopped. The mechanism has simple structure, low cost and is easy to manufacture.

Description

Technical field: [0001] The invention relates to an anti-sway mechanism on a crane, which is especially suitable for use when hoisting containers. Background technique: [0002] When the crane starts or brakes, due to the inertia of the heavy objects, the spreader under the crane always swings back and forth for a long time before stopping after the crane stops. Even more than a dozen layers of containers are neatly stacked together. If the container spreader swings when the crane brakes, it will be difficult for the driver to complete the lifting, and the work efficiency is very low. Invention content: [0003] The task of the present invention is to propose a anti-swing mechanism of a crane spreader with a simple structure in which the dustproof spreader swings back and forth during the lifting project. [0004] The task of the present invention is accomplished in this way. The anti-swing mechanism of the crane spreader includes a lifting mechanism, a fixed pulley block...
