Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and in particular relates to a silent double-beam European crane. Background Art

[0002] European double-beam crane is a kind of heavy machinery equipment widely used in the industrial field. It is based on the European lightweight and modular design concept and advanced manufacturing technology. This type of crane usually includes a bridge frame, on which there is a trolley and a lifting mechanism. The trolley can move forward and backward, and the trolley is responsible for horizontal movement. Through the coordinated work of these mechanisms, the European double-beam crane can carry out material handling in three-dimensional space.

[0003] After searching, it is found that the existing Chinese patent with publication number CN217708596U discloses a suspended double-beam European crane, which relates to the technical field of cranes, specifically a suspended double-beam European crane, including a crossbeam and a buffer brake plate, a lifting trolley is arranged above the crossbeam, and a block is installed on the top of the lifting trolley.

[0004] Although the above-mentioned crane has the effect of improving the walking stability of the lifting trolley and preventing the lifting trolley from falling, the lifting trolley is suspended on the crossbeam, and is inserted into the inside of the slot through a card block. The limit rod limits the position of the card block. As the lifting trolley moves, the positioning slider can move along the length direction of the positioning slide slot, thereby improving the walking and installation stability of the lifting trolley, improving the safety of use, and achieving the purpose of improving practicality. However, when the above-mentioned crane is lifting, if there is a large friction between the connecting rope and the winding roller in the crane, it is easy to produce a large noise, thereby generating a lot of noise to the surrounding environment.
