Description

TECHNICAL FIELD

[0001] The utility model relates to the positioning field of hoist, specifically, relates to a hoist automatic control operation positioning device. BACKGROUND

[0002] Accurate positioning can prevent collisions between the crane and surrounding buildings, equipment, and personnel. For example, in a narrow construction site or factory workshop, if the crane is not accurately positioned, its jib may collide with walls, pipes, or other equipment, causing serious damage and even safety accidents. In port operations, positioning errors of large cranes may lead to collisions with adjacent cranes or ships, endangering personnel lives and property safety. For lifting heavy objects, accurate positioning can ensure that the heavy objects are placed in the predetermined safe position, avoiding dangerous situations such as tilting and sliding of the heavy objects due to improper placement. For example, on a construction site, accurately placing prefabricated components in the designated position is crucial for the structural stability of the building.
