Description

Technical Field

[0001] This application relates to the field of cage hoisting technology, and more specifically, to an assembled cage frame assembly for a construction hoist cage. Background Technology

[0002] As an indispensable vertical transportation equipment on construction sites, the cage of a construction hoist is a key component for carrying personnel and materials. The cage frame, as the main load-bearing structure, directly affects the safety and efficiency of the entire machine. Currently, construction hoist cage frames are generally manufactured using steel profiles (such as square steel and channel steel) through welding. While this traditional structure has the advantages of being sturdy and having high load-bearing capacity, it also has a series of significant drawbacks: The overall weight is large, making transportation inconvenient: Due to its all-steel structure and indivisible nature, the cage itself is extremely heavy. Transporting it to the construction site or moving it between different sites requires the space of large transport vehicles, and the hoisting and handling process is cumbersome and costly.

[0003] Non-removable, lacking versatility and flexibility: The welded cage frame is a permanent, rigid unit, making it impossible to flexibly adjust or change its structural dimensions according to actual construction needs (such as different shaft sizes or floor heights). Furthermore, this non-removable characteristic also prevents it from adapting to modern modular and standardized construction concepts.

[0004] Storage and maintenance difficulties: For construction companies, a large number of integrated cage frames require a huge amount of storage space. In addition, if a part of the cage frame (such as a single column or beam) deforms or is damaged during use, the entire cage frame often needs to be returned to the factory for large-scale cutting, repair and re-welding. The maintenance cycle is long, the cost is high, and it may even lead to the scrapping of the entire cage frame, which increases the quality risks and management costs of production and manufacturing.
