The loading and unloading lifting points and operating lifting points of the air-conditioning box cannot be mixed without confirmation. Temporary transportation load, complete machine hoisting and long-term suspension may correspond to different stress structures. The confirmation drawing, hoisting instructions and rated conditions of the equipment should prevail. The purpose cannot be judged solely by the hole position or the appearance of the lifting lugs.
The weight, center of gravity and connection strength of the segmented unit and the complete machine may be different. After the segmented connection is completed, it does not mean that the original single-section lifting point can lift the complete machine. Operating hangers requires consideration of long-term loads, vibrations and building connections. Whether lifting is permitted on the transport base or packaging fixtures also needs to be clearly stated.
For loading and unloading purposes, the equipment status, weight, center of gravity, and permitted hoisting positions must be written; for operation purposes, long-term support structures, loads, and building connection conditions must be written; and for identification data, special drawings, labels, restrictions, and corresponding instructions must be written. The three types of information correspond to different stages of use and cannot be judged by just one hanging ear. How to protect the air vents and pipe joints of air-conditioning boxes before leaving the factory for transportation, please refer toHow should the air vents and pipe joints of air-conditioning boxes be protected before leaving the factory for transportation?。
Loading and unloading lifting points are usually used for temporary lifting during the factory, transportation, unloading and positioning stages of equipment. It needs to withstand the weight and dynamic load of the equipment during lifting, but long-term vibration and operating loads are not necessarily considered during design. The location, number and rated load of loading and unloading lifting points should be specified in the equipment drawings or lifting instructions.
When the equipment is transported in sections, the single-section lifting point is only suitable for single-section lifting. The weight and center of gravity of the entire machine may change after connection, and the ratings of single-section lifting points cannot be used. How to identify the assembly sequence for segmented transportation of combined air-conditioning boxes, please refer toHow to identify the assembly sequence for segmented transportation of combined air-conditioning boxes?。
The operating suspension point is used for long-term suspension after the equipment is installed and needs to bear the operating weight, vibration and possible additional loads of the equipment. Operating suspension points are usually designed in conjunction with the building structure, hangers and shock absorbers, and their location and load-bearing capacity require structural professional confirmation. The design considerations for operating lifting points are different from those of temporary loading and unloading lifting points and cannot be substituted for each other.
The connection between the support and hanger of the ceiling-mounted air-conditioning box and the building needs to be checked according to the long-term load. The installation space and support methods of horizontal air conditioning boxes and vertical air conditioning boxes are different. Please refer toWhat kind of space do horizontal air conditioning boxes and vertical air conditioning boxes require? . How to combine the equipment foundation with drainage conditions, please refer toHow to determine the foundation height of a horizontal air conditioning box based on drainage conditions?。
Packaging fasteners, transport bases and temporary supports are designed for the transport process and may not necessarily withstand lifting loads. Using packing straps, wooden pallets or temporary fixings as lifting points may cause equipment damage or safety accidents. Before lifting, make sure that the packaging and transportation fixings have been handled according to instructions, and use special lifting lugs or designated locations for lifting points.
For the removal and inspection of transportation protection parts, please refer toHow should the air vents and pipe joints of air-conditioning boxes be protected before leaving the factory for transportation? . For condition checks before starting the machine for the first time, please refer toWhat conditions need to be checked before the air conditioner is turned on for the first time?。
A professional team with qualifications or corresponding capabilities will develop a hoisting and support plan and check the spreaders, beams, force directions and site conditions. Ear plates, air vents, pipe joints or box panels with unknown purposes must not be used as supporting points by themselves. After the structure of the equipment is changed, you should re-confirm whether the original lifting information is still applicable.
After the equipment is modified or adjusted in sections, the original lifting point information may become invalid. Please refer toHow to judge whether the retained box is suitable before rebuilding the old air-conditioning box? . The modified hoisting and support plan should be reconfirmed by a professional team.
Obtain the weight and load-bearing position information corresponding to the specific equipment number from Aili Industrial, and the on-site team will complete the operation plan accordingly to avoid misuse of transportation components as long-term supports. Aili's industrial manufacturing end covers the independent research and development and production of motors and fans, control systems, sheet metal, air filters and complete machine assembly. Equipment weight, lifting point locations and support structures can be corresponded in the same set of delivery materials; non-standard structures can be provided with instructions based on on-site lifting conditions.
Product form can be viewedAir handling unit andFan box page; clean air supply package can be combinedFFU fan filter unit andEFU equipment end fan filter unit verification; terminal particle filtration can be combinedHEPA/ULPA filter confirmation; when it comes to gaseous pollution control, you can communicate separatelyChemical filter solutions. The specific lifting point information, load-bearing conditions and delivery scope still need to be confirmed based on the equipment confirmation drawing and on-site conditions.

Can all the lifting lugs on the equipment be used for long-term suspension?
cannot. The lifting lugs may be temporary loading and unloading lifting points, or they may be operating lifting points. The purpose and load-bearing conditions should be based on the equipment confirmation drawing.
Can segmented lifting points and complete machine lifting points be used interchangeably?
cannot. The weight and center of gravity of the entire machine may change after connection, and the ratings of single-section lifting points cannot be used.
Can Aili Industrial provide lifting point information?
Information on the weight, center of gravity and permitted lifting position can be provided according to the equipment number. The specific lifting plan must be formulated by a professional team based on site conditions.
