Description

Technical Field

[0001] The utility model relates to the field of cargo transportation, in particular to a hanging rack. Background Art

[0002] Large public buildings with central air conditioning built in the 1990s need to renovate their computer rooms due to outdated equipment and high energy consumption. Some of them have already been renovated. The main air conditioning room is generally located in the basement. The equipment is large in size and heavy in weight. The equipment lifting holes were closed during construction, making it very difficult for new equipment to enter the computer room.

[0003] The utility model with publication number CN213326369U discloses a hoisting frame, which relates to the field of cargo transportation, and includes a crossbeam and a connecting beam. At least two hanging points are arranged on the crossbeam. Both ends of the crossbeam are connected with columns. The columns include a first column and a second column. The first column and the second column at the same end of the crossbeam are arranged at an angle. The bottoms of the first column and the second column are provided with a sliding structure. The connecting beam connects the first column and the second column at the same end of the crossbeam.

[0004] The above technical solution realizes lifting by setting lifting points and connecting hand winches in series, and uses a lifting frame to lift a single steel structure, which reduces labor intensity and improves work efficiency. The construction efficiency is high and it is safe and reliable. However, the hand winch method is inevitably labor-intensive when transporting large goods. In addition, the lifting frame requires on-site welding, which will cause noise pollution. The fixed height of the lifting frame cannot adapt to different high and low sites. At the same time, the single-beam structure of the lifting frame will inevitably cause the problem of beam bending in terms of load-bearing during long-term use. Utility Model Content

In addition, the lifting frame needs to be welded on site, which will cause noise pollution, and the weight after welding is too high to be moved, and the transportation problem in low space cannot be solved. At the same time, the single-beam structure of this lifting frame is also inevitably prone to bending of the beam in terms of load-bearing during long-term use.
