Not only cables and wires need to rely on transformers, but also transformers need to be installed in high-rise buildings. Excessive transformer losses can bring some safety hazards. In order to prevent this, a high-rise building needs to move the existing old transformer to another location and install a new one. However, the transformer is very large and cannot be easily transported by manpower alone.

After discussion, the relocation company that constructed the high-rise building decided to relocate the transformer at night. They carried necessary light and small lifting tools such as claw jacks, electric hoists, and manual hoists. After removing the outer shell and bottom anti mouse net of the transformer, they found the correct position below the transformer and used claw jacks to lift the large tonnage transformer. When the height of the transformer gradually increased, they also put in manual hydraulic handling tools to push the handling vehicle and move the transformer to the target position.

In terms of lifting transformers, claw jacks have an absolute advantage over screw jacks, hydraulic jacks, and other types of jack tools. Although the claw position of the jack is only half of the top bearing capacity, its bearing capacity is between 2.5 tons and 25 tons, and it is fully capable of lifting heavy objects such as transformers.
