Step 4: Lift and debug the unloaded electric gondola, then complete the synchronous debugging of the telescopic hoisting system and the telescopic test of the boom 8; gradually load the electric gondola, and record each time the electric gondola adds goods The drop value and state of , complete the overall test;

Step 5: After Step 4 is completed, that is, a construction platform is built on the outer facade of the non-standard layer of the high-rise building. The construction platform can be stretched forward or backward through the boom 8 of the telescopic lifting system to realize construction. The distance between the platform and the building facade is adjusted to meet the construction requirements of the building's non-standard layer facade.

After the construction platform is completed, the lifting platform can be used. Taking the floor plane where the lifting platform is installed as an example, the driving gear 95 is driven by the driving motor 94, and then the boom 8 is driven by the driving gear 95, so that the boom 8 pulls the electric gondola back and forth along the long direction of the boom 8. Move, the distance between the electric gondola and the building facade can be adjusted, so that when a certain floor of a high-rise building protrudes from the overall building facade, the electric gondola can be adjusted through the boom 8 and the protruding outside such as a balcony , bosses or podium facades, etc. are adapted to the size. Under the condition that the lifting platform is not re-installed, the electric hanging basket can be used as the construction platform for the construction across the façade, which saves the construction process, time and cost. As for the suspended height of the electric hanging basket, it is completed by the electric hanging basket itself, so it will not be repeated in this case.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
