Prefabricated Beam Hoisting Video

Currently, we cannot directly provide a video of the hoisting of prefabricated beams for houses, but we can recommend relevant video resources and introduce the core hoisting process. Here is the specific information:

Recommended Video Resources

1. "Full Process Demonstration of Prefabricated Component Hoisting and Construction Techniques": This video covers the entire process of prefabricated components from transportation, lifting, to installation, including key aspects of prefabricated beam hoisting such as lifting point selection and lifting angle control, suitable for systematic learning of hoisting techniques.
2. "Prefabricated Beam Hoisting in Assembly Construction - Surveying, Setting Out, and Component Lifting": Focusing on the surveying, setting out, and component lifting stages, this video details how to determine the installation position of the beam using tools like laser levels, as well as the fixing method of steel wires during lifting, emphasizing precision control.
3. "Animation of Prefabricated Component Hoisting in Assembly Concrete Structures": This video simulates the hoisting process in 3D animation, visually presenting the dynamic changes of the beam from a horizontal to a vertical installation state, helping to understand the collaborative operation logic of hoisting machinery (such as tower cranes).
4. "Prefabricated Composite Beam Hoisting Construction Process in PC Installation Training for Assembly Construction": Focusing on the hoisting of composite beams (a type of prefabricated beam), this video breaks down the construction steps, including the erection of temporary supports and fine-tuning of the beam after positioning, suitable for on-site operators as a reference.

Core Process of Prefabricated Beam Hoisting

1. Preliminary Preparation: Check the load-bearing capacity of hoisting equipment (such as tower cranes and steel wires), confirm that the beam strength meets design requirements; clear debris from the installation site and survey and set out to determine the beam axis position.
2. Component Lifting: Use dedicated lifting fixtures to secure the lifting points at both ends of the beam, maintain a constant speed during lifting, and avoid sudden stops or turns; pause after the beam leaves the ground to check the stability of the lifting fixture connections.
3. Positioning and Installation: Move the beam to above the installation position through the luffing and slewing actions of the tower crane, slowly lower it to about 50cm above the installation surface and pause, then manually assist in fine-tuning the beam axis to align with the set-out position.
4. Fixed Connection: Immediately install temporary supports after the beam is in position to prevent overturning; then proceed with steel bar tying, formwork support, and finally pour concrete at the joints to complete the permanent connection.

Safety Precautions
Set up warning lines in the hoisting area to prohibit non-operators from entering; suspend operations in winds of force six or above or during rain and snow; operators must be certified and strictly adhere to equipment operation procedures.
