How to Lift Prefabricated Panel Houses

The methods for lifting prefabricated panel houses mainly include manual lifting, using floor slab trolleys, and special methods (such as lifting with two wooden sticks), etc. The specific operations and precautions are as follows:

Manual Lifting: This is a relatively common method that relies entirely on human strength. Usually, four people work in pairs to lift and move the floor slab. When carrying, the number of people should be determined according to the thickness and weight of the slab. For a whole slab with a thickness of 10 - 20 millimeters, four people are generally required, while for a whole slab with a thickness of 25 - 30 millimeters, six people need to work together. At the same time, the correct lifting posture should be adopted. Place your feet on both sides of the cover plate, shoulder-width apart. Keep your back straight when bending over, rely on the strength of your legs to squat up, and lift the cover plate close to your body's center of gravity to reduce the risk of back injury.

Using Floor Slab Trolleys: This method requires first lifting the floor slab manually and then hooking it onto the hooks under the two outstretched fixed arms of the trolley. After that, push the trolley to move the floor slab away. This method combines the advantages of human strength and tools, which can reduce the human burden to a certain extent and improve handling efficiency.

Special Methods (such as Lifting with Two Wooden Sticks): There are cases where four people lift a prefabricated panel with two wooden sticks. However, the specific operation details are not described in detail. Caution should be exercised when trying this method in practice to ensure safety.

Before lifting the prefabricated panel, sufficient preparations should be made. First, clarify the information about the cover plate, measure its length, width, and thickness, and estimate its weight to arrange the manpower reasonably and select appropriate tools. Second, survey the handling path, measure the entire path, conduct a "three-dimensional rehearsal", and identify and solve potential problems in advance. Also, prepare auxiliary tools such as crowbars, rollers, ropes, lifting bars, or special lifting straps. During the lifting process, assign roles and positions to the personnel. Designate a commander to give orders and observe the overall situation, coordinate the lifting and moving, and keep in step to avoid accidents caused by uncoordinated movements. After reaching the predetermined position, place the prefabricated panel steadily and check the tools and on-site risks to ensure the safety of subsequent work.
