A lifting appliance enabling brick stacks to be combined and rotated in air comprises a main body support, guide rail beams, walking mechanisms, lifting arms, guide rail pulleys, a cross beam, rotating clamp moving mechanisms, a drive motor, a drive gear, wheels, a steam-curing cart, rotary clamping frames, rotating assemblies, rotating hydraulic motors, lifting moving carts, a lifting hydraulic cylinder, moving hydraulic cylinders and stand columns. The walking mechanisms are arranged on the two sides of the main body support, the lifting arms are connected with the corresponding guide rail beams, the two ends of the cross beam are fixed at the lower ends of the corresponding lifting arms, the drive motor, the lifting hydraulic cylinder and a pair of lifting moving carts are arranged on the main body support, the lifting hydraulic cylinder is located on one side of the lifting moving carts, a pair of rotating clamp moving mechanisms is arranged on the cross beam, and the upper ends of the rotating clamp moving mechanisms are connected with the lifting arms through the moving hydraulic cylinders. Aerated bricks are moved and packaged by combining and rotating aerated brick stacks in air, and the aerated bricks can be clamped well and moved to be placed on pallets which need to be packaged. The aerated bricks can be rotated by 90 degrees, operation is simple, and work efficiency is high.
