Safe and stable lifting platform for constructional engineering

The utility model relates to the technical field of constructional engineering. The utility model relates to a lifting platform, in particular to a safe and stable constructional engineering lifting platform. Platform body, vertical supporting rods are arranged on the platform body along the edge of the platform body by a circle. Turntables are rotationally fixed on the supporting rods on the twosides respectively; turntable facing inward, a guide block is arranged on the surface of the turntable; a through hole is formed in the middle of the guide block; a fixed seat is arranged on the supporting rod; a slidable positioning column is inserted into the fixed seat; adjusting rods are in sliding fit with the inner sides of the guide blocks arranged on the turntables on the two sides; the top ends of the adjusting rods located on the two sides are in butt joint and fixed through a supporting handrail. The lifting platform solves the problems that the position of the handrail fixedly arranged on the lifting platf
