とを特徴とする吊上げ物の落下防止装置。In a device that lifts a lifted object using a hoist supported by an upper support part, a cylinder device is provided in parallel with the hoist and whose upper and lower ends are connected to the upper support part and the lifted object, and a cylinder device is installed in the lifting system. A tension detector is installed to detect the presence or absence of tension in the hoist's lifting wire.
Furthermore, when the tension detector detects a tension state, the working chamber of the cylinder device is communicated with the atmosphere, and when a no-tension state is detected, the working chamber of the cylinder device is communicated with a pressure source to prevent the lifted object from falling. A device for preventing the fall of a lifted object, characterized by being equipped with a valve.
