徴とする荷物昇降装置の安全装置。 Safety provided in a cargo lifting device in which a runner movable along a guide post erected on one side of the periphery of a cargo platform is connected to a drive source by a transmission wire, and a lifting platform supported by the runner is raised and lowered. In the device, the transmission wire includes, in addition to a main wire that raises and lowers the lifting platform, a sub wire that is wound in parallel around a sheave on which the main wire is hung, and the sub wire has a wire that is smaller than the main wire. At the same time, one end of the wire is fixed to the runner using a wire with a thin wire diameter.
The other end is fixed to the tip of a link rotatably connected to the upper part of the frame of the lifting device, and a spring is provided to bias the link tip to rotate upward, so that the main wire can be easily fixed when the main wire breaks, etc. A safety device for a cargo lifting device, characterized in that tension is applied to the sub wire to prevent the lifting platform from falling.
