Abstract

This item is a portable fall prevention device for preventing falls of manholes and people or objects at manhole construction sites. As shown in the reference oblique view showing the usage state, this item is moved over a manhole and fixed to the entrance of the manhole for use. As shown in the oblique view of the disassembled state of each part, this item can be disassembled and assembled as shown in the oblique view of the folded state of each part. The casters shown in the reference oblique view showing the names of each part make it easy to move around the site. In addition, the manhole can be supported by four fixing points shown in the reference oblique view showing the names of each part, so it is possible to prevent falling into the manhole during manhole work at construction sites. The safety belt hook shown in the reference oblique view showing the names of each part can be used to hang protective equipment for fall prevention.
