The present application relates to the technical field of linkage mechanisms, and provides a linkage operation assembly, a fall protection device and a fall protection system. The linkage operation assembly includes a fixed main body configured to be installed on an outer support surface of a rail and move along the rail; a second wheel body assembly installed on the fixed main body for rolling along an inner support surface of the rail and including a second wheel set and a drive rotary shaft; a third wheel body assembly installed on the fixed main body for rolling along an inner support surface of the rail and including a third wheel set and a driven rotary shaft; and a linkage member disposed between the drive rotary shaft and the driven rotary shaft. When the drive rotary shaft of the linkage operating assembly rotates, the second wheel set is driven to rotate, and the driven rotary shaft and the third wheel set are driven to rotate through the linkage member. Therefore, during the installation process of the linkage operation assembly, only the drive rotary shaft needs to be rotated to switch the state of the linkage operation assembly, so as to facilitate the installation of the linkage operation assembly. Similarly, when the linkage operation assembly is disassembled, only the drive rotary shaft needs to be rotated.
