The invention discloses an emergency manual slow-descenting device and lifting equipment thereof. The emergency manual slow-descenting device comprises a speed change mechanism, a clutch mechanism anda slow-descenting mechanism, wherein the clutch mechanism is connected to the output end of the speed change mechanism through a high-speed shaft; the clutch mechanism is connected to the input end of the slow-descenting mechanism through an input shaft; the slow-descenting mechanism comprises a shell and a rotor, and the rotor is arranged in the shell and is connected with the input shaft; and the input shaft can freely rotate in the shell through a bearing arranged in the shell; and the rotor is provided with a first blade, and damping liquid is placed in the shell. Through the cooperativeaction of the speed change structure, the clutch mechanism and the slow-descenting mechanism, and the emergency manual slow-descenting device can be fully applicable to the low-speed, medium-speed andhigh-speed lifting equipment and enables the emergency slow-descenting of the lifting equipment to have the advantages of high efficiency, safety, stability, low noise, abrasion resistance and low maintenance cost.
