Description

Technical Field

[0001] This invention belongs to the field of lifesaving technology, specifically relating to a hand-cranked tank-borne wounded rescue hoist. Background Technology

[0002] Tanks, as assault weapons combining offensive and defensive capabilities, have a significant impact on the course and outcome of wars. Their crucial role in warfare makes them a key target in modern warfare, especially high-tech local conflicts. Tank crew members face a high-risk profession; once trapped in an airtight armored vehicle, death can be instantaneous. Rescuing wounded personnel inside tanks is vital to their survival. However, due to the complexities of the battlefield environment, current tank crew rescue primarily relies on self-rescue and mutual aid. Wounded personnel are often pulled out of the tank by rescuers. This method has the following drawbacks: ① Rescuing wounded personnel requires one person to enter the tank to assist while another rescuer remains outside. The confined space inside the tank makes it difficult to gain leverage, leading to difficult and inefficient rescues. ② Wounded personnel inside tanks often suffer injuries to the torso and spine. In the confined space, the pulling process can easily cause secondary injuries. Summary of the Invention

[0003] Purpose of the invention: To address the difficulties in rescuing wounded soldiers inside tanks on the battlefield, the current method primarily relies on rescuers manually lifting them out of the tank, resulting in low rescue efficiency and the risk of secondary injury during manual rescue. This invention provides a hand-cranked tank-borne wounded soldier rescue lifting device, which features reliable fixation to the tank, rapid deployment, stable and reliable lifting, and convenient installation.
