What safety design feature do most modern overhead cranes have that is unfortunately not a characteristic of the human back?

Most modern overhead cranes are equipped with load-sensing systems that prevent the lifting of loads that exceed their rated capacity, enhancing safety by minimizing the risk of tipping or structural failure. Unlike these cranes, the human back lacks built-in load monitoring and automatic adjustment mechanisms to protect against injury from excessive weight or improper lifting techniques. This disparity highlights the importance of ergonomic practices in manual material handling to prevent back injuries.
