Application Background

A "plummeting" incident refers to the elevator car passing over the top section and plummeting towards the ceiling, in severe cases, it can even throw the entire car upwards and cause it to fall, leading to mass casualties. Such accidents are usually caused by the failure of the braking system, the upper limit switch or upper limit safety switch not functioning, or the elevator ascending at an excessive speed.

Solution

Install the HaiZhi construction lifting safety monitoring host with height sensors in the construction lifting machine. Set the lifting height parameters and risk height warning values through the host. The directional safety braking is initiated when the data from the height sensors reaches the warning risk value, preventing the occurrence of a collision with the ceiling.
