How does the built-in hydraulic safety relief system work in the Multiquip EM120HYD, and what specific scenarios is it designed to handle?

The built-in hydraulic safety relief system in the Multiquip EM120HYD is designed to automatically disengage the mixer's drive if an obstruction is detected or if the drum experiences excessive resistance. This system is crucial for preventing damage to the hydraulic drive and motor, and for protecting operators from potential injuries caused by overloading the mixer. It is particularly effective in scenarios where unexpected materials or debris become lodged in the drum.
