{wiki=Boom_brake}
A boom brake is a safety device commonly used in various types of machinery and equipment, particularly in cranes and other lifting devices. It is designed to prevent uncontrolled movements of the boom (the arm or extending part of a crane) in the event of a failure or emergency situation. The boom brake works by applying friction to the boom or its mechanisms, which helps to hold it in place and prevent it from falling or swinging uncontrollably.
