Safety brake device for automatic reel with spring return

On ordinary spring-actuated automatic reels there is always a risk, when extended, of the rapid whip-back of the cable/wire/hose causing a “whiplash” effect dangerous for the equipment and any persons nearby. The most common cause of this hazard is the unintentional break of the connection between the cable/wire/hose and the consumer (tool) being moved (or the operator). With industrial reels in particular, the spring forces when extended are very high. Our invention counters this hazard with a reaction time of 1/10 second by applying the brake following accidental loss of the connection. After this, the cable/wire/hose is automatically rewound onto the reel at low speed. The “whiplash” effect is completely eliminated. Threat of risk to people and equipment is ruled out entirely.
