The term crane warning system is a generic phrase used for any type of crane indicator. It could be used to describe an anti-two-block (ATB) system, crane load indicator, crane load moment indicator (LMI), rated capacity indicator (RCI), or any system in between.
Most customers searching for a crane warning system are interested in making their crane safer and easier to use, which makes the crane operations more efficient. Installing an ATB alarm system is an inexpensive addition that makes the crane operator's job safer and easier. The ATB alarm is cheap insurance against expensive boom damage, so it is usually the minimum operator aide added to every crane. The next most important thing most customers want to monitor is the amount of weight they are picking up. A simple load indicator will fill this role. It's very common on a construction site for a crane to be used to lift an object where the weight is unknown, and the operator is forced to guess if he is going to overload the crane. A load indicator combined with a competent operator who understands the crane's load charts can overcome this problem. The load indicator will give the operator a valuable tool to avoid a crane accident or damage to the crane. The best crane warning system is an LMI or RCI, depending on the best fit for the crane. These will show the crane operator all the important lifting-related data, including the weight, capacity, boom length, angle, radius, and ATB warning.
Crane warning systems are an essential operator aid for every crane today. Similar to all the safety advances in cars today, crane warning systems have come a long way and make older cranes safer and more efficient for the owners and operators. They will save you time and money, and for many jobs, they are required, which makes your crane more valuable when you have them installed.
