Signaling is critical to maintaining safety in crane elevator applications

Audible and visual signals reduce the risk of dangerous and costly accidents.

June is #NationalSafetyMonth, an opportunity to raise awareness of the significant hazards to technicians, operators and other ground workers associated with the use of crane lifts. To avoid accidents, it is imperative that everyone nearby knows that a crane and its load are nearby.

Audible and visual signals help protect yourself from these dangers by notifying people under or near a moving load so that they can take the necessary precautions to avoid damage. Correct signals are therefore crucial; Inferior signals that are inaudible or not sufficiently visible in the workshop can lead to dangerous and costly accidents.

For an additional safety advantage, dual sounder and flash combination signaling devices are recommended, especially for bridge cranes. There are hardly any differences in cost between combination and single signal devices; however, the added value to the user is immense as operating conditions can prevent workers from hearing or seeing a signal, but rarely both.

Advantages of acoustic and visual signaling when using overhead cranes

Combined signaling devices in bridge crane environments can offer cost savings through two different options: reduced risk of personal injury and increased throughput in the factory floor. Signal devices reduce the risk for personnel by warning them of impending dangers so that there are no fatalities, injuries or even loss of time. However, this reduced risk depends on the effectiveness of a signal transmitter in a particular application, based on its decibel and joule rating.

With a view to increasing throughput, signals can reduce the likelihood of crane failure. State-of-the-art combination signaling devices are able not only to warn the personnel of a moving load, but also to warn the operator by means of separate tones or lights of conditions that can lead to downtimes. This can include collision avoidance, overspeed alarms, hoist breakage alarms, overload alarms, and over-temperature alarms from VHD. These, in turn, save costs as companies that use cranes to facilitate production rely on them to generate income. If the crane fails, the likelihood of a significant loss of revenue is high. So if you signal that conditions need to be changed or maintenance work done, the risk of that loss of revenue is reduced.
