One of the most common causes of injury and death for site workers is being struck by vehicles or machinery. In fact, site workers are two times more likely to be injured at work compared to those in other occupations. Research carried out in Europe has also found that the construction, transportation, manufacturing, and agricultural trades recorded more workplace deaths in 2017 than all other industries combined.
Large vehicles and machinery such as excavators and dumpers can be difficult to operate safely. Restricted views and multiple complex blind spots mean drivers cannot always see hazards or spot pedestrians—especially in elevated driver positions. Meanwhile, difficult working conditions, hazardous terrain, and inclement weather can exacerbate the issue.
Research has shown that 40 percent of fatal accidents on quarry sites are caused by moving vehicles and 70 percent of collisions occur at low speed because of poor visibility. Technology, such as back-up camera systems, is playing a crucial role in improving safety and, while it isn’t a new concept, the need for tailored and cost-effective solutions to meet complex requirements in the industry has become more widespread.
Using Radars for Blind Spot Detection
Safety on site is paramount and eliminating vehicle blind spots using radars is one of the most effective ways to prevent collisions. However, single radars don’t always provide the detection needed and multiple radars with numerous displays are difficult to manage and distracting for drivers.
Radar allows construction professionals to link up to eight sensors to cover all blind spots around a machine, providing object detection via CAN gateway to display data on control panels on the vehicle. Each connected radar sensor is allocated a unique ID and will transmit data for up to eight objects using frequency modulated continuous wave (FMCW) to minimize false alerts. Objects can be detected up to 98 feet away at a width of 33 feet within less than half a second, even in harsh conditions.
Radar is highly configurable and flexible, meaning safety is greatly enhanced and can be tailored to vehicles without the need for numerous monitors.
