A study by the Census of Fatal Occupational Injuries Research File concluded that 9 construction workers were killed in accidents involving bulldozers. The scary part is that this was reported between 1992 and 2003, when bulldozers weren’t as common as today. Bulldozer accidents have become increasingly common in modern construction and mining workplaces.
But did you know there are several ways to stop these accidents? You can always use bulldozers obstacle avoidance solution to prevent crashes and create a safer working environment. So, let’s learn more about this system in this detailed guide!
Why Do You Need a Bulldozers Obstacle Avoidance Solution?
A bulldozer has expensive blind spots, which are a massive reason for construction-site accidents. The worst part is that a bulldozer’s blind spots are comparatively larger than traditional sedans and SUVs.
Like every large vehicle, a bulldozer has four primary blind spots. Here’s a brief overview:
- Front Blind Spot: The immediate front of the bulldozer can be a dangerous blind spot, especially when the blades are raised. Remember, the driver’s cabin is at a significant height, even up to 3.6 to 4.5 meters in large bulldozers. Thus, smaller vehicles and pedestrians can become nearly invisible to the driver.
- Side Blind Spots: The right side blind spot is the most dangerous in bulldozers. It is farther from the operator, limiting their view. Plus, the exhaust stack, engine hood, and hydraulic components further obstruct the operator’s view.
The left side (Operator side) is comparatively less dangerous as the view is in sight. While having better visibility, the specific frame of your bulldozer can either increase or decrease this blind spot. - Rear Blind Spot: The immediate rear is just as dangerous as the right side blind spot. That’s because many bulldozer models don’t have a good rear-view mirror to see what’s going on directly behind.
These blind spots contribute largely to bulldozer crashes, injuring nearby workers and damaging objects. Here are some common accidents that occur due to these danger zones:
- Side crushing collisions, especially when turning, due to side blind spots.
- Forward crashes, particularly when the blade is raised.
- Collisions with power lines, poles, and higher structures due to limited elevated visibility.
- Backing/reversing accidents because of minimal to zero rear visibility.
How Can Bulldozers Obstacle Avoidance Solution Help?
A bulldozers obstacle avoidance solution helps operators by keeping them updated on their surroundings, especially their blind spots. So, an operator can prevent scenarios that lead to collisions and drive safely.
Here’s a detailed look at how obstacle avoidance solution bulldozers work:
1. Blind Spot Detection
An obstacle avoidance sensor monitors your blind spots to ensure the bulldozer doesn’t collide with other vehicles, objects, or pedestrians. Typically, it has an area coverage between 5 to 30m. This range is enough to cover all four blind spots and detect a potential threat.
Remember, blind spots are a massive threat to bulldozers and their surroundings. Hence, an obstacle avoidance system (OAS) effectively solves this problem and ensures a safer working environment.
2. Real-time Alerts
What if a potential threat has entered your bulldozer’s proximity? Don’t worry, because OAS will send you real-time alerts to keep you posted. Whether it is a stationary object, a worker, or a moving vehicle, obstacle avoidance sensors can detect everything.
They immediately trigger warnings to notify the operator. Now, this alert can vary depending on the specific OAS model. However, the most common choices include flashing LED lights, buzzer sounds, and seat vibrations.
3. Various Alert Levels
Most obstacle prevention systems use several alert levels to categorize a potential threat. Let’s say you are using an OAS with buzzer warnings. The first level of alerts will begin when an object is at the maximum distance from the bulldozer. At this level, the system might not produce very minimal warnings.
The second level initiates when the distance gets shorter. Then, you will get longer buzzer warnings with intervals. However, if the situation gets critical, you will hear even alerts without intervals. It determines the seriousness of the scenario and how quickly things can escalate if the operator doesn’t take action.
4. Additional Features
A modern bulldozers obstacle avoidance solution may offer additional features, including GPS navigation, driver monitoring system, automated braking, etc. These functions increase the overall functionality of a standard OAS. Plus, they make operating a bulldozer even safer and enhance operational efficiency.
Alternatives to Bulldozers Obstacle Avoidance Solution
Does the bulldozers obstacle avoidance solution not fit your needs? There’s no need to worry. The market has many alternatives that similarly solve a bulldozer’s blind spot problem and minimize the chances of accidents. Here are the best ones:
1. Blind Spot Mirrors
Specialized convex or concave blind spot mirrors can provide increased vision for your surroundings. They can reduce the areas of your bulldozer’s danger zones. The best part is that you can position them yourself. It helps operators find the right angle that specifically eliminates their bulldozer’s weak point.
On top of that, blind spot mirrors are cheaper than all advanced driving assistant systems. Their simplicity appeals to both new and experienced bulldozer operators alike. Although they do increase the operator’s vision, they may not fully eliminate the blind spot. Plus, frequent repositioning is inconvenient and sometimes forgetful.
2. Blind Spot Monitoring System
A blind spot monitoring system works pretty much the same as an obstacle avoidance solution. It uses sensors (microwave or ultrasonic) to detect objects in the bulldozer’s proximity. However, blind spot monitors don’t have automated features like an OAS. They also lack the multi-level warning system, which is common in most obstacle detection systems.
That said, BSM systems offer up to 4 sensors, covering all four blind spots. Their simple working mechanism and customizable alert system suit bulldozer operators of all levels.
3. Camera Monitoring System
Camera-based systems are also effective for bulldozers. You can mount up to 4 lenses to cover all blind spots. But there’s a wide variety in camera-based driving assistance systems.
Most commonly, you will find a 360° camera system for bulldozers. They provide a bird’s-eye view of the surroundings. You can view the real-time video output on a screen mounted in the driver’s cabin.
Another common device is a backup camera for bulldozers. However, it only eliminates the rear blind spot. It activates when the bulldozer is reversing and provides a real-time display of the area immediately behind.
Although camera-based systems are effective, they may divide the operator’s attention. That’s because they always have to monitor their surroundings on the screen before making critical moves, like turning.
Future Trends in Bulldozers Obstacle Avoidance Solution
The ADAS industry is rapidly growing and introducing new technologies for every vehicle. The same goes for the bulldozers obstacle avoidance solution. Here are some future predictions, considering the trends being introduced today:
Data Collection & Machine Learning
Obstacle avoidance systems use smart algorithms to detect a potential threat. However, it is expected to go beyond just that. Future OAS models will collect data from near-miss events. Based on that, they will improve their detection algorithms, which are currently static.
Seamless Integration
Today, most OAS models might not integrate with other aftermarket safety features. But this problem would not exist in the coming years. The newer models will be more likely to pair and work in sync with advanced driving assistance systems, like a backup camera. Having more safety features exponentially increases your and others’ safety.
Autonomous & Semi-Autonomous Operations
Today, you can find some obstacle avoidance systems with automated features like emergency braking. But, they are not as widely available as traditional models. The future looks packed with automated features to support the operator. It includes pathfinding, geofencing operational boundaries, and taking emergency action to prevent collisions.
Many people might find this level of automation controversial, as they would have less control over their bulldozers. On the bright side, it will take a huge burden off your shoulders and let you focus solely on your business operations.
Synchronized Worksites
What if your bulldozer obstacle avoidance can pair with a worker’s personal proximity detection system? It can minimize the chances of collisions and create a connected worksite. A common digital map will ensure all the workers and vehicles stay safe, maximizing operational efficiency.
Conclusion
Hopefully, now you know all about the bulldozers obstacle avoidance solution. Having a safe and secure worksite has many benefits.
