Why Do Garbage Trucks Have Two Steering Wheels?

Garbage trucks often have two steering wheels for a variety of reasons, primarily related to maneuverability and safety. This design choice ensures that these vehicles can efficiently collect waste in tight spaces, ensuring both efficiency and safety during operations.

Maneuverability

One of the main reasons garbage trucks are equipped with dual steering wheels is to enhance their maneuverability, especially in residential areas and narrow streets. These vehicles are often required to operate in confined spaces where precise control is essential for safe and effective waste collection. By having a second steering wheel, drivers can better control the vehicle's movements, making it easier to navigate through tight corners and around obstacles.

Driver and Passenger Steering

In some configurations, the second steering wheel is positioned on the passenger side. This arrangement allows the driver to have a better view of the curb and the collection area, which is particularly useful when the truck is positioned close to the side of the road for waste collection. The passenger wheel helps the driver navigate the vehicle more precisely, reducing the risk of collisions with surrounding objects.

Safety

The dual steering system also enhances safety for the driver by providing additional control over the vehicle during complex maneuvers. This added control reduces the risk of accidents, even in challenging conditions. Furthermore, the system is designed to improve situational awareness, helping drivers maintain a safe distance from pedestrians, vehicles, and other obstacles on the roads.

The Apprentice's Utility

Another reason for the additional steering wheel is to include the apprentice driver. Experienced garbage truck operators often convince their apprentices that the second steering wheel has an important function or that they are contributing to the operation by using it. This inclusion makes the apprentice feel more engaged and vital to the team, which is crucial in the sanitation industry where maintaining a positive and cooperative team dynamic is essential. An apprentice who feels like they are helping is much less likely to cause disruptions or disturbances, which can be detrimental in this high-pressure environment.

Global Adaptations

Interestingly, the design of the second steering wheel is not unique to specific types of garbage trucks. For instance, side loader garbage trucks, which are common in Australia, also feature a second wheel for the same reason. These trucks are typically right-hand drive (RHD) but designed to operate on the left side of the road. The setup includes a joystick used to operate the arm that lifts and empties the bins, further highlighting the importance of dual steering for safe and efficient operation.

Conclusion

The inclusion of two steering wheels in garbage trucks is a smart design choice that improves maneuverability, enhances safety, and promotes a positive and cooperative work environment. Whether it's for operational efficiency, safety, or to keep the apprentices engaged, the dual steering system is an essential feature that has stood the test of time in the sanitation industry.
