Climbing Ability Evaluation of Sightseeing Buses: What Does 30% Gradeability Mean?

When choosing a sightseeing bus, the gradeability is an important performance indicator, especially when dealing with tourist environments such as mountains or steep roads. However,  in fact, most people have huge deviations in judging road slope, and sometimes even exaggerate unintentionally.

For example, there is an 18% slope in a mountain resort. After asking several people present about their judgment of the slope, we found that no one was accurate in their judgment. Everyone believed that the slope should be above 30%. But on a true 30% slope, people cannot stand and walk normally. Especially when looking down from the starting point of a few tens of meters long slope, it feels like being on a cliff. Even on a stepped road, there are many people who dare not go down, which shows how great the human illusion is.

The reason for this illusion is that due to the terrain restrictions of the scenic spot, people can almost only observe the slope from the front. The long slope extending to high places will create a sense of visual oppression, making the angle appear much larger than the actual angle, thus leading to misjudgment. If the observer is looking purely sideways, the slope is essentially true.

The maximum gradeability of Hulk Vehicle's sightseeing bus can reach 30%. What does this ability mean? Let's give you a detailed introduction below.

Definition of Gradeability

Gradeability refers to the maximum grade a vehicle can overcome without sacrificing speed and stability. The unit that represents the vehicle's gradeability is "%" of the longitudinal slope of the road, and "degree" is less commonly used. Its meaning is the ratio of the height difference between the starting and ending points of the slope to its horizontal distance (tangent value). For example, a slope of 30% means that the horizontal length of this ramp is 100 meters and the slope height is 30 meters. And a 30% slope is equivalent to 16.7 degrees. Due to this reason, many people have misunderstood and mistook the tangent value for the slope degree. The following table explains how to convert "degree" to “tangent value”.

Usually, the gradeability of ordinary vehicles is about 15%-20%. For a sightseeing bus, the 30% gradeability shows that the sightseeing bus performs very well when dealing with steep slopes and is suitable for use in mountainous areas or steep terrain.

Advantages of 30% Gradeability

Hulk Vehicle's sightseeing vehicle has a gradeability with 30%, which is at a relatively high level in the industry. The gradeability of a regular vehicle is usually between 15% and 20%, while a gradeability of 30% indicates that the bus can handle steeper slopes and more complex terrain.

The Specific Performance of Hulk Vehicle Sightseeing Bus 30% Gradeability

Wider Application Scenarios: The gradeability of 30% enables Hulk Vehicle's sightseeing bus to travel in complex terrain scenic areas such as mountains and hills, providing tourists with a wider range of travel options.

Higher Safety: When driving on steep slopes, the stability and power performance of the vehicle are crucial. The gradeability of 30% means that the Hulk Vehicle's sightseeing bus meets high standards in design and powertrain, ensuring safety when driving on steep slopes.

Improving Passenger Experience: For passengers, comfort and safety during travel are the most important. Vehicles with high gradeability can smoothly pass through various slopes, making the entire travel process smoother and more comfortable.

Advanced technical support is required to achieve a 30% gradeability, the sightseeing bus of Hulk Vehicle is equipped with a powerful system, allowing the bus to maintain strong power output and stable driving performance even under high load conditions. In addition, the chassis design and suspension system of the bus have also been optimized to cope with the challenges of steep slopes.

The 30% gradeability of Hulk Vehicle's sightseeing bus highlights its leading position in the sightseeing bus market. This performance not only expands its application scenarios, but also enhances the safety and comfort of passengers. For tourism companies and scenic area managers, this sightseeing bus is undoubtedly an ideal choice for dealing with complex terrain and enhancing the tourist experience.

In the future development of tourism, sightseeing buses with high gradeability such as Hulk Vehicles will receive more and more attention and favor, because they not only meet tourists' needs for comfort and safety, but also provide opportunities for exploring more magnificent landscapes.
