Rigid vs Articulated Dump Trucks | Which do You Need?

Summary

This video script discusses the critical factors to consider when choosing between a rigid and articulated dump truck. It highlights the historical development of dump trucks and compares their features, such as steering and terrain adaptability. The script also evaluates job requirements, including terrain type, material handling, and budget considerations. It concludes with advice on selecting the appropriate truck based on long-term job needs and the importance of thorough inspection before purchase.

Takeaways

• 🚚 **Rigid vs. Articulated Dump Trucks**: There are two main types of dump trucks to consider - rigid and articulated.
• 🏗️ **Historical Background**: The dump truck was invented by Canadian Robert T. Mawini in 1920.
• 🚜 **Rigid Dump Truck Features**: Rigid dump trucks have a fixed chassis with a moving bed and traditional steering.
• 🔗 **Articulated Dump Truck (ADT) Evolution**: ADTs evolved from tractors with reinforced wagons in the 1950s to modern off-road vehicles with a hinge between the cab and dump box.
• 📈 **Technology in Dump Trucks**: Both rigid and ADTs have similar technologies like payload monitoring, collision warnings, and telematics.
• 🏋️‍♂️ **Terrain Suitability**: Rigid trucks are best for graded surfaces, while ADTs excel in rough terrain with their all-wheel drive and low center of gravity.
• 🔄 **Maneuverability**: ADTs offer better maneuverability in tight spaces and uneven terrain due to their wider tires and suspension system.
• 📦 **Load Capacity**: Rigid dump trucks can carry larger loads and are better for longer distances and higher speeds.
• 💼 **Job Duration**: Rigid trucks are ideal for long-term jobs with well-maintained roads, whereas ADTs are more flexible for varying conditions.
• 💵 **Budget Considerations**: The choice between new or used dump trucks should be based on hard requirements, with ADTs potentially having higher maintenance costs.
• 🔧 **Maintenance**: ADTs have more components to maintain, which can affect the overall cost of ownership compared to rigid dump trucks.

Q & A

Who invented the dump truck?

The dump truck was invented by Robert T. Mawini, a Canadian inventor who created and patented it in 1920.

What is the main difference between a rigid and an articulated dump truck?

A rigid dump truck has a fixed chassis with the cab and dump body sitting on top, using traditional rack and pinion steering. An articulated dump truck (ADT) has a hinge between the cab and dump box, allowing the truck to pivot, and it is an off-road all-wheel drive vehicle.

What are the key technological features common to both rigid and articulated dump trucks?

Both rigid and articulated dump trucks have similar technology such as payload monitoring, collision warning systems, and telematics. They also both have traction and downhill speed control.

What factors should be considered when choosing between a rigid and an articulated dump truck?

Factors to consider include the type of job site, the type and weight of materials to be handled, the length of time the dump truck will remain on the site, and your budget.

Why are rigid dump trucks better suited for certain job sites?

Rigid dump trucks are best for job sites with a graded surface and well-established, well-maintained roads that are not too steep, generally up to 15 to 20 percent grades.

What terrains can an ADT handle that a rigid dump truck cannot?

An ADT can handle nearly any terrain, including muddy, slippery, and softer ground. It can manage steeper grades up to 35 percent and haul distances up to ten thousand feet.

What are the advantages of ADTs in terms of maneuverability?

ADTs have better maneuverability in challenging situations such as tight switchbacks or low ceiling heights due to their wider tires and lighter weight compared to rigid trucks.

How does the load distribution on an ADT affect its ability to travel over uneven terrain?

The load is more evenly spread out on an ADT due to its wider tires and suspension system, allowing it to travel over uneven terrain more readily.

What is the typical load capacity difference between rigid and articulated dump trucks?

Rigid dump trucks can handle a much larger amount of material and are able to go longer distances with heavier loads compared to ADTs.

What is the impact of job length on the choice between a rigid and an ADT?

Rigid dump trucks are best suited for long-term jobs with well-maintained haul roads, while ADTs offer more flexibility for shorter-term jobs or those requiring maneuverability in rough terrain.

How should budget considerations influence the decision between purchasing a new or used dump truck?

Budget should be considered after determining hard, soft, and dream requirements. While used dump trucks might be cheaper upfront, they may cost more in repairs later. It's important to inspect and research any dump truck, especially ADTs, due to their more complex components.
