Selecting the correct dump trailer size for your skid steer loader is crucial for efficient material hauling, project profitability, and operator safety. The optimal size depends largely on the skid steer’s operating capacity, the types of materials you’ll be hauling, and the legal weight restrictions in your area. A mismatched trailer can lead to equipment strain, reduced productivity, and even dangerous situations.
Understanding Skid Steer Capacity and Trailer Compatibility
The core factor influencing your dump trailer size choice is your skid steer’s operating capacity, specifically its tipping load and rated operating capacity (ROC). Tipping load refers to the weight at which the skid steer will begin to tip forward, while ROC is generally considered half of the tipping load and represents a safer working load.
Matching Trailer Capacity to Skid Steer Specifications
Never exceed your skid steer’s rated operating capacity when loading a dump trailer. Overloading not only puts undue stress on the machine’s hydraulics and engine but also significantly reduces its stability and maneuverability. Consider the weight of the trailer itself (the tare weight) when calculating the maximum allowable load.
For example, a skid steer with a ROC of 2,000 lbs. should ideally be paired with a dump trailer that, when fully loaded, does not exceed this weight limit (including the trailer’s tare weight). If the trailer weighs 1,000 lbs empty, the maximum material payload should be 1,000 lbs.
Considering Material Density
Different materials have different densities. A cubic yard of dry soil weighs significantly less than a cubic yard of wet concrete. Therefore, calculating the volume of material you plan to haul is essential. Consult a density chart to determine the weight per cubic yard of the materials you’ll be handling most frequently. This will allow you to accurately estimate the weight of your load and ensure it remains within the skid steer’s capacity and the trailer’s rated capacity.
Dump Trailer Size Options and Their Applications
Dump trailers come in a variety of sizes, typically measured in cubic yards and by axle configuration (single axle, tandem axle, etc.). Common sizes range from 6 cubic yards to 14 cubic yards and beyond.
Small Dump Trailers (6-8 Cubic Yards)
These trailers are often a good fit for smaller skid steers and lighter-duty tasks. They are easier to maneuver in tight spaces and are typically less expensive than larger models. Ideal for:
- Homeowners and small landscaping businesses
- Hauling mulch, topsoil, and gravel for small projects
- Limited space maneuverability
Medium Dump Trailers (8-12 Cubic Yards)
Offering a balance between capacity and maneuverability, these trailers are suitable for a wider range of applications. They can handle heavier loads and are often equipped with tandem axles for increased stability. Ideal for:
- General construction and landscaping
- Hauling demolition debris, concrete, and asphalt
- Medium-sized skid steers
Large Dump Trailers (12+ Cubic Yards)
Designed for heavy-duty applications and larger skid steers, these trailers offer maximum hauling capacity. They typically feature tandem or even triple axles for superior weight distribution and stability. Ideal for:
- Large construction and demolition projects
- Hauling large volumes of heavy materials
- Skid steers with high operating capacities
Choosing the Right Axle Configuration
The number of axles on a dump trailer significantly impacts its load capacity, stability, and cost.
Single Axle Trailers
Single axle trailers are generally lighter and less expensive, but they have a lower weight capacity and can be less stable when loaded.
Tandem Axle Trailers
Tandem axle trailers offer greater stability and a higher weight capacity compared to single axle trailers. They are the most common choice for general-purpose hauling.
Triple Axle Trailers
Triple axle trailers provide the highest weight capacity and stability, making them suitable for extremely heavy loads and demanding applications. However, they are more expensive and can be more difficult to maneuver.
Frequently Asked Questions (FAQs)
Here are some frequently asked questions to further guide your decision-making process:
FAQ 1: What are the legal weight limits for dump trailers in my state?
This is crucial! Federal and state laws regulate the maximum weight allowed on trailers. Overloading can result in fines and penalties. Consult your local Department of Transportation (DOT) for specific regulations.
FAQ 2: How do I calculate the payload capacity of a dump trailer?
Payload capacity is calculated by subtracting the tare weight (empty weight) of the trailer from its Gross Vehicle Weight Rating (GVWR). The GVWR is the maximum allowable weight of the trailer when fully loaded.
FAQ 3: Should I consider a gooseneck dump trailer instead of a bumper-pull?
Gooseneck trailers generally offer higher weight capacities and improved stability compared to bumper-pull trailers. However, they require a specialized hitch in the truck and can be more challenging to maneuver. They are suitable for very heavy loads.
FAQ 4: What type of dumping mechanism is best for a skid steer application?
Most dump trailers designed for skid steer use utilize a hydraulic lift system. Consider the lift angle and dumping speed, as these factors can impact productivity. Scissor lifts are common and offer good stability.
FAQ 5: What are the benefits of a power-up/power-down hydraulic system?
A power-up/power-down hydraulic system allows you to raise and lower the dump trailer bed with the push of a button. This is significantly more convenient and efficient than a manual crank system.
FAQ 6: What is the importance of trailer brakes?
Trailer brakes are essential for safety, especially when hauling heavy loads. Electric brakes are the most common type on dump trailers and require a brake controller in the tow vehicle. Ensure your skid steer and towing vehicle are equipped with compatible brake systems.
FAQ 7: How does material density affect my trailer selection?
As mentioned earlier, material density directly impacts the weight of the load. Denser materials like concrete and asphalt will require a smaller trailer or a trailer with a higher weight capacity compared to lighter materials like mulch or wood chips.
FAQ 8: Should I consider a roll-off dump trailer?
Roll-off dump trailers are ideal for projects that generate large volumes of waste or debris. They consist of a chassis and interchangeable containers, allowing for efficient loading and unloading. However, they are more expensive than traditional dump trailers.
FAQ 9: What is the best type of hitch for connecting a dump trailer to a skid steer?
A standard ball hitch is typically used for smaller dump trailers. However, larger and heavier trailers may require a pintle hitch or a gooseneck hitch for added strength and stability.
FAQ 10: What maintenance is required for a dump trailer?
Regular maintenance is crucial for ensuring the longevity and safety of your dump trailer. This includes lubricating moving parts, inspecting tires, checking brake functionality, and maintaining the hydraulic system.
FAQ 11: Can I rent a dump trailer instead of buying one?
Renting a dump trailer can be a cost-effective option for infrequent users or for specific projects. However, if you plan to use a dump trailer regularly, purchasing one may be more economical in the long run.
FAQ 12: How can I safely load a dump trailer with a skid steer?
Always load the trailer evenly to distribute the weight and maintain stability. Avoid overloading the front or rear of the trailer. Use caution when operating the skid steer around the trailer and ensure the area is clear of obstacles and personnel. Never exceed the trailer’s weight capacity or the skid steer’s ROC.
By carefully considering your skid steer’s capabilities, the types of materials you’ll be hauling, and the legal weight restrictions in your area, you can confidently choose the right dump trailer size to maximize efficiency and safety for your projects. Investing in the correct equipment is an investment in the success of your operations.
