A tarp system is a mechanical assembly designed to cover and uncover the open bed of a truck, trailer, or container. These systems are essential for transporting loose materials like gravel, sand, grain, or waste, as they keep the load contained and protected from the elements. By using a dedicated system rather than a loose sheet of plastic or fabric, operators can secure their cargo quickly and safely.
Whether you are a fleet owner, an independent driver, or someone renting a dump trailer for a home project, understanding how tarp systems work is vital. These systems vary significantly in design, operation, and material. Choosing the right one depends on the type of vehicle you have and the specific cargo you intend to carry.
The Importance of Tarp Systems
Tarp systems serve several critical functions beyond simply covering a load. In many regions, hauling an uncovered load is illegal and can result in heavy fines. These laws are in place to prevent debris from flying out of trucks and causing accidents or damaging other vehicles on the road.
Beyond legal compliance, tarp systems protect the cargo from weather conditions like rain, snow, and wind. For agricultural haulers, this prevents grain from getting wet and spoiling. For construction haulers, it ensures that materials stay dry and manageable for the job site. Additionally, a well-fitted tarp system improves the aerodynamics of a vehicle, which can lead to better fuel efficiency over long distances.
Common Types of Tarp Systems
There is no one-size-fits-all solution when it comes to tarping. Different hauling industries require different mechanical designs to ensure the load is covered effectively. Below are the most common types found on the road today.
Flip Tarp Systems
Also known as front-to-back systems, flip tarps are most commonly seen on dump trucks and dump trailers. They consist of two metal arms attached to the sides of the truck bed. A spring mechanism or motor rotates these arms to pull the tarp from the front of the bed to the back.
These systems are popular because they are fast and relatively simple to maintain. They are ideal for loads that do not exceed the height of the truck bed walls. However, they may not provide a completely water-tight seal at the sides.
Side-to-Side Roll Systems
Side-to-side systems are the standard for agricultural trailers and grain carts. The tarp is attached to one side of the trailer and is rolled across the width of the bed using a long pole or an electric motor. Once it reaches the other side, it is latched down securely.
These systems are excellent for protecting cargo from moisture because they provide a tight seal across the entire top of the trailer. They are also useful for wider loads that might interfere with the vertical movement of a flip tarp system.
Cable Tarp Systems
Cable systems use a series of bows (metal supports) that slide along cables or tracks running the length of the truck bed. When the system is engaged, the bows pull the tarp forward or backward, much like an accordion. These are frequently used on large waste containers and scrap trailers.
The primary advantage of a cable system is that it can accommodate loads that are heaped higher than the sides of the trailer. The flexible nature of the cable and bow design allows the tarp to drape over uneven cargo without getting stuck.
Flatbed Tarp Systems
Flatbed trailers require a different approach because they lack side walls. Sliding tarp systems, often called Conestoga systems, use a frame and track assembly that covers the entire flatbed. The framework can slide forward or backward to allow for loading from the side or top.
These systems are expensive but highly efficient for flatbed operators who frequently haul weather-sensitive machinery or steel. They eliminate the need for the driver to manually throw heavy tarps over the load, which significantly reduces the risk of injury.
Manual vs. Automatic Tarp Systems
One of the biggest decisions when selecting a tarp system is whether to go with a manual or an automatic (electric) version. Each has its own set of advantages depending on your budget and how often the system will be used.
- Manual Systems: These require the operator to use a hand crank or a pull-rope to move the tarp. They are more affordable to install and have fewer mechanical parts that can fail. However, they require more physical effort and time.
- Automatic Systems: These use electric or hydraulic motors to move the tarp at the push of a button. They are much faster and allow the driver to stay safely inside the cab during operation. While they have a higher upfront cost, they improve productivity and safety.
Choosing the Right Tarp Material
The material of the tarp itself is just as important as the mechanical system. The two most common materials are mesh and vinyl, and each serves a specific purpose.
Mesh Tarps are made from a breathable fabric that allows air to pass through while containing larger debris. These are perfect for hauling gravel, rocks, or wood chips where water protection is not a priority. Because they allow air to flow, they are less likely to flap violently in the wind.
Vinyl Tarps are heavy-duty and waterproof. They are used for hauling materials that must stay dry, such as asphalt, grain, or palletized goods. Vinyl is more durable than mesh but is also heavier and more susceptible to catching the wind if not secured tightly.
Maintenance Tips for Tarp Systems
To ensure your tarp system lasts for years, regular maintenance is required. A failing tarp system can lead to downtime and expensive repairs. Follow these steps to keep your system in top condition:
- Inspect for Tears: Regularly check the tarp fabric for small holes or frayed edges. Patching a small hole early is much cheaper than replacing the entire tarp.
- Check Tension: A loose tarp will flap in the wind, which causes rapid wear and tear on both the fabric and the mechanical arms. Ensure the tensioning springs or straps are adjusted correctly.
- Lubricate Moving Parts: If you have a mechanical system, grease the pivot points, bearings, and tracks regularly to prevent rust and ensure smooth operation.
- Clean the Tracks: For cable or sliding systems, debris can build up in the tracks. Clean them out frequently to prevent the motor from straining.
- Check Electrical Connections: For automatic systems, inspect the wiring for corrosion or loose connections, especially near the battery and the motor.
Conclusion
Tarp systems are an indispensable tool for anyone involved in hauling and transportation. By selecting the right combination of mechanical design and material, you can ensure that your cargo remains secure, your vehicle stays compliant with the law, and your operations run smoothly. Whether you choose a simple manual flip tarp or a sophisticated automatic sliding system, regular maintenance will be the key to your system’s longevity.
