Transporting inflatable boats is often a test for the back and nervous system of the owner, especially if we are talking about heavy models with rigid floorboard or outboard motors, which can weigh more than 50-70 kilograms. Truck-truck trailer for PVC boat It is becoming the technological solution that radically changes the approach to launching.
Unlike traditional trolleys, where a boat has to be dragged or rolled overboard by hand, rollover designs allow the vessel to be launched with little or no effort, especially for solo fishermen or hunters who are often left alone with heavy machinery on slippery shores.
In this article, we will discuss the design of such trailers, consider their advantages over stationary analogues and help you determine the best model for your type of boat. You will learn why the rollover mechanism is not just a whim, but a matter of safety and health.
Design features of dump trailers
The structure is based on a frame made of profiled pipe, which provides the necessary rigidity and stability during transportation. It is the frame that takes the main load from the weight of the boat, the engine and additional equipment. The key element here is the hinge assembly, which connects the platform to the breather and allows you to tilt the entire structure.
Depending on the type of mechanism, rollover may occur by inertia when moving backwards or by a hydraulic/mechanical actuator. Hydraulic jack It provides smooth running, which is critical to maintaining the integrity of inflatable tubes and preventing them from damaging the edge of the platform. Mechanical systems powered by cable winches are easier to maintain, but require more physical strength.
The bed surface is usually covered with a special carpet or rubber pads that prevent slipping and protect the bottom of the boat from abrasion. It is important that when overturning, the angle of inclination is sufficient to free slip the vessel, but not excessive to avoid hitting the bow on the ground.
- 🚤 The hinge connection of the frame with the breather to ensure mobility.
- 🔩 Reinforced springs or torsion suspension to extinguish vibrations.
- 🛡️ A protective coating of a bed of wear-resistant carpet.
- ⚓ A winch with a cable for fixing and pulling up the boat.
It is worth noting that modern models are often equipped with adjustable drawer, which allows you to adapt the trailer for boats of different lengths. This universal solution allows the owner not to think about changing the trailer when upgrading the boat.
Advantages of using a rollover mechanism
The main argument for buying a dump truck is to minimize physical labor: Descent of a heavy PVC motorized boat by hand often requires the help of a second person or the presence of a perfectly flat concrete slip, which is not available in every wild parking lot. Rollover mechanism It solves the problem of lack of infrastructure on the shore.
And it also reduces the risk of damage to the boat, and when you try to pull a boat off a classic trailer, you're more likely to hit rocks, snags, or metal parts with cylinders, and when you roll over smoothly, the boat just slips into the water, and stays on the weight until it touches the water.
⚠️ Attention: Even if there is a dumping mechanism, be sure to check the reliability of the winch attachment before descent. A sharp collapse of the boat can lead to damage to the transom or leg injury.
Another important advantage is the speed of assembly and dismantling of the camp, and experienced water-engineers know that on the way back, after a long day on the water, there is little strength to carry weights, and here the ability to just go to the trailer and pull the check of the mechanism becomes a decisive factor in comfort.
And the trailer itself is safe, because dragging boats wears out faster in the guide area, and dump trucks don't have that disadvantage, because the boat doesn't rub against the frame when it's going down.
In winter, or in dry shores where the wheels can get stuck, the ability to quickly clear the platform of the load becomes a safety issue: You can pull an empty trailer out of the mud while the boat is already on the water, or vice versa, quickly load up before the car is bogged down.
Model Comparison: Mechanics vs. Hydraulics
When choosing a trailer, the buyer is faced with a dilemma: which type of rollover mechanism drive is preferred. Mechanical systems are generally cheaper and more structurally simple. They are a system of cables and blocks that are tensed by a hand winch or gate.
Hydraulic systems are more expensive, but provide incomparably higher levels of comfort. One person can easily lower a 300-400kg boat just by working with the handle of the pump. Hydraulic cylinder ensures smoothness of the process, excluding jerks that are dangerous for inflatable elements.
Maintenance requires regular lubrication of the cables and checking their integrity. Rusty or broken cable can burst at the most inopportune moment. Hydraulics require monitoring of oil levels and seals, but in general are more reliable in the long run, provided quality execution.
For owners of light boats (up to 200 kg in the assembly), the difference may not be so noticeable, and the mechanics will cope. However, for heavy complexes with a keeled bottom and powerful motors, hydraulics become almost a necessity for maintaining the health of the back.
Criteria for the selection of trailers for PVC boats
The first thing to look at is the load capacity: sum up the weight of the boat, the engine, the fuel tank, the anchor and all the other equipment you plan to carry all the time, and the safety margin should be at least 20-30% of the calculated weight. Load capacity This is a parameter that cannot be ignored.
The second important criterion is the type of bed. For PVC boats, keel beds with a V-shaped profile are ideal, which support the hull along the entire length. Flat platforms are less convenient, since the inflated bottom of the boat is rounded and can sag, which is harmful to the design of the vessel.
Wheelbase also plays a role. Single-axle trailers with wide off-road wheels are better suited to soft ground or sand, dual-axle models are more stable on the track, but have a larger turning radius and pass less on blurred shores.
How to check the quality of welding?
Carefully inspect the welded seams of the frame. They should be smooth, without burns and pores. The painting should be done by hot galvanizing or high-quality powder paint. The rust on the new trailer is a sign of a violation of production technology.
Be sure to check for lighting equipment. Even if you plan to only drive during the day, traffic rules and HIMS are mandatory, and having stop lights, turn signals and reflectors is not only the law, but also your safety on the road.
When choosing, pay attention to the manufacturer's brand. Famous brands value their reputation and use proven components. Cheap analogues can be assembled from residual materials, which will affect the product's resource life.
Technical specifications of popular types of trailers
To make the selection process easier, we have compiled a comparison table of the main specifications that are found in the market, which will help you form a primary idea of what you need.
| Characterization | Light class (up to 3.5 m) | Middle class (3.5 - 4.5 m) | Heavy class (4.5 m +) |
|---|---|---|---|
| Load capacity | 350 kg | 350 - 600 kg | 600 - 900 kg |
| Type of suspension | Resorbed | Resorbed/Torsion | Torsion |
| Descent mechanism | Mechanical | Mechanical/hydraulics | hydraulic |
| Lodge material | Aluminum/Steel | Coated steel | Stainless steel |
As you can see from the table, as the boat size increases, the requirements for the trailer increase exponentially. For heavy boats, the use of aluminum frames becomes justified, since they do not rust and are lighter than steel, although more expensive.
Torsion suspension, often found in medium and heavy classes, provides better cushioning and stability at high speeds compared to classic springs. This is important if you plan long distance runs on the track.
⚠️ Attention: When buying a used trailer, be sure to check the condition of the wheel hubs. Luft or the hum of bearings can lead to a jamming of the wheel in transit and a serious accident.
When choosing between steel and aluminum, weigh the frequency of use in salt water. Aluminum is ideal for the sea, steel requires thorough washing with fresh water after each departure, otherwise corrosion will quickly eat the frame.
Rules of operation and maintenance
The durability of your trailer depends on how you care for it. After each use, especially in salt water or muddy conditions, the structure must be thoroughly washed. Water with sand and salt, drying in hinge joints, works like an abrasive.
Regular lubrication of moving parts is the law. Rollover hinges, wheel hubs and winch mechanism require attention at least twice a season. Use specialized lubricants that are resistant to water flushing.
☑️ Seasonal trailer TE
It is better to store the trailer under a canopy or in a garage. Ultraviolet destroys rubber elements and burns out paint. If this is not possible, use a protective cover that will prevent moisture and dirt from entering.
Before each trip, check the mount of the car to the farcope. An insufficiently tight lock can cause the trailer to lose on the move.
Use silicone spray to treat rubber seals and carpet on the bed, which will prolong their life and preserve the elasticity of the materials.
Do not overload the trailer. Exceeding the permissible weight leads to deformation of the frame, overheating of bearings and, as a result, loss of controllability of the car.
Legal aspects and registration in GIMS
Many owners are wondering: do I need to register a dump truck trailer? According to the legislation of the Russian Federation, trailers for the carriage of small vessels are subject to registration in GIMS if their weight exceeds 750 kg. However, if the mass of the trailer is smaller, but it is designed to carry a boat, the rules can be interpreted differently depending on the region and type of vehicle.
For trailers weighing up to 750 kg (category "B" in the rights), registration with GIMS is not required, it is enough to have documents confirming the purchase (contract of sale, check), but it is important that the lighting equipment works properly and the trailer number (if any) is readable.
If the trailer is heavier than 750 kg, it is subject to mandatory registration, assignment of side numbers and receipt of a boat's ticket. Operation of an unregistered craft and trailer (if required) entails fines and parking of the vehicle.
Registration of a trailer in the GIMS is mandatory only if its total weight exceeds 750 kg, but the availability of purchase documents is always required to confirm ownership.
When buying, pay attention to the presence of a PTS (vehicle passport) or a certificate of account. Without these documents, it will not be possible to legally operate the trailer, and it will be extremely difficult or impossible to register it.
Frequently Asked Questions (FAQ)
Can I convert a conventional trailer into a dump truck?
It's theoretically possible, but it requires a lot of welding, a lot of center of gravity, a lot of powerful machinery, it's easier and safer to buy a finished factory product that's been tested, and a homemade product can be too heavy to withstand the load and cause injury.
What is the maximum weight of the boat can withstand the dumping mechanism?
Depending on the model. Budget mechanical options are designed for 300-400 kg. Hydraulic systems on reinforced frames can lower boats weighing up to 1000 kg or more. Always look at the specification of a particular model.
Do I need to remove the engine before rolling over?
No, you don't have to take the engine off. The boat slides into the water with the engine, and the key is to securely close the fuel system and make sure that the lower unit doesn't catch on to the elements as it descends.
How often should I change the cable on the winch?
The cable is a consumable, and you need to check it every season, and if you notice more than 10 percent of the wires breaking in one section or if you notice severe corrosion, change the cable immediately, and on average, when you're in active use, you need to replace it every 2 to 3 years.
Can I use a dump truck for the transportation of goods (boxes, building materials)?
Yes, if the design of the bed allows (for example, there are removable lozenges or a flat platform). However, remember the load capacity and dimensions. Overturning bulk cargo can be difficult without additional boards.
