The owners of inflatable swimming equipment are well aware that transportation PVC Hand-held long distances are extremely tedious and sometimes impossible to do without assistance, especially for models longer than 3.5 meters or those equipped with heavy loads. fiberglass-bottomThat is why the decision to buy a nose cart becomes not just a whim, but an urgent necessity for every boater who values his comfort and time.
The modern market offers many options for keel and nose devices that allow one person to easily move a equipped boat from car to water and back. However, in order not to make the mistake of choosing and not to purchase a device that will have to be reworked with a file, you need to understand the design features and materials. gurney It is able to extend the service life of the transom and the cylinder itself, reducing mechanical loads during loading.
In this article, we will discuss in detail what to look for before buying, compare different types of designs and give practical recommendations for installation, you will learn why it is sometimes more profitable to build a device yourself, and in which cases it is wiser to buy a ready-made factory kit from a proven manufacturer.
Design features of nose trolleys for PVC
The main difference between the inflatable boat trolley and the rigid hull is the way it attaches and distributes the load. carry-cart It should be supported on the keel or rigid bottom without deforming the cylinders. Most often, the structure is a frame made of stainless steel or aluminum, which is attached to the transom or inserted into special sockets.
The key element here is foot-field It is important that these elements have a soft coating or a round shape that excludes puncture of PVC fabric, metal parts that contact the sides must be either removed or securely insulated with special linings.
⚠️ Warning: Never use aluminium boat trolleys without major refinement. The sharp corners of a metal frame can instantly damage PVC tubes under the weight of the boat, which will lead to expensive repairs on the shore.
There are two main types of fastening: stationary (on bolts to the transmolor) and removable (inserted into grooves or fastened with belts). The first option is more reliable for heavy boats, the second is versatile and does not require transmolor drilling, which is important to maintain warranty on some models. flyboat.
What do cart frames make of?
The most commonly used stainless steel is AISI 304 or anodized aluminum. Steel is heavier but stronger and cheaper. Aluminum is lighter, doesn't rust at all, but costs more and can deform when overloaded. For PVC boats with engines up to 15 hp, aluminum is quite enough.
Selection criteria: wheels, materials and load capacity
When choosing a cart, first look at wheels, which determine whether you can drive on sand, rocks or dirt, and large diameter inflatable wheels (300-400 mm) are ideal for soft ground, but are prone to punctures. Cast wheels polyurethane or rubber with a solid aggregate will never go down, but they can burrow on the sand.
The second critical factor is the load capacity, which is to add up the weight of the boat, the engine, the fuel, the battery and the equipment, the safety margin should be at least 30%. If the boat weighs 80 kg and the engine weighs 40 kg, the trolley should withstand at least 150-160 kg, because when driving on unevenness, the dynamic load increases.
Pay attention to the quality of welds and joints. Budget models often use bolt joints that can unwind from vibration during transportation. stainless fastener preferably galvanized, which eventually will begin to rust in salt water.
It's also worth evaluating the width of the track. A too narrow trolley will be unstable on the roll, and a too wide one may not pass into the gate or between trees on the wild shore. The optimal width of the base for PVC boats is 350-450 mm.
Comparative table of popular models of carts
To simplify the buying decision process, we have compiled a comparative analysis of popular design types on the market, which will help determine which model is best suited to your specific operating conditions.
| Parameter | Budget (Steel) | Medium (Aluminum) | Premium (Stainless steel) |
|---|---|---|---|
| Frame material | Galvanized steel | Aluminum profile | Nerzh. steel AISI 304 |
| Structure weight | 8-10 kg | 5-6 kg | 7-8 kg |
| Load capacity | 150 kg | 200 kg | 300 kg |
| Type of wheel | Inflatable 260 mm | Cast 300 mm | Turning casts |
| Price. | Low. | Medium | High. |
As you can see from the table, the overpayment for stainless-steel It's a good idea if you plan to operate a boat in salt water or keep a cart in your garage all year round. Aluminum options are the middle ground for most anglers.
Choose a cart with a margin of safety of at least 30% of the real weight of the equipped boat to avoid axle failure at the most inopportune time.
Instructions for installation and installation on the transom
Installing a nose trolley is a process that requires carefulness, especially when it comes to drilling a transom. Before starting work, make sure you have all the tools you need: a drill, a metal drill (or wood, depending on the transom material), a set of keys and sealants.
The installation process usually looks like this:
- 🔧 Mark the mounting places on the transom using the trolley as a template, and make sure the holes don't fall on the reinforcements or seams.
- 🔧 Drill holes with a diameter corresponding to the fastening bolts, and treat the edges of the hole with an anti-corrosion composition.
- 🔧 Put the layer on. sea-sealer around the holes and on bolts before installation to prevent moisture from entering the transom.
- 🔧 Secure the cart with bolts, using wide washers to distribute the load, and tighten the nuts with moderate effort.
If your model of the trolley is removable and does not require drilling, the process is simplified to lock the belts or insert pins into the sockets, however, even in this case it is recommended (regularly check) the tension of the belts and the condition of the fixing elements.
☑️ Preparation for installation
Once installed, make sure to do a test load, put the boat on the trolley, raise your nose and swing the structure from side to side, there should be no backlashes, creaks or transom deformation.
Maintenance and care of the wheel system
Even the best quality. boat-cart After every departure, especially at sea, you need to wash all the elements with fresh water, salt and sand are the main enemies of bearings and metal compounds.
Once a season, lubricate the moving parts. For wheel bearings, use lithium lubricants that are resistant to water washing. Rubber wheel elements (if any) are useful to treat with special compounds that prevent drying and cracking from ultraviolet light.
⚠️ Warning: Do not store the cart with pumped wheels in direct sunlight or at heat sources. Overheating of the air inside the chamber can lead to explosion or irreversible deformation of the rubber.
If you notice that the wheels have started to wag or a backlash on the axle, you need to immediately tighten the nuts or replace the bearings. Operating a faulty trolley can lead to the boat tipping over when launching.
Lubricate threaded joints with an anti-corrosion spray (such as WD-40 or analogues) before winter storage - this will save you hours of unscrewing the boiling nuts in the spring.
Homemade carts: is sheepskin worth making?
Many gold-handed craftsmen are thinking about making a cart DIY, and indeed, with access to welding and metal, you can save up to 50 percent of the cost, but you have to consider the cost of materials: quality stainless steel and good wheels are not cheap.
Home-made structures often sin overweight and lack of ergonomics. Factory models are tested to balance the boat to avoid pecking at the nose when moving. At home, it is difficult to achieve the perfect center of gravity without special equipment.
However, if you are making a trolley for a non-standard boat (for example, with a very wide nose or a specific keel), an individual project may be the only right solution.
Where do I get the blueprints?
Simple drawings can be found on powerboating forums or in specialized magazines, but it is better to adapt the finished solution to your size than to copy blindly.
Where to buy and what to pay attention to when ordering
You can buy a PVC boat bogie in specialized water shops and large marketplaces. When ordering online, carefully study photos and reviews, paying attention to the quality of welding and equipment. Often the declared diameter of the wheels in the picture and in reality is different.
When buying live, be sure to ask the seller to assemble the cart and rock it. Check the wheels, the absence of sharp edges on the metal and the completeness of the fastener. A good seller will always offer additional accessories such as belts or cases.
Don't forget. warrantyOn factory products, it is usually between 6 and 12 months, which is an indicator of the manufacturer's confidence in their product. Cheap Chinese counterparts without a warranty can fail after the first season of active fishing.
Can I use a cart for different boats?
Yes, if the difference in size and weight is not critical, versatile trolleys with adjustable belts or sliding frames allow you to adapt the device for boats with lengths from 3.2 to 4.5 meters. However, for boats with different types of bottom (NDNDM and floorboard) may require reconfiguration of the supports.
How to transport a cart in the trunk of a car?
Most modern models are collapsible or foldable. The frame can be divided into 2-3 parts, connected by bolts or pin locks. When assembled, the trolley takes up a minimum of space, often fitting into a boat bag.
Do I need to remove the motor when transporting on a trolley?
For short-term movement on a flat shore (100-200 meters), the engine can be left, but for long-term transportation over rough terrain or if there is a risk of severe shaking, it is better to remove the engine so as not to damage the lower unit and the transom of the boat from vibration.
What is the best wheel diameter for a sandy beach?
The diameter and width of the wheel are critical for sand, with a minimum diameter of 350 mm, preferably 400 mm or more, narrow wheels will fail, so choose models with a wide profile or the possibility of paired wheels.
