FAQ's
How do I read the size of U-bolts?
- U-bolts are measured by the intermediate dimensions. For example, on the U-bolt 50x43 mm M10 | Grey | 50x43 mm | Steel | 405401, you can see an illustration with the dimensions.
Are brake shoes sold as a set?
- Yes, they are always sold in pairs so both sides can be replaced. This is important for safety.
Why is it important to weigh your ball nose weight?
- Correct ball nose weight helps prevent swaying and dangerous situations on the road.
How do you measure the drawbar / ball nose weight?
- You can do this with a ball nose weight gauge or by choosing a jockey wheel with a built-in ball nose weight gauge.
How much can a winch pull?
- This is always stated in the product information. To be safe, choose a winch with slightly more capacity than you need.
How big should a trailer net be?
- Always choose a net that is 50 cm longer and 50 cm wider than your trailer, to account for overhanging load and to secure it over the trailer.
Which axle and brake parts wear out the fastest, and why?
- Common wear points are brake shoes, bearings, and brake drums due to friction and heat during braking. Regular inspection helps prevent premature failure.
How do you choose the right brake parts for different loads?
- The brake component must match the trailer’s weight and braking system. Heavier trailers need more robust brake systems.
What is the purpose of mudguards, and when are they required?
- Mudguards protect the load and following traffic from splashing water and dirt. In many countries, they must be mounted around the wheels.
Which materials are used for mudguards?
- Mudguards are available in plastic, steel, or aluminium, each with its own advantages in terms of weight, durability, and corrosion resistance.
Why is a jockey wheel important on a trailer?
- A jockey wheel supports the trailer drawbar, makes manoeuvring easier, and prevents tipping when the trailer is not connected to a vehicle.
Why is the right coupling essential for safe driving?
- A coupling ensures a stable connection between the vehicle and the trailer. An incorrect or worn coupling can cause dangerous situations.
Which safety components belong with a coupling?
- Safety chains or breakaway cables are essential so the trailer brakes or stops in the event of an unexpected disconnection.
What anti-theft solutions are available for trailers?
- Common solutions include coupling locks, wheel clamps, and secured padlocks to prevent theft of the trailer or semi-trailer.
When is hardware and locking equipment important?
- Hardware and locking equipment, such as hinges and latches, are crucial for doors, boxes, or superstructure parts on trailers to ensure safe access and protect goods.
How can I protect my trailer against theft?
- Protect your trailer with an SCM-approved coupling lock or wheel clamp. This significantly reduces the risk of theft.
Do I need a separate inspection?
- In the Netherlands, trailers do not require a periodic APK inspection. However, they must be safe and properly maintained.
What is the difference between single axle and tandem axle?
- Single axle: more manoeuvrable, lighter, and more affordable. Tandem axle: more stable and suitable for heavier loads.
What differences are there in jockey wheels?
- There are different jockey wheel sizes, suitable for specific trailers depending on weight.
Which plug do I need?
- You can choose from 7-pin, 8-pin, and 13-pin plugs. An wiring diagram can be added with the corresponding functions.
Which types and brands of lighting are available?
- You have Aspöck, Radex, AJBA, Fristom, and own-import products such as lighting sets or light bars.
What are the most important electrical components on a trailer?
- Important parts include cables, plugs, lighting, and sometimes sensors for safety and visibility.
Why is LED lighting becoming more popular on trailers?
- LED lighting has a longer lifespan, is more energy-efficient, and provides better visibility than traditional lamps.
Which products fall under load securing?
- Ratchet straps, nets, and lashing points are used to secure cargo safely and prevent shifting during transport.
What are loading ramps used for?
- Loading ramps are used to load vehicles, machines, or equipment onto a trailer via an inclined surface.
Which tools are essential for fitting or maintaining trailer parts?
- Torque wrenches, bearing pullers, and special tools for brake assembly are often used in professional maintenance.
What are the main replacement parts for caravans?
- Typical parts include stabilisers, corner steadies, lighting, and couplings, which wear out with intensive use.
What should you pay attention to with boat trailer parts?
- Corrosion resistance is important because of water exposure. Parts such as keel rollers and mudguards are often made of rust-resistant materials.
Which specific parts are important for horse trailers?
- High-load axles, strong lighting, and reliable couplings are crucial because of the higher weight and animal safety.
Which seasonal items are relevant for trailer use?
- Common seasonal products include anti-slip mats and winter and summer accessories to maintain safety and functionality in changing weather.
