Launching trailers are essential devices for transporting boats, both for launching and for storage. These trailers are made up of numerous mechanical and electrical components that, over time, may require replacement parts to maintain optimal functioning. Spare parts for launching trailers can vary depending on the model and specifications, but generally cover the following categories:

1. Wheels and tires

Wheels are one of the most wear-prone parts of hauling trolleys, especially when used on uneven or wet terrain. There are several wheel options:

• Pneumatic wheels : They offer excellent cushioning, but can lose air over time and require repair or replacement.
• Solid plastic or rubber wheels : Puncture-resistant, but less shock-absorbing than pneumatic wheels.
• Wheel Bearings : If your wheel bearings are damaged or rusty, you may need to replace them to ensure smooth, trouble-free operation.

2. Brakes and braking systems

If the launching trailer is equipped with a braking system, it's important to keep it in good working order. Brakes are typically used to prevent the trailer from moving while positioning the boat and to increase safety when the trailer is in motion.

• Mechanical or hydraulic brakes : If your braking system isn't working properly, you may need replacement parts such as pads, rotors, or hydraulic components.
• Brake cables and actuators : These components can wear out or rust and require periodic replacement.

3. Drawbar and tow hook

The drawbar and towbar are crucial for attaching the trailer to the car or support vehicle. Components that need to be replaced or repaired include:

• Towbars : If damaged or worn, they could compromise safety during transport.
• Locking Systems : Some carts have locking mechanisms that fail over time and need to be replaced.

4. Boat supports

Boat supports are the contact points between the trailer and the boat. They can be:

• Rubber or plastic rollers and supports : Rollers are used to support the boat while it is being raised or lowered into the water. If worn or damaged, they may need to be replaced.
• Tie-down straps : Nylon or other strong straps used to secure the boat to the trailer. They can loosen, become damaged, or become brittle over time.
• Side Rollers : These are useful for keeping the boat in place during transport.

5. Axles and suspension

Suspension and axles are crucial parts of the launching trailer, as they support the entire weight of the boat and absorb shock. If damaged or rusted, they could compromise the safety and stability of the trailer.

• Suspension : This can wear out over time, especially if the cart is frequently used on rough terrain.
• Axles and bearings : If the axle is not well lubricated or is damaged, the handling of the trolley will be compromised.

6. Electrical systems (for electric hauling trolleys)

Electric hauling trolleys are equipped with motors and electrical components, which require periodic maintenance:

• Electric Motor : If the motor is not working properly, it may need to be replaced.
• Battery : Batteries discharge and may need to be replaced periodically.
• Electrical Cables and Connectors : Cables can become damaged or corroded, especially if the cart is exposed to moisture. Replacing defective cables or connectors is important to the proper functioning of the system.

7. Hydraulic pipes and fittings

If the trailer is equipped with a hydraulic lifting or braking system, the hydraulic hoses and fittings should be checked. These components may wear or become damaged over time and require replacement.

8. Lighting and electrical system (for road haulage trolleys)

If the trailer is used on the road, it must be equipped with a functioning lighting system , consisting of:

• Rear lights : Lights to indicate the presence of the trolley during transport.
• Headlights and turn signals : If damaged, they must be replaced.
• Power Wires : The wires that power the lights should be checked regularly to avoid short circuits or malfunctions.

9. Hand brake and locking system

Some trailers are equipped with a safety lock or handbrake, which helps stop the trailer once the boat is positioned on the ramp. If these systems are not working properly, they should be replaced.

10. Structure and frame

If the frame or structure of the trolley is damaged, such as from rust or impact, it may need to be replaced. The welds and materials used in the trolley frame must be resistant to corrosion and weathering.
