The trailer hitch is used for towing because it provides a secure and stable connection between the towing vehicle and the trailer. It allows the towing vehicle to pull the weight of the trailer without putting excessive strain on the vehicle's frame or suspension. The trailer hitch also allows for easy attachment and detachment of the trailer, making it a convenient and practical tool for towing various types of trailers, such as boats, campers, and utility trailers. **

The trailer with a towing capacity of 1500 kg is the second trailer. It is designed to handle heavier loads compared to the first trailer, which has a towing capacity of 1000 kg. The second trailer's higher towing capacity makes it suitable for transporting larger items or heavier equipment. It provides more flexibility and capability for towing heavier loads while on the road. **

When towing a trailer, it is important to consider the weight of the trailer itself, the weight of the cargo being carried in the trailer, and the tongue weight, which is the downward force exerted on the hitch by the trailer. Additionally, the towing capacity of the vehicle and the weight distribution of the cargo inside the trailer should also be taken into account to ensure safe and stable towing. Overloading the trailer or exceeding the towing capacity of the vehicle can lead to dangerous driving conditions and potential accidents. **
