How to Load a Car on a Trailer with a Winch

VD August 08 2021

Loading a car on a trailer can be a time- and effort-consuming task, especially when the car’s power isn’t working due to a technical difficulty. You are likely to feel distressed at this point when you’re standing alongside the road with your punctured tire or an overheated engine. You have got two choices. Either use a drill-powered winch to load your car into the trailer or try to push your car yourself.

In such conditions, pushing your car by yourself isn’t an option. If you own a proper sedan or a powerful hatchback, then using a winch to pull the car onto the trailer is a must-to-do task.

In the US alone, hundreds of calls are received every day for the need to get someone’s car on a trailer. This proves how much the car trailer winch business is booming. But the fun fact here is that not most people know how exactly a drill-powered winch works.

The working principle behind a drill-powered winch

It is all based on the laws of physics. The massive power generated by a cordless drill-powered winch that pulls the car onto a trailer is generated through torque. A winch is a motor with a cord attached to it. The cord length may vary based on the winch manufacturing company. Talking about the overall durability and effectiveness of the cord, the cord used in most winches is very strong.

As the motor rotates by using power provided in voltage through an external force, it generates a certain amount of torque. According to physics, the greater the arm length means greater the torque will be produced. This allows generating a more significant amount of force for the winch to pull the car onto the trailer.

In the above-given case, the arm length is the distance between the winch and the car, which is quite enough already. The winch is placed in the innermost end of the trailer. At the same time, the opposite end of the cord is attached to the car standing on the road. Based on various car models and weights, the type of drill-powered winch to be used also varies.

Is a drill-powered winch effective?

As compared to the idea of pushing your car up a trailer, yes. But this doesn’t mean that a cordless drill-powered winch is a good option in every situation. Sometimes, the car is too heavy compared to the pulling capacity of the winch. There’s no way the winch can successfully pull a heavy vehicle onto the trailer.

There are cases reported of some minor injuries due to some built-in errors with the drill-powered winch design. These errors are mostly related to the rotating motor, resulting in a sudden loss of all the pulling force that’s pulling the car up. This can cause injuries to a person standing nearby.

That’s why almost every car trailer winch comes with a pre-mentioned pulling capacity based on the car's weight. For instance, in the market today, we have got 500 pounds or 750 pounds pulling capacity winches. Based on the average of cars driven by the general public, these car trailer winches are a great choice to do the job.
