The above picture is of a Hydraulic vehicle ramp that provides a simple method of raising a vehicle from the ground, for the easy transport. Getting your car in and out of a trailer will require a ramp. This trailer has a hydraulic tilting bed, where the entire bed can lower into position to form a ramp, and then return to a level position for transport. These types of trailers are extremely useful, but they're also quite expensive.
This trailer has a "beavertail," a downwardly curved portion at the rear of the bed that effectively provides a ramp for your car (This can be used in conjunction with some of the ramp). In some cases it may be necessary to raise the front of the trailer with a hydraulic lift in order to lower the beavertail to the point where the car can be driven on to it.
Once the ramp is in place, the car can be driven on board or it can be hauled on board with a winch. The winch, which can be attached to a secure portion of the car, is usually operated by a motor. And once the car has been raised onto the trailer bed, it must be carefully positioned. Placing the car too far forward or too far to the rear can affect the trailer's stability. And, if the trailer is an open one, care must be taken that the tires are solidly on the bed and not hanging over one side.
Ramp is inclined at a certain angle from the ground. The weight of the produces downwards forces; compressing the inner face of the ramp and the outer face of ramp is under tensile stresses. As the wheel is in contact with the ramp; reaction forces are produced in order to keep the car stable on the ramp. There is strong friction force between the tires and the top face of the ramp that helps the car to be stationary (static friction). Bending moment is also observed about the bottom end of the ramp due to the weight of the car.
