How make car transporter trailer?
Transportation of large and bulky goods requires a lot of free space. The luggage compartment of the car is usually not suitable for these purposes. In this case, the best solution is to use a trailer. It is not necessary to buy it, it is possible to collect it with your own hands, following our recommendations. Are you curious about how build car transporter trailer or how build car dolly trailer? In this article we will tell you how to make car tow dolly.
Questions to which we will provide answers
How to make a hanging frame with your own hands? The frame is the trailer basis, it is its strength, rigidity, which determines the durability of the trailer as a whole. For greater reliability, it is recommended to use a welded connection of elements. First you need to determine the frame size – length and width. The size is determined by the outer edges of the frame elements. To determine the full width of the future frame, you need to add two wall thicknesses to the distance between the inner surfaces of the side walls. If the frame is directly between the wheels, and not above, to take into account the gaps between the tire and the board. After determining the size – the frame is tried on. The frame elements are united by brackets, at this stage its shape is controlled.
Connecting the trailer to the car. If self-made trailers are used, it is better to choose a coupling layer of the same size for connection. When designing this trailer element, it should be noted that the shorter the connecting part, the faster the trailer responds to the vehicle movement, which can lead to unexpected consequences. The optimal length is from 1.5 to 2.5 m, depending on the trailer intended use. As a material for a framework it is better to choose steel pipes of square sections complete with three details. Pipes are connected to the frame by welding, for greater strength it is recommended to strengthen it with corners. Before welding, the assembly is carried out in such a way that the nozzle is exactly along the trailer axis.
Connector. Assembly of the trailer is possible by means of bolts or welding. Before the final attachment to the trailer frame, to check the conformity of the dimensions of the frame tubes and the groove of the chute. The width of the groove should not exceed the pipe width by more than 5 mm. High strength of the connection is guaranteed when welding the clutch, but in case of damage, a gas burner is required for disassembly. The strength of the threaded connection is slightly lower. It is recommended to use screws of the eighth class of durability as less strong screws do not maintain shear forces. To connect two screws, the others loosen the frame element and the coupling due to the holes for the screws.
Trailer axle. There is a rule according to which the axle must be placed at a distance of 35-40% of the entire length of the trailer at the rear. When measuring the distance, you must determine the location of the future axis. You can then proceed with the final installation. The elements are connected by spot welding along the entire length of the contact. To use spring cushioning, as it provides greater softness, although it has low strength.
