Bracing of thetongue adds vertical stiffness to thetongue section and should be used on trailers where thetongue length exceeds 1.5m or where thetongue section has been built using undersize material, particularly on square section steel (SHS) or similar tongues. If the flex is in the beams themselves, then change directions and read about Increasing Capacity. These are now the guides to place the tongue beam. There is not a big trick, just take care with the measurements. If youre bolting them in, use the Secondstyle of gusset as above. For example, a shorter tongue is less likely to come loose from its attachment point than a longer tongue. Bolting is nice for taking it apart, and it is easier to assemble.

Too short a tongue, and you run the risk of clipping the front of the trailer with your tow vehicle when turning corners and whilst the trailer will follow the tow vehicle nicely, when reversing, the trailer will be oversensitive.

Construction is a big factor in strength. Articles are free, but of course, there are costs. Look for gusseting, triangulation, and other such techniques to indicate solid construction. Low 12 x 30 or 32 top deck. What are they for? It will also be more responsive and forgiving when reversing. Use washers on the plywood for better clamping (so it does not just pull the bolt head into the wood). Is the connection solid to the trailer frame? A Third type uses L Bar (commonly Angle Iron) to give stiffness with a combination of the above two options. To strengthen and stiffen the trailer frame where the tongue beam mounts to the frame, here is what one customer did.

After fixing the broken or loose things, then we examine other areas to reinforce and strengthen. You can avoid the inside corner curve if you space the angle.
