Towbar bend by Bike carrier

Lilaton's Photo Lilaton 07 Aug 2017

I would like to know if somebody ever experienced that the towbar broke or bended by attaching a bike carrier to the ball of the towbar.?

Nope. Also it does not quite make sense that a structure built to carry and pull a few ton will bend/brake under 50kg's load.

Makes no sense. No way you can get that much torque from attaching a bike carrier and even if you put 4 bikes on it, still ... no.

 

Maybe you can explain a bit more?

Firstly is it a SABS approved towbar? Did it bend or did it break. Some pictures would help

Maybe a theoretical question?

Could be but then again the heading is a statement and not a question.

Now that's cool. Was wondering how they get it up there. Googled the image, Wow those racks are intricate. Well some of them just have a ramp but some of the tilting ones are an engineering masterpiece. So that bike weights about 200kilos? The rack possibly 50kilos? That's a lot of downward weight so far behind the rear axle. I wonder if its advisable to improve the rear suspension? Yes a caravan weights a lot more but its forces are in a different direction. The downward weight from a caravan, if packed correctly should be very little.

There is a reason there is a tow ball maximum weight rating... its a downward weight rating then there is the towing capacity rating which is also on there.

 

Have you seen how some of these backyard towbar places fit a towbar and what they attach it to on the car??? scary stuff.

 

If you don't know enough to ensure you get quality - buy a brand name or oem towbar and pay the extra - they come with quality guarantees at least - and then don't be a n0b when you use it.

Our tow bar happily pulls 1.8 tons of horse box, but has a vertical Mass limit of 75KG, same as our last one. So presumably if it were overloaded vertically it would bend or break

Swop the alu frame for carbon - should get the weight under 50 kg's oh and you do not need 100mm I-beams for bike rack frame :eek:
