Advice sought on roof bars loading
Hi All,

I’m looking for some advice regarding the LR roof cross bars (not roof rack).

I need to transport a 5m long Thule sun canopy which weighs 52kg. I’m wondering if the LR roof crossbars are up to the task, especially as it would result in a 2.1m overhang front and rear as the bars are only 80cm apart.

Has anyone any experience of transporting anything similar on their bars?

According to Land Rover the maximum load that can be placed on the cross bars is 94 kg so you should be ok weight wise but I haven't tried it as I have the roof rack Confused

Edited to add all the warnings from Land Rover

The load must be evenly distributed over the area of the cross bars as illustrated. The centre of gravity of the load must be kept as low as possible as illustrated.

Do not overload the cross bars. Maximum load that can be placed on the cross bars is 94 kg or 207 lbs.

Do not exceed the recommended gross vehicle weight (GVW).

Do not load cargo, or accessories, outside of the width of the cross bars.

Always secure long loads, those significantly exceeding the length of the roof, at the ends of the vehicle.
Always spread the load as evenly as possible, on the cross bars, with the lowest possible centre of gravity. Cheers Ian

Thanks Hairy Dan,

Yep, its the issue of the length past both ends of the bars that concerns me. I knew that the weight of the canopy is well below the rated weight of the crossbars but its the fact that most of that weight is going to be overhanging the bars that is the potential problem. I was hoping somebody who may have used them to transport a windsurfer sail or similar might have be able to clue me in

If you got the genuine LR part (VPLER0178), it is pretty limiting: The bars are fixed length (a shorter one and a longer one) which fit at the notches in the roof rails, but don't really fit anywhere else (as the roof rails are not parallel).
This means you cannot space them really far apart if you need to.

The Thule option allows the bars to be placed anywhere, as their length is adjustable. No Mud flaps for my 90.!

Don't forget that they also state a maximum speed limited in the installation instructions. Normally 80mph if my memory is correct.

It sounds like the weight is fine, but the question is more about the intrinsic strength/integrity of the awning itself. I guess it depends on the strength of the aluminium casing.

Which Thule awning is it?

It looks like all the guidance is to have the fixing plates right at the ends of the awning

Given the amount of extra weight the bars can take, could you potentially add a long 3-4m, strong (steel) reinforcement plate which fixes onto the bars to add a bit more rigidity further out from the crossbars themselves?

Are you just transporting it, or are you planning to use it on the Defender?

its a Thule Omnistor and I'm just transporting it the once so don't want to go any great lengths/costs to do so. Think I've found somebody with a van I can borrow so that'll be much easier!!! Current: MY22 P400e SE
