    Default Bakkie hard tonneau cover design idea

    Hi guys

    Firstly I hope this is the right section...

    Secondly, I need some input on an idea for a hard tonneau cover for my Isuzu.

    So far I have done a CAD design based on the measurements of my bakkie and standard steel sizes that are available. The main frame consists of a 50x50x5mm angle iron frame that rests inside the load bin. Inside this frame is a 25x25x3mm angle iron frame recessed just enough to have a sheet of chequer plate flush with the main frame. Then I will also include a roll over bar for safety reasons at the rear sliding window. The plan is then for this whole contraption to bolt to the bakkie using the same 4 bolt holes where the canopy bolt onto.

    There is no door section to this cover as I keep all my stuff in crates and don't mind something slipping to the back of the load bin. If I then really need to load something taller I would have to put it on top of the cover or unbolt the cover and put it upright in the load bin.

    I weld like doves poop, but can grind like a champ so will probably have to tack the frame together using a few corner clamps and magnets and then ask a friend to help out

    The attached picture shows (from left to right) a sort of isometric view, view from rear of the bakkie and the side view.

    Any ideas or advice would be appreciated.

    Or you could just buy one of these, had one on my previous Navara, check out the video on how they work.

    I like the idea.

    Was thinking about a square tube cattle rail thing for the Tata, also using 50mm angle as a base bolted onto the top of the loadbin sides, then 50mm square tube rails.

    Some ideas for you:

    " Inside this frame is a 25x25x3mm angle iron frame recessed just enough to have a sheet of chequer plate flush with the main frame."

    Maybe consider hinges at the front end and then trailer door catches (two x Antiluce with padlocks)




    at the back end and you can lift the lid at the back when needed.

    Thanks, would have been nice if I could afford something like that.

    I actually had this whole idea of a removable section that would fit between the wheel arches on the load bin floor, but ultimately decided against it in favour of a simpler and lighter setup. If my calculations are correct, this setup comes in at just below 40kg.

    Also, I will be using cup square bolts (attached) to fasten the cover to the bakkie. Space between the cover and canopy mount is not that much.

    I've often thought of this only difference in "my design" if you can call it that is to make the solid cover in 3 sections. The section closest to the tailgate having a hinge with the two rears locked together internally, this way if the need arises for something taller the cover in that section can be removed...

    Well.... OK. The tribe has spoken.


    It would be possible to split the cover and then secure the loose part to the roll bar r put it on the load bin floor with the tail gate open. Will see if I can make a picture with the cover secured to the roll bar, but have to look busy for a while

    The cover will still only use the four canopy mounting points and the two sections will be bolted together in the middle.

    Make the sections interlocking in some way, even a simple slip fit then you only require locking the first section to secure it.

    Should be a cool project

    With the cover put on the roll bar it only protrudes about 80mm above the roof line of the canopy.

    The other day I saw a single cab Hilux with a similar setup to my "design" and I must say, that angular square tubing roll bar looks... well... crap.

    So best option would probably be a pipe or bent tube setup similar to standard, but that is outside the scope of my abilities.

    Anyone with a better looking solution to the square tubing roll bar?

    Get 50mm mandrel bends from your local exhaust shop and build a nice rollbar.
