Pass through - ideas

Postby Rusape » Tue Feb 25, 2020 11:26 pm

When designing the build, I decided I didn't want a single door between the cab and the box, with a padded insulating infill in between. I wanted a weathertight, secure, noise suppressed pass through.

I figured the best way to achieve this was to have 2 doors, one in the cab and one in the box. Both lockable and both providing a proper noise-insulated seal. See pic below

Now the distance between the two doors is aprox 450mm, small enough to traverse, but big enough to make it uncomfortable. I wanted to avoid a concertina gaiter-seal, and will have an overlapping gutter arrangement overhead to keep rain off.

I have a plan to aid easy crossing when needed, but does anyone one have any clever ideas of how to bridge the gap between the doors to allow easy ingress/egress.
I don't want a permanent connection as it's a cab over, so something simple and effective.

I'd welcome any advice/ideas.

Lazz,
I'll be keen to hear what others suggest as I was thinking of the same sort of arrangement, although it is all still planning at this stage. Best I could come up with was to hinge one door at the bottom to use as a 'plank' across the gap, however this needs thought on relative door sizes/heights /widths as the bridge door would ideally rest on the other cill. I think you will also need to be able to unlock both doors from inside and outside for full flexibility.
See what ideas the others have, Pete

I think a gap that size will be problematic, unless you could develop Pete's idea into a hinged step of some sort.
I also have two doors, but 180mm between cab and box and acordian rubber, with clipped frames for cab tilting.

I'd personally just make a hinged / sliding platform to step on whilst traversing and leave the rest totally open.

L - PMd you also.

How do your doors operate Ivan? (open/close)

My box door opens inwards and the cab hinges inward and upward.

Pete, that was the problem, to have a door large enough, it was impossible to have a drawbridge style, as the gap is too small and the door needed to be quite large to get my bulk through.

Understand the door needs to be large enough to get through - say 700mm high by 500mm wide? But can you make the second door wider (say 520mm) and opening inwards so the first door can drop inside the frame of the second door?
Can see it will still be messy reaching door handles and so on. Needs some creative thought... Looking at the picture more closely it may be too late as it seems your cab door opens outwards and is hinged to the side. Stick with to Steve's hinged step?

Yep I thought long about a solution when designing.

My cab door opens inwards, as does the box door. Makes ingress/egress much easier albeit I have had to have the cab hatch door open the wrong way, as it were. ( the ram is on the outside and the inner handle is outside) I spoke to and met Outbound, who supplied both doors before ordering and this was the only solution that worked that they were happy with and would warranty.

The same - cab top hinged opening inwards and the box side hinged, opening inwards.
It was the only way I could see to retain access and preserve the insulation of both the cab and box.

I think a crawl through is one of the hardest things to design and build, also a very individual part of the build, some swear by them and some swear at them.

Me personally, I love it!

I have tried various ways, but in the end I have gone for the simplest way possible.

I will not bore anyone with describing my design in detail, as to be honest there is no detail! It is simple, and above all, it works perfectly. I will however give a link to a picture or two. The last picture is the most up to date image, showing the cabin side, but not showing the foam plug.

All I have is a tunnel attached to the cabin outside wall, and another tunnel attached to the cab back wall, simple, and to close the tunnel I just fit a couple of foam plugs, one in each tunnel. These keep out the noise and fumes from the engine and as I have fitted a cover between the cab and cabin, there is no water ingress.

The only issue I would have is when I tip the cab and it is raining, but I have a few ways of sorting that if indeed I need to.

As for security, I am not totally convinced I need any, but one way I am thinking about is just a few wood "slats" that drop down into channels that can be locked into place if needed, but that will only be used for parking as it is nice to have another "escape" route from the cabin to the cab, plus the blooming dog knows how to barge his way through!!!

As an aside, my WordPress website has updated something, and now my photo albums do not work and I am not at all happy with it, so please bear with me till I can find someone that can fix it for me, as I do not yet have a clue how to do it!
Why do they always have to update something which always buggers things up!
Sorry about that.
