Sanderson 622 Safe load indicator

[Jon_B]

Good afternoon,

We've a tired old Sanderson 622 teleporter. She's mechanically sound and we have no real problems addressing a few niggles. The aim is to bring it up to standard to pass a LOLER inspection. The problem at the moment is the electrics and a missing safe load indicator (assuming it was faulty or removed by a previous owner) I read somewhere the original was also slightly over engineered / complicated. I've seen some but at over £2K thats prohibitively expensive on a £5 machine. Alternative solutions would be appreciated , thanks.

Sorry, that should read a £5K machine

I agree setting these sli up was a bit brain knackering, the boom extensionometer would sometimes break the cable and write off the pot inside the drum, i have set or tried to set up lots of these and i know the kit was very expensive only fitted one load cell, mainly box in cab and boom component, but have no idea if you can fit a different type.

Talk to @ACEngineering. The axles are similar to the early 4 wheel steer Manitou. It might be possible to fit a cell to the axle and a Manitou warning box in the cab. The Sanderson effort was cr@p when new.

From past experience on an old Claas ( early Sanderson I think ) the price of a load cell alone is prohibitively expensive so having to refit a whole system could be very expensive.

Fairy sure most of the original Sanderson system is obsolete now.

But theres a way better cheaper option.

Ring loughborough university I think it is
They probably made the original system
I reside a tx525 a few years back and their system was a lot less than just a sensor from dealer

The original system is a load of crap IMO i think most of it is obsolete and was always stupid expensive, needed a special kit to calibrate it and repair it which few people have.

Clean off the top of the diff on rear axle. Hopefully you have a flat spot on the top of it and 2 threaded bolt holes.

I can sell you a load cell with the fixings and the wiring up to the cab, and a read out box to mount in the cab. All you need to do it make a bracket to mount the read out box, provide a earth and a fused 12volt feed to the box, mount the load cell and route the wire up to the cab and plug in the box. Then its just a simple press button calibration with the only special tool required is a small poking device like a match stick or similar. Costs roughly about £400 plus vat your time fitting.

if you do it nicely like my last customer did it will look factory fitted

TX and TL range was a total different system Similar to matbro which you could fit but it isn't as good as the system i use which is also cheaper.

Manitou had one similar on the first MT420FC around early 80's- box on chassis under the cab footplate, extension meter for boom, and one measuring angle of boom - poor reliability - very expensive - too complicated

That’s cool. Mine is currently working but in the future....

If it looks like one was never fitted, is a laminated chart in the cab not good enough?
I think the idea was that as your nose pressed against the front screen, you could refer to said chart for confirmation that you should by now have passed the point of balance..

Thanks all,

It looks like ACE's solution is probably the best solution. We'll have at look at that and hopefully come back with a success story, Cheers

Thanks but not an option, as it was fitted originally there's no scope for not having one. You're right though nose on screen is a clear indication of been passed tipping point

I fitted one of the Manitou style SLIs from @ACEngineering to a Sambron.

The sensor on the Sambron was on the chassis on the axle pivot but the axle already had the correct holes tapped on top so I fitted the new one there.

Panel fitted into the dash.

Works well

Does SLI have to be a mechanical device? On tail lifts it's just a sticker advising max wt?

A tail lift doesn't lift enough to tip the whole vehicle over does it?
Or have an extending boom.

Ah so that's why your booms cracked??
