Forklift Feet Spacing Standards
Forklift Feet Spacing Standards
(OP)
I am currently working on a design and I require forlift pockets in my design. I believe that the standards for spacing the pockets are based off of load capacity for the forklift. I think the standard can be found in ISO 1496-1 Annex C, but I do not have acess to that standard and do not want to pay $50 just for one spec.
Does anyone kown where I can find this spec with out paying for it? Do I even have the correct one?
My desing will have a max weight of 50,000 lbs.
Thanks

Check with a couple of the major manufacturers for the dimensions of their machines (Hyster and Caterpillar, for instance).
Fork spacing will be dictated by the type of load to be picked up as well as the weight of the load. If it is a wide load, then maximum fork spacing would be dictated. You also have to consider the self weight of whatever is being picked up...can it withstand the maximum fork spacing?
RE: Forklift Feet Spacing Standards
Ended up getting the customer to tell us all the sizes of pallet truck that they would be using with our container and designing around that.
That said, maybe for something like that weight you may be able to do better, perhaps matching ISO or similar standard containers.

Regafding fork size, there are a large variety of sizes and types used by various manufactures. We have, for example a Taylor (45,000 lb capacity) with forks that are 10"x5"x96" and a Royal (43,000 lb capacity) with forks that are 10"x4.5"x96".
If you don't know what forklifts you device might be handled by, make sure your fork pockets are large enough to accomodate a presumed worst case.

Also be aware that forks of the same capacity can have different cross sections. Instead of looking at the forklift OEM's, who will sell whatever forks you want, look at a fork manufacturer.

One point that needs to be made is you can save yourself a lot of work if you can use an existing design fork or have your design built by someone who deals in same. Another is pay careful attention to the yoke if you use chain lifts as this has been the location of most defects found during semiannual inspections.
Like the others I've haven't run across any standard for general use forklifts. If in the US you will need to get the OSHA standards for all the tests required for a new design or modification. We got burned bad for an unauthorized modification to a high lift fork truck.

RE: Forklift Feet Spacing Standards
In the case of telehandlers several weights must be tested at several different extensions to create the load chart. Operator weight is either 0lbs or 200lbs, whichever is the worst scenario. The fuel tank level is also dictated by the worst case scenario. And tire make/model, size and inflation pressure have a huge influence.
In the case of counterbalance trucks there can be hundreds of different mast, carriage, fork, engine, fuel type, tire and counterweight combinations.
I can tell you from experience that it is very difficult to calculate the actual tipping points. Telehandlers have few options so they are usually tested. For industrial trucks the OEMs have built their own database with past experience that has helped them develop fudge factors for the different options. Then they only have to test the major changes from one model to the next, put that in their model, and they can calculate the hundreds of permutations.
The big concern that OSHA has is nobody but the OEM is going to know or understand what all goes into these stability calculations. And when Joe Bob modifies his forklift and kills himself, the widow and her three little kids go after the big bad forklift company. We had one case were the guy admitted to drinking a pint of vodka and a 6 pack of beer for lunch...and he still won!?!
As unclesyd was saying, OSHA doesn't mess around with this. And you can see why the forklift companies will not approve your homebrew design, unless you want to pay some money to have the design reviewed and possibly tested.
