Tilt Table questions

Tilt Table questions

Tilt Table questions

(OP)
I've got a new type of Forklift under construction and am trying to get information about OSHA tilt table parameters. ie the basic methodology of the tests. I've been told by a manufacturer that its a fairly simple device (our forklift prototype weighs 2300lbs) made from a diamond plate deck with a hydraulic cylinder, and tie downs for the unit being tested. Obviously an inclinometer would have to be used. Also what type of an engineer would be needed to certify the results?

Any help would be greatly appreciated.

RE: Tilt Table questions

OSHA has nothing to do with forklift tip testing. The applicable standard is SAE 56, with different sections for different types of forklifts. 56.1 is counterbalance warehouse. 56.6 is offroad telehandlers. I believe that SAE recently distanced itself from these standards  because they didn't make enough money selling papers. I believe that there is some sort of manufacturers organization now. In fact these tests are "voluntary" but it will not stop you from getting sued. OSHA just wants to see that it meets the SAE standard. I almost forgot, there is also a ISO version that is very very similar.

As for the test parameters, there are tip goals for 5 different scenarios. Forward and lateral tip with and without loads at different heights. And just because a wheel lifts does not mean that you have failed, the truck must loose stability.

Like most standards, some things are spelled out very specifically and some are not. Several are:
-wind limit or wind loading(if outdoors)
-wheel orientation
-can the operator's weigh help meet the goal
-fuel load
-orientation of moveable attachments
It can get quite involved. To cover ourselves I wrote a 10 page test procedure that basically detailed our interpretation.
