RE: Fork-lift Trucks

[Subject Prev][Subject Next][Thread Prev][Thread Next]
If your client doesn't know how much weight he needs to lift, you're really
dead in the water.  
If he knows the required payload, you need to look at equipment brochures,
or maybe a cost estimating guide such as Richardson will give info on the
truck weight.  I'm not aware of an easy rule of thumb to get that.
Conservatively, the front axle (next to the forks) will take not more than
100% of the combined weight of payload and vehicle before it overturns.
IKG, before they merged with Borden, had charts in their grating catalog (ca
1973) for different sizes of forklifts.  They were based on 85% of combined
load on the axle, and recommended a 30% impact factor.

Hope this helps some.

	Hello,

	Is there anyway to get generic information for forklift trucks.  Say
if 
	the owner needs a 3000lbs capacity truck it will typically have a
wheel 
	spacing of 37" and for pneumatic tires a contact area of 10 in^2 and
an 
	axle load of 12500 lbs.  This would be handy for designing slabs on
grade 
	in warehouses where the owner does not know who he will get the
trucks 
	from, just that he needs some (and usually does not know the
capacity 
	needed).


	Thanks, 

	Mike
