Re: High Tire Pressure on Concrete slab

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Gail,
 
I'm not sure why those numbers were inserted into this inquiry.  Perhaps he was using an example.  The pressures I have as stated in a previous email are;
 
"I don't believe the tires are inflated.  I agree, 900 psi tire pressure is high, that's my problem.  I am using a Jungheinrich ETXac 125 fork truck.  The brochure states the tires are "Tractotan".  The published contact pressure is 620 N/cm^2.  My conversion program puts that at 899 psi."
 
I never heard of "Tractotan".  An Internet search came up with only 2 web sites, not in English.
Thanks.
 
Rich

Average contact pressure:

Please include the dynamic multiplication factor

a. Braking                  1.3
b.cornering                1.4
c. Acceleration           1.1
d. uneven surface       1.2       
Where are all these numbers coming from?
