forklift mast lift height T071
 

If a Yale forklift has a T071 mast how high does it go? T071 stands
for Triple, 71" lowered height. I found that so far, but cannot find
a chart or listing that gives max height.

15ft my best guess

I was thinking less. 71" lowered seems small. The one I have now
is 84" and a triple and it will do 13 feet. But then it is a late
60's early 70's model.

Yes, 71" lowered does seem small. The lowest height mentioned in a
chart on page 4 of a not-necessarily-applicable Yale pdf* is 89".

For the 3-stage lift options listed in the chart, the highest-raised
platform height is consistently 87" less than the highest overall
height, and the ratio of highest overall height to lowered overall
height ranges from 3.11 to 3.17, per following python program. If
you find out the appropriate ratio for your model of lift you could
get estimates for highest platform height and highest overall height.

Python program:

l=(89,95,101,105); h=(282,300,315,327); t=(195,213,228,240)
print ' i l t h h-t t-l (t-l)/3 t/l h/l'
for i in range(4): print '{:2} {:3} {:3} {:3} {:4} {:4} {:6.2f} {:6.2f} {:6.2f}'.format(i, l[i], t[i], h[i], h[i]-t[i], t[i]-l[i], (t[i]-l[i])/3., float(t[i])/l[i], float(h[i])/l[i])

Output from program:

i l t h h-t t-l (t-l)/3 t/l h/l
0 89 195 282 87 106 35.33 2.19 3.17
1 95 213 300 87 118 39.33 2.24 3.16
2 101 228 315 87 127 42.33 2.26 3.12
3 105 240 327 87 135 45.00 2.29 3.11
