3-wheel vs 4 wheel

The rear wheels of the four wheel forklift are not adjoined to the frame of the truck. No suspension, no struts or shock absorbers. Take your 2 hands and fold them together (finger thru finger). Swing your elbows out so your arms are parallel to the gound, and your clenched hands close to your chest. Your elbows represent the rear steer wheels. What are your elbows supporting? N-o-t-h-i-n-g!!!!!! As are the rear steer wheels of a 4 wheel sdcb forklift. However, where your hands are clenched, is known as the pivot box, which controls the steering of the rear steer wheels, and provides approx 3" of suspension to the rear of the truck. And its that pivot box that is the third and last support point on a 4 wheel sdcb fl.

That is how I explain why there are only 3 support points, not 4.

BTW, I have Powerpoint presentations for each and every class of forklift, except zoombooms, and I do explain the stability factors of each, separately.

And, I have never trained on a Bendi, yet seen one.

Thanks for the input.
