Operator training must be class specific. A class 7 (rough terrain) lift truck can be very different and used in very different environments than a standard warehouse forklift. They can have extendable booms requiring boom angle and extension to factor into rated capacities. They can have frame level, locking rear oscillating axles, multiple attachments, traversing boom mounts, high or low boom mounts, multiple steering modes, axle traction controls, special load and unload procedures and multi-speed transmissions. They require special site specific training concerns and special operational techniques. I have included both in the same classroom. There are some common rules that apply to both. With the classroom and two separate hands-on evaluations with a standard group of 8-10 it took me 6 hours.
