This is part 2 of the challenge: the 20 questions. Pick one of the three options, check your answer and keep going. Your score shows up after question 20 and stays on your phone only, so nothing is sent anywhere.
Below the challenge you will find how to read your score, what each of the seven topics covers, answers to common questions, and three apps to practice the controls on your phone.
How to read your score
There is no cutoff score. At the end you see a line like “In our challenge you got 14 out of 20”, with one to three marks for the result. Under “Topics to review” you see the topics where you missed a question. “Try another set of questions” loads a different set of 20, and there are three sets in total.
A low score says nothing about you as an operator. It only shows which topics deserve another read. Go through the topics below, then try a new set. What really counts in the cab is practice with someone experienced beside you.
The seven topics
Controls
Which joystick moves what. In both ISO and SAE, swing is on the left joystick and the bucket on the right, moved side to side; the boom and the stick trade hands between the two patterns. It also covers the travel levers of a tracked machine, where each lever drives one track, and the backhoe, where the stabilizers go down before the rear arm digs.
Inspection
The walk-around before the machine goes to work each day: fluid levels, leaks, tires or tracks, lights and the backup alarm. On a forklift, fluids and forks are checked with the engine off, and brakes, steering and horn with the engine on. A machine with a leak or a defect stays out of service until it is fixed.
Hand signals
The standard signals between the signal person and the crane operator: hoist, lower, raise and lower the boom, swing, travel, stop and emergency stop. Directions are always given from the operator’s point of view, and anyone who sees a safety problem may give the stop signal.
Forklift
A forklift steers with its rear wheels, so the tail swings out on turns. The load travels low and tilted back, faces uphill on a steep ramp, and a tall load is carried in reverse. The capacity plate shows the most weight the truck can lift at a stated load center.
Crane
The load chart is a grid of boom length and radius. Capacity drops as the radius grows, the highest numbers assume outriggers fully extended on firm ground, and the hook block and slings count as part of the load. Going past the chart can tip the crane or break the boom.
Safety
Seat belt on, people outside the swing radius, nobody under a raised load, and a working backup alarm or a spotter when the rear view is blocked. At the end of the shift, the machine stays on level ground with the bucket down and the engine off.
Work site
Underground pipes and cables are located before the first scoop, the spoil pile stays back from the edge of the trench, and an overhead power line of unknown voltage is treated as live. The ground under a crane must hold it firm and level.

Practice the lever pattern on your phone
The three apps below are games from the store. They are a good way to get used to the lever pattern and the feel of the machines, but they do not replace time in a real machine with someone experienced beside you.
